7,62 x39 Cartridge has a symbol: 7,62 x39 / 7,62-mm cartridge arr. 1943 / 7,62 x39 Kalashnikov / 7,62 x39 AK-47 / .30 Russian / 7.62x39 M 1943 / 7.62 mm M 43 / 7.62 mm Klashnikov / 7.62 Russian Short / 7.62 Vz.57 / SAA 2560 / XCR 08 039 BGC 010

Work on the interim holder of the Soviet Union began in 1939, although the question was put about that much earlier. To study the question was designed cartridge caliber 5,45 mm, and was given the task of automatic rifles for the design of this cartridge. However, with the beginning of the Great Patriotic War, the designers have been diverted to more urgent work.

Development of intermediate cartridge was re-launched in 1943, after members of Technical Board of the People's Commissariat of arms (IEC) were introduced to the captured samples captured at the front of the Nazis, as well as provided to the USSR to familiarize the American self-M1 carbine.

Particular attention is attracted professionals new German bullet caliber 7.92 mm with a length of 33 mm shells and developed under his carbine DCA 42 [N] to be tested in the current Army. This cartridge has a length of 48 mm mass of 16.2 g. When the mass of the bullet 8,2 g and the initial velocity of 700 m / s it provided sight-range shooting at 800 m. At the meeting it was decided that the need for a patron for the replacement of the reduced power rifle cartridge in such weapons as the self (auto) rifle and hand gun, as well as new types of small arms under him. This cartridge has a length of 48 mm mass of 16.2 g. When the mass of the bullet 8,2 g and the initial velocity of 700 m / s it provided sight-range shooting at 800 m. At the meeting it was decided that the need for a patron for the replacement of the reduced power rifle cartridge in such weapons as the self (auto) rifle and hand gun, as well as new types of small arms under him. On the basis of a new intermediate cartridge was easy to create customized automatic weapons are more effective range of fire than the pistol-machine gun. On the basis of a new intermediate cartridge was easy to create customized automatic weapons are more effective range of fire than the pistol-machine gun. Responsible for the development of a new cartridge was designated OKB-44 (later SRI-44, which in 1949 became part of the NII-61 and upgraded in 1966 in TSNIITOCHMASH).

To determine the optimal characteristics of the holder were calculated on the choice of the velocity and bullet weight for the caliber of 5,6 mm, 6,5 mm and 7,62 mm. Those calibers were selected as the most frequently encountered in practice.

The new holder caliber 7,62 mm were the following requirements: bush needs to be a modern form - without flange, lower weight and dimensions than the rifle cartridge, reduced to 20% (compared with a rifle) power chuck; energy bullets at the range 1000 m should be not less than 25 kgm. Interim cartridge was used to fire from automatic carbines, machine guns, automatic rifles and machine gun hand. Weapons under a new cartridge should be easy, including by reducing the length of the trunk. To this end, thought it possible to use rifles, machine guns (rifles) fine rifle barrels, without fear of overheating, because the shooting of which was to be carried out mainly by single shots, and only sometimes in the most critical moments of battle - automatic fire. Considering flat trajectory of one of the main characteristics of the holder of the OKB-44 from the beginning, it was agreed that this cartridge must be better than German. A patron 7,92 x33 range of direct shot (DPA) was 300 m, for our adopted DPA equal 325 m. It is September 3, 1943 by the Technical Council of the IEC were considered the first two option holder has been chosen one of them (later called the 7 ,62-mm sample 1943). Following the September meeting of all the weapons CB Research and testing of small arms and mortar GAU (NIPSMVO) have been initiated to develop a forward-looking automatic weapons ammunition.

In December 1943 the first batch of cartridges with a bullet with lead core (this assigned code holder 57-H-231) was tested on the ground. After some refinement, with the March 1944 issue has begun pilot production of 7.62-mm cartridges arr. After some refinement, with the March 1944 issue has begun pilot production of 7.62-mm cartridges arr. 1943 The original version of the holder sleeve has a length of 41 mm and a bullet with lead core, without the rear cone, and a short head.

Developed in that time, samples of weapons under a new cartridge - automatic rifle and automatic rifle (machine) - were designed primarily for shooting single shots. It was assumed that an automatic fire while shooting an automatic rifle was used only in close combat (in the range 100-200 m). Accordingly, during the development of a Bullet arr. 1943, focused on providing the necessary accuracy of shooting single shots, the shot-range of direct and punchy action bullets. High accuracy of fire with automatic fire from the new holder is not required. But later, after the adoption of the AC, the main type of fire from machine to improve the density of the fire (fire density - the number of pellets per linear meter per minute), have come to believe the shooting in bursts, regardless of the distance to the goal. It is fair, it should be noted that the probability of falling into the goal when shooting in bursts increased but slightly, while consumption increased in proportion to patrons queue.

In 1944, after receiving the first results of tests, started work on improving the holder in order to improve its accuracy and penetration. Headache (ogival) of the bullets had been extended, which made it possible to improve the ballistic coefficient, while maintaining the mass of the bullet. A bullet had entered the rear cone, thus reducing air resistance bullets fly, not only as if it was thought at subsonic speeds (ie, when shooting at long range), but also with supersonic speed bullet. To keep the overall length of cartridge casings dultse was shortened by 2 mm, and increased depth of planting a bullet in the sleeve. To keep the overall length of cartridge casings dultse was shortened by 2 mm, and increased depth of planting a bullet in the sleeve. Bush won the final length of 38.7 mm (in the marking of the length of 7,62 x39 cartridge casings indicated rounded). After that, work began on replacing the lead core of steel. The bullet with steel core has received the name - «surrogatirovannaya». Its length has increased from 22.8 mm, the first option, to 26.8 mm. The main argument for the use of low-carbon steel core, it was not so much an increase in disruptive actions of a bullet, but the savings deficit lead (50%) and manufacturability stamping core. Besides the technology of manufacturing has been borrowed from the holder of TT. It should be noted that while the primary measure of disruptive actions of a bullet was to evaluate the possibility of Perforation of steel Army helmets at ranges of 800 - 1000 m. By mid 1947, all marked on the test gaps holder arr. 1943, with an ordinary bullet was removed, and the GAU has decided to manufacture a series of rounds of ammunition and advanced weapons for the military trials.

In order to enhance the tactical capabilities of weapons of perspective, and based on the experience of creating 7.62-mm rifle cartridges for various purposes, along with the patron with an ordinary bullet, was the development of ammunition arr. 1943, with special bullets: armor-incendiary (designed in 1944), incendiary and tracer (developed in 1948). 1943, with special bullets: armor-incendiary (designed in 1944), incendiary and tracer (developed in 1948). In 1949, in conjunction with a Kalashnikov assault rifle by the Soviet army had been taken, and 7.62-mm cartridges arr. In 1949, in conjunction with a Kalashnikov assault rifle by the Soviet army had been taken, and 7.62-mm cartridges arr. 1943, with the listed types of bullets. Subsequently, improved patron arr. 1943, with an ordinary bullet with steel core was carried out to improve the disruptive actions of a bullet (for the destruction of living force in the personal armor), a tracer, to increase the burning time tracers and delay the start of combustion. In improving the bullets great importance was the use of a new charge gunpowders spherical granulation. It is known that the priority of creating a spherical powder granulation belongs to the United States. Its main advantage - graviometricheskaya high density (density of filled shells) - about 0.85 g/cm3, the increased progressiveness of combustion and high-tech manufacturing. This allows, with equal charging chamber, to ensure greater muzzle energy of the pool, or, with equal muzzle energy, reduce the size cartridges.

Initially the 7,62 x39 cartridge manufactured only with bimetallic shell - steel clad tombac. But in 1948, owing to difficulties in obtaining the bimetal, the bulk of which is mainly supplied from the United States for lend-lease, machine sleeve chuck latunirovannoy were made of steel. Process latunirovaniya brought in German industry, was associated with the use of potent poisons. Therefore, with the development of production of bimetal with the Soviet Union in 1952, automatic liner again made from this material. Subsequently, in early 1960, the number of enterprises has been the production of steel and lacquered shells (coated with varnish green), which provided significant savings tombac. Even in our time, production of steel shells with a polymeric coating (water-polymer solution), which significantly reduced the harmful production.

Battle cartridges:

Cartridges with ordinary bullets fired «7,62-mm cartridge arr. 1943, with a bullet with steel core FP »(FS - bullet« surrogatirovannaya »; subsequently began to use the term -« bullet with steel core »), the so -« 7,62 R », is intended to destroy living purposes, located in public or Light for shelters, soft-skinned vehicles and fire equipment. Initially, the cartridge with a bimetallic shell code - 57-H-231S. Began in the early 1960's cartridge with steel lacquered shell received code - 57-N-231SL. But over time, felt it inappropriate to specify the material cartridges index cartridge, and cartridges with a bullet with steel core have been a single index - 57-H-231. Common bullet consists of a steel shell, clad on both sides of a layer of red brass, stamped steel core of low-carbon steel 10 and lead-shirts. In the middle of the bullets performed knurl ring, which upset dultse sleeves when assembling the holder. In the 1960's, was constructed and tested a pilot batch of cartridges with bullets FS, steel shell which instead tombac was covered in green paint. Netermouprochnennym core bullet with a steel punch helmet at a distance of 900 m and fragmentation vest at a distance of 600 m. The distinctive color of the bullet of this cartridge does not have.

Since 1962, dultse the junction of shells and bullets fired from the edge primers to improve the moisture-borne varnish germetizatorom. In the 1962-1963 biennium. nail polish color was purple, and from 1964 lacquer on cartridges with any type of bullets has become red. Since 1984, when instead of rifle piroksilinovogo gunpowder was used spherical powder granulation, at the rear of the bullet was made to facilitate the assignment patronirovaniya. Give address getting smaller poroshinok dultsa between the walls and bullet. The distinctive color of the bullet cartridges also no.

A long time, the question of technological production cartridges prevailed on a possible increase in disruptive actions of a bullet - as you know, it is provided in the basic materials and form the core. In particular, to prevent hardening the core, but its form was determined by labor-stamping. In particular, to prevent hardening the core, but its form was determined by labor-stamping. Nevertheless, the wide dissemination of personal armor, providing protection from the bullets with a steel core of low-carbon steel, required to improve patrons. Beginning in 1989, to increase the disruptive actions of the bullets began to apply the core termouprochnenny increased hardness. Its made from vysokouglerodistoy spring-spring steel grades 65Г, 70, 75, followed by heat treatment. Disruptive effect of the bullets with a new core for a strong barrier to increased 1,5-2 times. The bullet to the core provides termouprochnennym of Perforation of steel helmets at ranges of 1000 m; fragmentation vest at a distance of 700 m and protivopulnogo armor that protects against bullets from automatic netermouprochnennym core, at a distance of 100 m. The distinctive color of the bullet of this cartridge does not have. From bullets to netermouprochnennym core a new cartridge can be distinguished only by year of release.

Cartridges with a tracer bullet:

«7,62-mm cartridge arr. 1943, with tracer bullet T-45 », the so -« 7,62 T-45 », the index - 57-T-231P is designed to target and adjust the lamp at the firing range to 800 meters, as well as to engage manpower . Cartridge comes with bimetallic or lacquered steel cartridges. In the period from 1949 to 1951. including cartridge manufactured with latunirovannoy shell.

In bimetallic shell tracer bullets in her head, zapressovan core of the lead-surmyanistogo alloy. Behind the house the core tombac clad steel cup with zapressovannym a pyrotechnic composition (vosplamenitelny, transitional, and trace). To avoid damaging the tracer bullet of the T-45 has no knurl. In the bottom part of the bullet is enshrined ring, it performs the role of the nozzle and provides a uniform expiration of the products of combustion of the tracer.

When firing from the combustion of gunpowder charge is transferred vosplamenitelnomu composition. After the departure of the bullet from the barrel bore from the burning of vosplamenitelnogo and then transferred to the Transitional tracer composition. Burning, glowing bright tracers gives trace of red, clearly visible day and night. If ingestion of bullet is capable of easily ignite them. In 1973, tracing the cartridge has been redesigned. Changing the design of bullets has increased the volume of the charging chamber, thereby facilitating the selection of the charge on different batches of gunpowder, to ensure the stability of ballistic performance and failure to obtain employment of weapons.

This modernization of tracer holder conducting staff TSNIITOCHMASH - VM Sabelnikov (manager), PS Sabelnikov (manager), PS Korolev and AT Korolev and AT Khomyakova. In the late 1990's, engineers TSNIITOCHMASH LI Novozhilov, etc. Novozhilov, etc. Vasilyeva was upgraded bullet tracers T-45. The new cartridge was the full name - «7,62-mm cartridge arr. 1943, with modernized tracer bullet T-45m ». It was adopted in 2002 under the symbol 57-T-231PM1. Upgrade would increase the range of trace to 850 m and has started burning tracer composition in the 50 - 120 m from the muzzle cut. This delay allows for better combustion tracers mask fire an arrow, and provides continuous monitoring of the battlefield through the night sights from the electron-optical converters. Vershinka tracer bullets bullets all painted green. There are cartridges with a tracer bullet, made in early 1960-ies. Having no color, but with germetizatrom green at dultsa sleeves and on the edge of cap.

Cartridge with armor-incendiary bullet:

«7,62-mm cartridge arr. 1943, with armor-incendiary bullet BR », the so -« 7,62 BR », index - 57-BR-231, is designed to defeat the purposes of light, igniting the fuel behind armor or thick-walled container, and for the destruction of living force behind the guise of light armor at ranges of up to 300 m.

Cartridge manufactured with latunirovannoy or bimetallic shell. Armor-incendiary bullet consists of a steel, coated with a shell tombac tompakovym point, heat-treated steel core with a lead jacket and the incendiary composition is in the lead pallet. When the bullet hits on the breastplate of lead pallet, moving on inertia forward, compresses the incendiary composition and thus ignite it. Flame through the hole, пробитое steel core, penetrates the zabronevoe space and is able to ignite the fuel.

Armor-incendiary bullet pierces the steel helmet at a distance of 1100 m and a fragmentation vest at a distance of 1000 m. Plate armor thickness 7 mm punches at a distance of 200 m. Vershinka bullet is painted black with red bands. In cardboard boxes, metal boxes and wooden crates of bullets sprayed BR oblique black and red stripe.

Cartridge incendiary bullet:

«7,62-mm cartridge arr. 1943, an incendiary bullet G », the so -« 7,62 W », index - 57-3-231, for ignition of flammable liquids (gasoline, kerosene) in steel tanks with wall thickness up to 3 mm, as well as easily illuminated material (dry grass, straw, etc.) at distances up to 700 m. According to their construction and operation of the bullet «7,62 W», is a type of incendiary bullets to fire pyrotechnic composition, and a piercing, tracer, providing surveillance of the shooting on good visibility (up to 700 m day and night) along the red. Cartridge manufactured with latunirovannoy or bimetallic shell. The bullet consists of a steel, coated tombac, envelope with tompakovym point, incendiary composition is in the head of the bullet, the core of low-carbon steel jacket of the lead-antimony alloy, bimetallic cup with pyrotechnic composition (vosplamenitelny, transitional, and trace) and the ring (the designation is the same as in other tracer cartridges).

When a bullet hits a hard target occurs sharp dynamic compression and heating of the incendiary, moving forward steel core, resulting in the incendiary composition ignite. Wrinkle point bullets, the shell is deployed, and the flames of incendiary composition provides lighting purpose. At a meeting with the target low-density, due to the low sensitivity of bullets, incendiary composition may not ignite. There are two versions with different bullets ogival radius parts. More acute, appearing at a later date, to a lesser extent, deviate from the trajectory of bullets FS. Vershinka bullet cartridge «7,62 W» is painted in red. In cardboard boxes, metal boxes and wooden crates with incendiary bullets sprayed oblique red band. Cartridge with armor-flammable and incendiary bullets were collected manually and have a high cost. Planned to use them only during the period of hostilities. For training, these cartridges are usually not used. Once had accumulated sufficient reserves of ammunition with a bullet BR and W, their production was discontinued. Currently rounds with armor-flammable and incendiary bullets removed from production, but may occur in the army reserves.

Cartridge with a bullet to the reduced speed:

In mid-1950's to equip the intelligence and reconnaissance and sabotage units and the hidden destruction of unprotected living purposes in a range up to 400 m has been developed and adopted in 1962 by the «7,62-mm cartridge with a reduced rate of U.S. bullets», the so - «7,62 U.S.», index - 57-H-231U. This cartridge is designed for firing from AK (AKS, AKM, AKMS, AK-103 and AK-104) with devices for silent shooting and besplamennoy PBS or PBS-1. Cartridge with a bullet, along with U.S. appliances PBS and PBS-1 was designed in SRI-61 engineers NM Elizarov (chief designer of the office, set designer), BV Semin (chuck), KV Smekaevym (chuck), LI Golubeva (silencer), ME Fedorov, and MA Kuzmina. Cartridge comes with bimetallic or lacquered steel cartridges. Increased weight bullets (it was 12.5 g) for the purpose of energy conservation has been achieved by increasing its length -33.62 mm (length of a bullet cartridge 7.62 FS -26.8 mm). Providing the necessary steps have been pushing the use of a core of tool steel U12A, located at the head of the bullet. Lead core, which is located behind him, not only provides the necessary weight, but also performs the role of the jacket. The selected diameter of -7.94 mm bullets (all other bullet diameter is 7.92 mm) - ensures tight incision bullets in narezy and a propellant gas pressure in the channel barrel. The bullet, receiving the initial subsonic speed, does not create waves on the ballistic trajectory, and muffler (PBS) reduces the rate of flow of gases from the muzzle of the barrel. The bullet is able to penetrate the U.S. steel helmet at ranges up to 400 m and a fragmentation vest at a distance of 75 m. The color code - black vershinka with green bands. In cardboard boxes, metal boxes and wooden crates of bullets sprayed CS oblique black-and-green stripe.

Cartridge with armor bullet:

The establishment in 1980-1990's relatively light protivopulnyh jackets with a high level of security and the saturation of the ground forces of many armies the world has led to the need to improve the cartridge with an ordinary bullet. In the late 1990's this modernization was carried out at the Barnaul Machine-Tool Plant DI Verona and VV Zaharyaschevym. In the course of modernizing changes were a form, the material (instead of low-carbon steel, have begun using the tool steel U12A) and the heat core. As a result, the bullet was the armor. The new cartridge was adopted in 2002 and received a name - «7,62-mm cartridge sample 1943 with an armor bullet BP», the so - «7,62 BP», index - 7N23. The new cartridge is designed to defeat the purposes of living in personal armor (located in public or behind shelters), soft-skinned vehicles and fire equipment. The device is similar to a bullet cartridge 7N23 (excluding core) cartridge with a bullet with steel core 7,62 FS. Collet chuck - lacquered steel. New patron for more than three times exceeded the penetration of hard targets, with a bullet cartridge FS. At the distance of 200 m core piercing bullets penetrate new cartridge 5-mm armor-plate mark 2P and 250-m protivopul-ing flak jacket type 6B5. In doing so, provided the trajectory of bullets sopryagaemost new cartridge with a bullet with a steel core. Color code - black vershinka.

Cartridge with a bullet with a reduced ability rikoshetiruyuschey:

In 2002 - 2003. for the Ministry of Internal Affairs of the Russian Federation has developed a number of rounds (9x18, 9x19, 5,45 x39, 7,62 x39 and 7,62 x54R) filled with bullets from a reduced ability rikoshetiruyuschey (PRS). Unlike ordinary bullets type FS (pst, FSC), the type of PRS pulyah no steel core. The need to create special cartridges of this type is related to the peculiarities of the tactics of special MUP units, the majority of combat operations or special operations are conducted in the settlements. In doing so, small arms fire is in the small range. In such situations, high-velocity bullets ordinary iron core leads to a lot of rebound from the walls of buildings, concrete fences, pavement, etc. This poses a real threat to the defeat of his troops. Bullets in the same type of ORS enters solid barrier wrinkle quickly lose speed and do not provide such quantities of dangerous rebound as bullets with a steel core.

Blank cartridge:

To simulate the sound of a shot during the shooting training, as well as works by salutes used blank cartridge. Together with the bush fire to idle screw on the muzzle of the barrel automatic or manual and machine-gun fire to create the necessary pressure of powder gases in the barrel, blank cartridge provides the moving parts of automatic weapons. Blank cartridge and muzzle device (hub for firing blank) were developed by NII-61 Designer Е.Т. Rozanova in 1949 received a chuck full name - «7,62-mm blank cartridge arr. 1943 », the so -« 7,62 wifeless arr. 43 »and the index - 57-X-231. Blank cartridges are produced with the bimetallic or lacquered steel cartridges. Blank cartridges, built in 1949 -1951 he was. Have latunirovannuyu steel sleeve. Blank cartridge is different from fighting a lack of bullets and cartridge cases dultsem long. Dultse compression sleeves asterisk and sealing lacquer layer is covered with purple or red. Powder charge consists of 0.73 g of the porous powder pistol brand P-125. Blank cartridge arr. 1943, shorter than the battle, its length is 48.2 mm. When firing from the primers, igniters ignite the powder charge and pressure created by an asterisk unclasp cogging dultsa. The shot is accompanied by a characteristic sound, flash of flame and smoke.

Training Cartridge:

To learn how to loader arms, production shots and equipment stores used a training cartridge. His full name - «7,62-mm dummy cartridge arr. 1943 », conditional -« 7,62 OUCH obr.43 »and index - 57-N-231uch. Chuck is made using the basic details of the holder of an ordinary bullet with steel core 7.62 FS, but does not contain a powder charge and has a cap-oholoschenny igniter or brass cap from the primer-igniter. Cartridge comes with bimetallic or steel lacquered shell. Increasing the strength of attachment to dultse bullet casings, in order to avoid its loss during training on loading arms, provide further crimping dultsa to the pool. Bullet Training patron does not have a distinctive color, but the cartridge holder are made of four symmetrically located longitudinal vydavki.

Cartridge high pressure:

Cartridge high-pressure, full name - «7,62-mm cartridge arr. 1943 high pressure », conditional -« 7,62 WA arr. 43 »and the index - 57-H-231 B, has been developed in SRI-61 (leading designer KV Smekaev). WA Cartridge is designed to test the strength of billet shafts, and is used only for the manufacturer of weapons. More powder charge and a special bullets designed to provide more high-pressure propellant gases during firing than conventional bullets. The same pressure is provided by live ammunition at temperatures - 60 ° C and + 70 ° C. This cartridge comes with bimetallic or steel lacquered shell.

The bullet of this cartridge consists of a bimetallic shell and lead core. It sharply differs in form and design of bullets live ammunition. The bullet has a short ogival portion and a flat vershinku. In the bottom part has a conical bullets deeper to ensure a dense prizhimaniya leadership of a bullet to the inner surface of the barrel bore. The leading portion of the bullet at a distance of about 14 mm from the bottom has the stepped transition from a diameter of 7.92 mm up to 7,58 mm. Through a long bullet cartridge has a large overall length to 5.5 mm, which excludes the possibility of loading it into established stores of weapons. The distinctive color of the bullet does not have. Cartridges early years of release may have a yellow color throughout the surface of the bullet. At the packing boxes and boxes has the inscription «High Pressure».


Cartridge enhanced charge:

«7,62-mm cartridge arr. , 1943 reinforced charge », the so -« 7,62 W obr.43 », index - 7SCH6 designed to test the strength of the locking mechanism and weapons used in the manufacture of weapons and their repairs. It creates the same pressure in the channel of the trunk, as if shooting live "ammunition at a temperature of + 70 ° C. Cartridges KM equipped piroksilinovym smokeless powder grades P-45 or P-125 and an ordinary bullet with steel core. For the differences from the live ammunition bullet Bullet KM painted with black varnish on most of the length of a bullet or to the place dultsa crimping sleeves. At the packing boxes and crates has intensified charge inscription ». Their use in the bombing is strictly prohibited. 7,62 KM Cartridges are manufactured with steel and bimetallic lacquered cartridges.

Exemplary cartridge:

For the control of the measuring means (in the ballistic tests), and ballistic weapons, as well as for the certification of the arms for excellent cartridges. The designs are similar to an ordinary cartridge with a bullet with steel core, but all parts are manufactured with greater precision (with half the limit). This ensures more stable ballistic characteristics of bullet velocity and pressure of powder gases. Vershinka bullets exemplary patron arr. 1943 painted in white. At the packing model bullets sprayed the inscription «Model».

Cartridges for throwing grenades:

Based on 7.62-mm cartridges cartridge sample of 1943 have been set up ad hoc subsidiary cartridges for throwing grenades and pistol cartridge for a special set. In 1950, Soviet Army, was adopted rifle grenade VG-45 (attached to the muzzle of the carbine SKS). The firing of rifle grenades were grenades with anti-HSV-1 rifle and fragmentation grenades VOG-1. They were throwing a grenade was carried out with the help of special blank cartridges PHS-45 (a special blank cartridge). For the throwing of grenades from a 30-mm silent under-barrel grenade launchers, small-set «Silence» on the basis of cartridge casings arr. 1943 Designer TSNIITOMASH MI Lysenko was a special patron vyshibnoy PHS-19 (a special blank cartridge). Bullet casings Dultse this cogging star. He is shorter than blank cartridges. Noiseless shooting from the grenade complex provides piston placed inside the barrel grenade launcher. In the process of shot powder gas pressure on the plunger, which, in turn, pushed the barrel of a grenade. After making the necessary momentum going grenade gas dynamic braking piston. As a result, in front of the piston comes with a minimum speed. Powder gas piston in the trunk cut off the grenade launcher and gradually fight in the air. Granata the initial velocity of about 100 m / s, providing sight range of about 300 m.


Cartridge for a special pistol complex:

Specific tasks underwater saboteurs, demanded in 1970 the creation of a special assembly tool. Based on the cartridge casings arr. 1943, was established in TSNIITOCHMASH 7.94-mm special cartridge PS1 with dowels for attaching devices to the structures created from different materials - such as steel, concrete, wood. Also at the Institute under this cartridge was developed fulgurant device. The use of specially-pistola complex SPC-1 might not only on land but under water. The complex was developed by a team of specialists within the VI Abramov, VI Zubacheva and PI Serdyukov. In 1979, he accepted to supply the Navy.

Despite the fact that it is now officially on the armament of the Russian army is 5,45 x39 mm cartridge and arms under it, the troops are a considerable number of rifles and hand guns Kalashnikov caliber 7,62 x39 mm.

According to the story the Soviets copied (stole) Winchester's spherical ball powder in 1949 to get the desired velocity at the desired chamber pressure This would correspond with the making of the first production AK-47's an SKS's. Before this time they would have either had lower velocity or higher chamber pressure. Standardizing the ammunition allowed them to calibrate the sight elevation adjustments and begin production of the rifles.

The early AK-47 415 mm barrel muzzle velocity is stated as 710 m/s.

The SKS 520 mm muzzle velocity is stated as 735 m/s.

The RPD 520 mm barrel muzzle velocity is stated as 735 m/s.

The AKM 415 mm barrel muzzle velocity is stated as 715 m/s.

The RPK 590 mm barrel muzzle velocity is stated as 745 m/s.

The Yugoslavian M70 415 mm barrel muzzle velocity is stated as 720 m/s.

The Yugoslavian M72 RPK 542 mm barrel muzzle velocity is stated as 733 m/s.

Most Yugoslavian M59/66 manuals state muzzle velocity as 735 m/ but some may show it as 740 m/s owing to the 560 mm barrel.

Czech Sa vz.58 390 mm barrel muzzle velocity stated as 705 m/s.

I was in Yugoslavia in the 1990's and heard the Chines ammunition called "underpowered". I asked why and was told it "sounded" weaker. At first I thought this might be the different powder used as H-335 sounds "louder" than most other powders. I later ran across a velocity of AK ammunition. It showed the following results.

Chinese type PS = 2230 fps

The lead core flat base bullets were developed after the boat tail steel core bullets so the lead core bullets would have a similar trajectory as the original steel core bullets.

Steel cases and steel core were chosen because of the copper and lead shortages experienced in WWII. Yugoslavia may have went to brass cases for the reason it went to a bolt hold open after last shot and an integrated 22 mm rifle grenade launcher. All of these were mandated by NATO including brass cased ammunition. Yugoslavia wasn't part of NATO but may have thought NATO had some good reasons for their mandates.

Romania and China are known to make both steel core boat tail and lead core flat base bullets. Bulgaria may also make both. The flat base bullet may tumble sooner in soft tissue but the reason for their design seems more likely to be only to follow the steel core bullets' trajectory.

Finland uses 308 bullets for it's military and loads .311" bullets for export.

The Russian use .311" bullets.

The Czechs use bullets between .308" and .311".

Some factory rated velocities.

Finland = 715 m/s.

Poland = 718 m/s @ 25 meters.

Serbia = 720 m/s in the M70 and 733 m/s in the M72 RPK.

Romania = 725 m/s.

Bulgaria = 725 m/s.

Czech Republic = 705 m/s in the Sa vz.58.

The early Soviet AK-47 ammunition was rated at 710 m/s and the later ammunition at 715 m/s in the AKM. This may reflect the difference in steel core and lead core ammunition or just a slightly improved loading.

The Chinese ammunition may be mild because it's based on the early Soviet ammunition, although China does load both types of bullets.

The original Soviet 1949 powder charge is 1.60 grams of ball powder. The early Finnish powder charge is 1.65 grams of VV N-120. The current Finnish powder charge is 1.70 grams of VV N-125. Vihtavuori was originally going offer N-125 to the public and even published load data for it. They decided not to sell N-125 because the only load data they have for it is for 7.62x39 and no other cartridge. It's between N-120 and N-130 in burning rate. It's about the most modern powder for 7.62x39.

Interesting read. I have a supply of ealry 1950's Russian ammunition in ball, tracer and API. I wondered why the vast majiority was copper washed steel cased. Very limited brass case. I guess the shortage of available metal resources was the answer. I assumed it was maybe export ammunition. Shoots well ala Chinese ammo of similar makeup.

Work on the creation of new intermediate cartridge began in the USSR only in 1943. After participants in the technical review board of the People's commissariat of armament ([NKV]) were familiarized with the captured models seized at the front in fascists, and also with the American self-loading carbine Of [m]1 given at the disposal of the USSR for the acquaintance.

The special attention of specialists drew the new German cartridge of the caliber of 7,92 mm with a length of the case of 33 mm and the developed under it carbine V 42 [of N], which underwent tests to acting army. This cartridge with a length of 48 mm had a mass of 16,2 g. with the mass of the bullet 8,2 g and the initial velocity of 700 m/s it ensured aimed fire at the distance 800 m. at the conference it was accepted the solution about the need of developing the cartridge of the reduced power for replacing the rifle cartridge in such types of weapon as self-loading (automatic) rifle and the light machine gun, and also the new types of small arms under it. On the basis of new intermediate cartridge it was possible to create light individual automatic weapon with the long range of effective shooting, than in the machine pistol. Critical for the development of new cartridge it was appointed as OKB -44 (subsequently NII-44, which in 1949. became part of NII-61 that reorganized in 1966. in [TSNIITOCHMASH]). For the definition of the optimum characteristics of cartridge the calculations according to the selection of the speed of bullet and its mass for the calibers of 5,6 mm, 6,5 mm were carried out, and 7,62 mm. these calibers were selected as most frequently being encountered in practice.

The following requirements were produced on the new domestic cartridge: case must be contemporary form - without the flange; are smaller weight and overall sizes, than in rifle cartridge; the reduced to 20% (in comparison with the rifle) power of cartridge; energy of bullet at the distance 1000 m had to be not less than 25 kgfm. Intermediate cartridge had to be used for the shooting from the automatic carbine- machine gun, the self-loading rifle and the light machine gun. Weapon under the new cartridge it had to be lung, including due to the decrease of the length of stem. It was for this purpose considered possible to use thin rifle stems for the carbine- machine guns (automatic weapons), without fearing their overheating, t to shooting of them it had to be conducted in essence by the single shots and only sometimes, at the most critical moments of battle - by automatic fire. Counting the flatness of trajectory of one of the fundamental characteristics of cartridge, in OKB -44 it was from the very beginning solved, that our cartridge must be better than German. In the cartridge of 7,92x33 point-blank range ([DPV]) was 300 m, for our were accepted BY [DPV] equal to 325 m. I already on September 3, 1943. in the technical review board [NKV] were examined two first versions of cartridge, one of them was selected (subsequently named the 7.62-mm cartridge of model 1943 g.). After September conference all weapons KB and the scientific research range of rifle and mortar armament GAU ([NIPSMVO]) began the developments of weapon under the promising automatic cartridge.

In December 1943. the first party of cartridges with the bullet with the lead core (to this cartridge they appropriated index 57- N -231) was tested on the range. After a certain modification, since March 1944. began the production of the experimental- series party of the 7.62-mm cartridges shape of 1943 g. the initial version of cartridge it had a case with the length of 41 mm and a bullet with the lead core without the rear cone and with the short head part.

The models of weapon under the new cartridge - self-loading carbine and the carbine- automatic weapon (automatic weapon) developed at that time - were intended, first of all, for the shooting the single shots. It was assumed that the automatic fire with the shooting from the automatic weapon had to be used only in the close battle (at the distance 100-200 m). Based on this, in the course of developing the cartridge shape of 1943 g. primary attention was paid to the guarantee of the shooting necessary for close grouping with the single shots, to point-blank range and to penetration effect of bullet. Of a high accuracy of shooting automatic fire from the new cartridge it was not required. However, it is later, after adoption for the armament [AK], by the basic form of shooting from the automatic weapon, for increasing the volume of fire (volume of fire - quantity of bullets to the linear meter per minute), began to count the fire by bursts, independent of ranges to target. In this case, for the sake of fairness, it is necessary to note that the probability of hit into the purpose with the fire by bursts rose, but insignificantly, while the expenditure of cartridges grew proportional long burst.


In 1944 ; after obtaining of the first results of tests, began work on the improvement of cartridge for the purpose of an increase in its close grouping and susceptibility to breakdown. The head (ogival) part of the bullet was elongated, which made possible to improve ballistic coefficient with mass conservation of bullet. In bullet was introduced rear cone, which decreased air resistance to the flight of bullet, moreover not only, as then it was counted, at subsonic speeds (i.e. with the shooting to the long range), but also with the supersonic flight speeds of bullet. For retaining the overall length of cartridge the cartridge case neck was shortened on 2 mm and increased the depth of landing bullet in the case. Case obtained the final length of 38,7 mm (during the designation of the cartridge of 7,62x39 the length of case it is indicated roundedly). The work on the replacement of lead core by steel began after this. Bullet with the steel core obtained designation - “substituted”. Its length increased with 22,8 mm, in the first version, to 26,8 mm. the basic argument of the application of low-carbon steel for the core was not so much an increase in the penetration effect of bullet, as savings of scarce lead (to 50%) and technological effectiveness of stamping core. By the way the technology of its production was borrowed in cartridge TT. Here it should be noted that at that time the basic standard of the penetration effect of bullet was the estimation of the possibility of the penetration of steel army helmet at the distance 800 - 1000 m. to the middle 1947 g. all noted during the tests deficiencies on the cartridge shape of 1943 g. with the usual bullet were removed, and GAU made a decision about the production of a series of cartridges and prototypes of weapon for the troop tests.


For the purpose of an increase in the tactical possibilities of promising weapon, and also on the basis of the experience of the creation of the 7.62-mm rifle cartridges of different designation, together with the cartridge with the usual bullet, was carried out the development of the cartridges shape of 1943 g. with the special bullets: armor-piercing incendiary (it is developed in 1944.), igniting and tracing (they are developed in 1948.). In 1949. simultaneously with the Kalashnikov automatic rifle for the armament of the Soviet Army were accepted the 7.62-mm cartridges shape of 1943 g. with the enumerated types of bullets. Subsequently the improvement of the cartridge shape of 1943 g. with the usual bullet with the steel core was conducted in the direction of an increase in the penetration effect of bullet (for guaranteeing the defeat of personnel in the means of individual armor protection), and tracing, in the direction of an increase in the period of combustion of tracer and time dilation of the initiation of its combustion. In the improvement of cartridges the great significance had use as the charges of new powders of spherical granulating. As is known, the priority of the creation of powder of spherical granulating belongs to the USA. Its basic merit - high [graviometricheskaya] density (density of filling of case) - the order of 0,85 [g]/[sm]3, the increased progressiveness of combustion and high technical ease of manufacture. This allows, with the equal powder chamber, to ensure high muzzle energy to bullet or, with the equal muzzle energy, to decrease the overall sizes of case.



Initially cartridge was produced only with the bimetallic case - steel plated by pinchbeck. But in 1948 ; because of the difficulties with obtaining of the bimetal, whose major portion before was supplied from the USA on the lend-lease, the case of automatic cartridge they became to make from that brass-coated they began. The process of brass plating, borrowed in German industry, was connected with the use of the strong poisonous substances. Therefore with the mastery of the production of bimetal in the USSR since 1952. automatic cases again began to be made from this material. Subsequently, at the beginning 1960- X yr., in the number of enterprises was mastered production and the steel varnished case (with the varnishing of green color), which ensured the considerable savings of pinchbeck. Already the production of steel case with the polymeric coating (water solution) is mastered in our time, which considerably decreased the harmfulness of production.

The live cartridges:

Cartridges with the usual bullet “7.62-mm cartridge shape of 1943 g. with the bullet with the steel core PS” (PS - bullet “substituted”; subsequently they began to use term - “bullet with the steel core”), conditional designation - “7,62 PS”, it was intended for destruction of the living of the targets, situated opened or after the easy shelters, fire means and the unarmored technology. Initially this cartridge with the bimetallic case had an index - 57- N -231[S]. Appeared at the beginning 1960- X cartridge with the steel varnished case obtained index - 57- N -231[SL]. But in the course of time they calculated by inadvisable to indicate the material of case in the index of cartridge, and all cartridges with the bullet with the steel core obtained united index - 57- N -231. Usual bullet consists of the steel shell, plated from both sides by the layer of pinchbeck, steel stamped core made of low-carbon steel of stamp 10 and lead jacket. In the middle part of the bullet is executed the annular rolling, into which is pressed the cartridge case neck during assembling of cartridge. In 1960- e yr. was prepared and tested the test batch of cartridges with the bullets PS, whose steel shell instead of the pinchbeck was covered with green varnish. the 7.62-mm cartridges of model 1943 g. with the bullet PS of the different years of release bullet with the [netermouprochnennym] core broke through steel helmet at the distance 900 m and fragmentproof bulletproof vest at the distance 600 m. of distinctive painting the bullet of this cartridge it does not have.

Since 1962. cartridge case neck on the joint with the bullet and the edge of percussion cap for the increase hydrostability are covered with varnish- hermetic seal. In 1962 - 1963 yr. the color of varnish was violet, and since 1964. varnish on the cartridges with any type of bullet became red. Since 1984 ; when instead of the rifle pyro powder they began to use powder of spherical granulating, on the tail end of the bullet was executed the ledge for facilitating [patronirovaniya]. Ledge removed the entry of the small grains between the walls of cartridge neck and the bullet. Distinctive painting the bullet of these cartridges also does not have.

Long time a question of the technological effectiveness of the production of cartridges prevailed above a possible increase in the penetration effect of bullet - as is known, it is ensured in essence by material and form of core. In particular, hardening core was not allowed, but its form was determined by the labor expense for stamping. Nevertheless the wide acceptance of the means of individual armor protection, which ensured protection from the bullets with the steel core made of low-carbon steel, required the improvement of cartridges. Since 1989 ; for increasing the penetration effect of bullets they began to use the thermally-strengthened core of the increased hardness. It make made of high-carbon leaf-spring steel of the stamps of 65[G], 70, 75 with the subsequent heat working. The penetration effect of bullets with the new core on the solid obstacles increased 1,5-2. Bullet with the thermally-strengthened core ensures the penetration of steel helmet at the distance 1000 m; fragmentproof bulletproof vest at the distance 700 m and the bulletproof bulletproof vest, which protects from the automatic bullets with the [netermouprochnen]- core, at the distance 100 m. of distinctive painting the bullet of this cartridge also does not have. From the cartridges with the [netermo]- reinforced core new cartridge can be distinguished only by the year of release.


Cartridges with the tracer bullet:

“7.62-mm cartridge shape of 1943 g. with the tracer bullet T -45”, conditional designation - “7,62 T -45”, index - 57- T -231[P], are intended for aim designation and fire adjustment at altthe firing distances to 800 m, and also for the defeat of personnel. Cartridge is produced with that bimetallic or steel varnished by cases. In the period from 1949 until 1951. inclusively cartridge was made with the brass-coated case.

In the bimetallic shell of tracer bullet, in its head part, the core from the lead- antimonous alloy is pressed. Behind the core is placed plated by pinchbeck steel cup with the pyrotechnic composition (ignition, transitional and tracing) pressed in it. To avoid the damage of tracer composition bullet T -45 does not have a rolling. In the ground part of the bullet the ringlet is fixed, it fulfills the role of nozzle and ensures the uniform expiration of the products of combustion of tracer composition.

With the shot the combustion from the powder charge is transferred to ignition composition. After the departure of bullet from the bore the combustion from the ignition composition is transferred to transitional and then tracer composition. Burning, tracer gives the bright luminous track of red color, well seen with day and at night. With the entry into the inflammable objects the bullet is capable of setting on fire them. In 1973. the tracer cartridge was modernized. A change of constructing the bullet made it possible to increase the volume of the powder chamber, which facilitated the selection of charge on the different parties of powder Of [vUfl], to ensure the stability of ballistic data and to obtain the reliable work of weapon.

This modernization of the tracer cartridge conducted the colleagues OF [TSNIITOCHMASH] - [V].[M]. Sabelnikov (leader), [P].[S]. Korolev [A].[T]. Of [khomyakova]. At the end the 1990's the engineers OF [TSNIITOCHMASH] [L].[I]. Of [novozhilovoy] and the like Of [vasilevoy] carried out the modernization of the tracer of bullet T -45. New cartridge obtained complete designation - “7.62-mm cartridge shape of 1943 g. with the modernized tracer bullet T -45[m]”. It was accepted for the armament in 2002. under the index 57- T -231[PM]1. Modernization made it possible to increase the distance of tracing to 850 m and ensured the initiation of the combustion of tracer composition 50- 120 m of the muzzle end face. This delay of the combustion of tracer makes it possible to better disguise firing position pointer and ensures continuous battlefield surveillance through the night sights with the image converters. [Vershinka] of the bullets of all tracer cartridges is painted into the green colored they are encountered cartridges with the tracer bullet, prepared at the beginning 1960- X the yr., which do not have painting, but with [germetizatrom] of green color in cartridge case neck and on the edge of percussion cap.

Cartridge with the armor-piercing incendiary bullet:

“7.62-mm cartridge shape of 1943 g. with the armor-piercing incendiary bullet [BZ]”, conditional designation - “7,62 [BZ]”, index - 57-[BZ]-231, are intended for the defeat of the lightly armored altof targets, ignition of fuel, which is found beyond the armor or in the thick-walled container; and for the defeat of personnel, which is found beyond the light armor covers on the distance to 300 m.

Cartridge was produced with the brass-coated or bimetallic case. Armor-piercing incendiary bullet consists of steel, plated by the pinchbeck of shell with the tombac tip, the steel heat-treated core with the lead jacket also of igniting compound, which is located in the lead pan. With the impact of bullet against armor lead pan, moving by the inertia forward, compresses igniting compound and thus sets on fire it. Flame, through the opening, pierced by steel core, penetrates the space behind the armor and it is capable of setting on fire fuel.

Armor-piercing incendiary bullet breaks through steel helmet at the distance 1100 m and fragmentproof bulletproof vest at the distance 1000 m. the sheet of the armor with a thickness of 7 mm breaks through at the distance 200 m. Of [vershinka] of bullet it is painted in the black color with the red belt. On the pasteboard bundles, the metallic boxes and the wooden boxes with the cartridges [BZ] is brought inclined black- red strip.

Cartridge with the incendiary bullet:

“7.62-mm cartridge shape of 1943 g with incendiary bullet 3”, conditional designation - “7,62 Oe”, index - 57-3-231, are intended for igniting the flammable liquids (gasoline, kerosene) in the steel tanks with the walls with a thickness of up to 3 mm, and also easily being caught fire materials (dry grass, straw and other) at the distances to 700 m. on their construction and action bullet “7,62 Oe”, it relates to the type of incendiary bullets with the pyrotechnic igniting compound and is igniting- tracer, ensuring observation of the results of shooting at the well visible (to 700 m in the daytime and at night) route of red color. Cartridge was produced with the brass-coated or bimetallic case. Bullet consists of altsteel, plated by pinchbeck, shell with the tombac tip, igniting compound, which is located in the head part of the bullet, core from low-carbon steel, jacket from the lead-antimony alloy, the bimetallic cup with the pyrotechnic composition (ignition, transitional and tracing) and the ringlet (its designation the same as in other tracer cartridges).

Sharp ram compression and heating of igniting compound occurs with the impact of bullet against solid obstacle, by the being advanced steel core, as a result of which igniting compound is set on fire. The tip of bullet is mashed, shell is developed, and flame from the igniting compound ensures the ignition of purpose. With the encounter with the obstacles of low density, because of the low sensitivity of bullet, the igniting compound can and not be set on fire. There exists two modifications of bullet with different radius of ogive. Sharper acute, appear later, to a lesser degree differ from the trajectory of bullet PS. [Vershinka] of the bullet of cartridge “7,62 Oe” is painted into the red colored on the pasteboard bundles, the metallic boxes and the wooden boxes with the igniting cartridges it is brought inclined red strip. Cartridges with the armor-piercing incendiary and incendiary bullets were collected they by hand and had high cost. To use them it was planned only in the period of military operations. These cartridges, as a rule, were not used for the practice firings. Were after accumulated sufficient reserves of cartridges with the bullet [BZ] and 3, their production was ended. At present cartridges with the armor-piercing incendiary and incendiary bullets from production are removed, but they can be encountered in the army reserves.

Cartridge with the bullet with the reduced speed:

In the middle 1950- X for equipping of reconnaissance and intelligence and sabotage subdivisions and guarantee of concealed destruction of the unprotected living targets at altthe distance to 400 m it was developed and in 1962. it is accepted to the armament “7.62-mm cartridge with the reduced speed of bullet US”, the conditional designation - “7,62 US”, the index - 57- N -231[U]. This cartridge is intended for the shooting from the automatic weapons [AK] ([AKS], [AKM], [AKMS], [AK]-103 and [AK]-104) with the instruments for the noiseless and flameless shooting [PBS] or [PBS]-1. Cartridge with the bullet US together with the instruments [PBS] and [PBS]-1 was developed in NII-61 by the engineers OF [N].[M]. [Elizarovym] (the chief designer of department, the designer of complex), BY [B].[V]. [Seminym] (cartridge), [K].[V]. [Smekaevym] (cartridge), [L].[I]. by Golubyov (muffler), [M].[E]. by Fedorov and [M].[A]. Of [kuzminoy]. Cartridge is produced with that bimetallic or steel varnished by cases. An increase in the mass of the bullet (it is 12,5 d) for the purpose of conservation of energy was achieved due to an increase in its length of -33,62 mm (length of the bullet of the cartridge 7,62 PS of -26,8 mm). The guarantee of the necessary penetration effect was achieved by the application of a core made of the tool steel [U]12[A], located in the head part of the bullet. The lead core, located after it, provides not only the necessary mass, but fulfills the role of jacket. The selected diameter of bullet -7,94 mm (all remaining bullets have diameter it is 7,92 mm) - ensures the dense fitting of bullet into the threads and the necessary pressure of solid-reactant gases in the bore. The bullet, which obtains the subsonic initial velocity, does not create ballistic wave in the trajectory, but muffler ([PBS]) reduces the exhaust gas velocity from the muzzle part of the stem. Bullet US is capable of opening steel helmet at the distance to 400 m and fragmentproof bulletproof vest at the distance 75 m. painting bullet - black [vershinka] with the green belt. Inclined black- green strip is brought on the pasteboard bundles, the metallic boxes and the wooden boxes with the cartridges US.


Cartridge with the armor-piercing bullet:

Creation into 1980 - the 1990's relative to light bulletproof bulletproof vests with the high level of protection and saturation by them of the subdivisions of ground forces of many armies altof peace led to the need of improving the cartridge with the usual bullet. The 1990's this modernization was at the end carried out on the Barnaul Machine Tool Building Plant [D].[I]. Veronese and BY [V].[V]. [Zakharyashchevym]. In the course of modernization changes underwent the form, material (instead of low-carbon steel, they began to use tool steel [U]12[A]) and process of heat treating the core. As a result bullet became armor-piercing. New cartridge was accepted for the armament in 2002. and were obtained designation - “7.62-mm cartridge of model 1943 g. with the armor-piercing bullet [BP]”, conditional designation - “7,62 [BP]”, index - 7[N]23. New cartridge is intended for destruction of living of targets in the means of the individual armor protection (located opened or after the easy shelters), the fire means and unarmored technology. The device of the bullet of the cartridge of 7[N]23 is analogous (with exception of core) with cartridge with the bullet with the steel core 7,62 PS. Case of cartridge - steel varnished. New cartridge more than three times exceeded on the susceptibility to breakdown of solid obstacles, the cartridge with the bullet PS. At the distance 200 m the armor-piercing core of the bullet of new cartridge breaks through 5- mm armor plate of the stamp of 2[P], while on 250 m a bulletproof bulletproof vest of the type of 6[B]5. In this case is provide ford [sopryagaemost] of the trajectory of the bullet of new cartridge with the bullet with the steel core. Painting bullet - black [vershinka].

Cartridge with the bullet with the lowered ricocheting ability:

In 2002 - 2003 yr. for the subdivisions MVD RF was developed a number of the cartridges (9x18, 9x19, 5,45x39, 7,62x39 and 7,62x54R) of those equipped with bullets with the lowered ricocheting altability (PRS). In contrast to the usual bullets of the type PS ([PST], [LPS]), in the bullets of the type PRS is absent steel core. The need of creating the special cartridges of this type is connected with the special features of the tactics of the application of the special subdivisions MVD, the large part of military operations or special operations of which is conducted in the populated areas. In this case the fire from the small arms is conducted on the small distances. In such situations the high initial velocity of usual bullets with the steel core leads to the large number of ricochets from the walls of buildings, concrete fences, road surface and this the like creates the real threat of injury of its personnel. However, bullets of the type PRS with the entry into the solid obstacles are mashed, they rapidly stall and do not give this quantity of dangerous ricochets as bullets with the steel core.

The blank cartridge:

For the imitation of the sound of shot in the course of the instruction of [strelkov], and also for the work of salutes is used the blank cartridge. Together with the bushing for the unmarried shooting, altscrewed to the muzzle part of the stem of automatic weapon or light machine gun and by that making it possible to create the necessary pressure of solid-reactant gases in the stem, blank cartridge it ensures the work of the moving elements of the automation of weapon. Blank cartridge and muzzle device (bushing for the unmarried shooting) were developed by the designer NII-61 OF [E].[T]. [Rozanovym] in 1949. Cartridge obtained complete designation - “7.62-mm blank cartridge shape of 1943 g.”, conditional designation - “7,62 unmarried shapes 43” and index - 57- X -231. Blank cartridges are produced with that bimetallic or steel varnished by cases. The blank cartridges, prepared in 1949 -1951 yr., have the steel brass-coated case. Blank cartridge differs from combat in terms of the absence of bullet and in terms of the elongated cartridge case neck. Cartridge case neck is pressed by asterisk and is covered with the layer of the sealing varnish of violet or red color. Powder charge consists of 0,73 g of porous pistol powder of stamp P -125. The blank cartridge shape of 1943 g. is shorter than combat, its length is 48,2 mm. with the shot from the friction primer it is set on fire powder charge and from the created pressure it is unclenched the asterisk of pressed cartridge neck. Shot is accompanied by characteristic sound, flash of flame and by smoke.


The drill cartridge:

For the instruction in the methods of the loading of weapon, carrying out of shot and equipment of stores the drill cartridge is used. Its complete designation - “7.62-mm drill cartridge altshape of 1943 g.”, conditional - “7,62 [UCH] of [obr].43” and index - 57- N -231[uch]. Cartridge is executed with the use of basic components of cartridge with the usual bullet with the steel core 7,62 PS, but it does not contain powder charge and has the castrated friction primer or brass cap from the friction primer. Cartridge is produced with the bimetallic or steel varnished case. An increase in strength of fastening bullet in the cartridge case neck, to avoid its precipitation in the course of trainings on the loading of weapon, is ensured by the additional pressing of cartridge neck on the bullet. The bullet of the drill cartridge of distinctive painting does not have, but four symmetrically located longitudinal extrusions are executed on the case of cartridge.

Cartridge of the high pressure:

The cartridge of high pressure, complete designation - “7.62-mm cartridge shape 1943 g. of high pressure”, conditional - “7,62 vd shape 43” and index - 57- N -231 [v], were developed in NII (Scientific Research Institute) alt61 (the chief designer OF [K].[V]. Of [smekaev]). Cartridge vd is intended for checking the strength of billets it is trunk it is used only at the plants the producers of weapon. Larger powder charge and special construction of bullet ensure the higher pressure of solid-reactant gases, than with the shooting usual cartridge. The same pressure is ensured by live cartridges at temperatures - 60°[S] and + 700[S]. This cartridge is produced with the bimetallic or steel varnished case.


The bullet of this cartridge consists of bimetallic shell and lead core. It sharply differs in the form and the construction from the bullets of live cartridges. Bullet has short ogive and flat [vershinku]. In the ground part of the bullet is a conical deepening for guaranteeing the dense pressing of the leading part of the bullet to the internal canal surface of stem. The leading part of the bullet at a distance about 14 mm of the bottom has stepped passage from the diameter 7,92 mm of [d]o 7,58 mm. due to the longer bullet cartridge it has large overall length on 5,5 mm, which excludes the possibility of its loading into the regular stores of weapon. Bullet does not have distinctive painting. The cartridges of the early years of release can have the yellow painting of the entire surface of bullet. On the packing boxes and the boxes there is an inscription “high pressure”.


Cartridge with the heavy charge:

“7.62-mm cartridge shape of 1943 g. with the heavy charge”, conditional designation - “7,62 Oe [obr].43”, index - 7[Shch]6 are intended for checking the strength of the locking device altof weapon and is used with the production of weapon and its innovation repair. It creates the same pressure in the bore, as with the shooting combat “cartridges at a temperature + of 70°[S]. cartridges UZ are equipped with smokeless pyro powder of stamps P -45 or P -125 and with usual bullet with the steel core. For the difference from the live cartridges the bullet of cartridge UZ is colored with japan to the large part of the length of bullet or to the place of the pressing of cartridge case neck. On the packing boxes and the boxes there is an inscription heavy charge”. Their application in the course of shootings is categorically forbidden. Cartridges 7,62 knots are produced with that bimetallic and steel varnished by cases.

Model cartridge:

For the inspection of measuring means (in the course of ballistic tests) and ballistic weapon, and model cartridges also for the certification of this weapon are developed. altIn their construction they are analogous to cartridge with the usual bullet with the steel core, but all their parts are made with the larger accuracy (with the half admittances). This ensures more stable ballistic data on the speed of bullet and the pressure of solid-reactant gases. [Vershinka] of the bullet of the model cartridge shape of 1943 g is colored into the white of colored on the packing model cartridges it is brought inscription “model”.

Cartridges for the throwing of the grenades:

On the basis of the case of the 7.62-mm cartridge of model 1943 were created special auxiliary cartridges for the throwing garnet and cartridge for the special pistol complex. In 1950. for the armament of the Soviet Army was accepted the rifle grenade launcher [VG]-45 (it was fastened to the muzzle part of the carbine [SKS]). Shooting from the grenade launcher was conducted by rifle anti-tank [VPG]-1 and rifle fragmentation grenades [VOG]-1. Their throwing from the grenade launcher was achieved with the aid of the special blank cartridges [PKHS]-45 (cartridge unmarried special). For the throwing of grenades from 30- mm of the noiseless [podstvolnogo] grenade launcher of the pointer-in- grenade-throwing complex “of Tishin” on the basis of the case of the cartridge shape of 1943 g. the designer OF [TSNIITOMASH] [M].[I]. of Lysenko created special knock-out cartridge [PKHS]-19 (cartridge unmarried special). The cartridge case neck of this cartridge is pressed by [zvezdkoy]. It is shorter than the blank cartridge. The noiselessness of shooting from the grenade-throwing complex was ensured by the piston, placed inside the stem of grenade launcher. In the process of shot the solid-reactant gases pressed to the piston, which, in turn, pushed out grenade of the stem. After giving of the necessary pulse to grenade gas-dynamic braking of piston occurred. As a result to the front position piston came with the minimum speed. Solid-reactant gases were intercepted by piston in the stem of grenade launcher and gradually were removed into the atmosphere. Grenade obtained the initial velocity of approximately 100 m/s, the ensured sighting range of shooting of approximately 300 m.

Cartridge for the special pistol complex:

The specific tasks, solved by underwater saboteurs, required in 1970- X of the creation of special erecting tool. On the basis of the case of the cartridge shape of 1943 g. in alt[TSNIITOCHMASH] was created with 7,94- mm special cartridge [PS]1 with the dowel for fastening of special devices to the constructions, created from different materials - for example steel, concrete, tree. So in the institute under this cartridge there was developed shooting device. Application of a special- pistol complex [SPK]-1 not possible only on dry land, but also under water. Complex was developed by the group of specialists in the composition [V].[I]. of Abramov, [V].[I]. Of [zubacheva] and [P].[I]. Of [serdyukova]. In 1979. it is accepted to the supply the Navies.

They started under the 7.62-mm automatic cartridges shape of 1943 g. in different years in the USSR and Russia for the armament: - the light machine gun of Degtarev (RPD) 1944 g.; - the self-loading carbine of Simonov ([SKS]) 1949 g.; - the Kalashnikov automatic rifle ([AK]) of 1949 g. and its modification with the folding metallic butt ([AKS]), with the night sights [NAP]-1 and [NSP]-2 ([AKN], [AKSN]), with the instrument for the noiseless and flameless shooting [PBS]; - the lightened Kalashnikov automatic rifles ([AK] and [AKS]) and of their modification with the adaptation for the noiseless and flameless shooting [PBS] and with the night sight [NSP]-2 ([AKN], [AKSN]); - the modernized Kalashnikov automatic rifle (AKM) and its modification with the night sight [NSP]-2, modification AKM with the night sights [NSP]-3, [NSPU] and [NSPUM] (AKMH, AKMH1 and AKMH2), with the folding metallic butt (AKMC) and its modification with the night sights ([AKMSL] and [AKMSL]-1), with the instrument for the noiseless and flameless shooting [PBS]-1, with [PBS]-1 and noiseless under- barrel grenade launcher (“Tishin's complex”); - the light machine gun of the Kalashnikov (RPK) of 1959, its versions with the night sights ([RPKN] and [RPKN]2), version with folded by butt ([RPKS]) 1962 g. and its modification with the folding butt and the sight of night vision [NSP]-2 ([RPKSN]) and with the folding butt and the sight of the night vision [NSP]-3 ([RPKSL]) of 1967 g.; - Kalashnikov automatic rifle [AK]103 and its modification with the night sight [AK]103[NZ]; - Kalashnikov automatic rifle small [AK]104 and its modification with the night sight [AK]104[NZ].

World War II with a sufficient clarity showed that the armament of army must ensure the maximum maneuverability of the troops, i.e. must be lung and compact. At the same time the need of further increase in the power of the fire of infantry appeared, since with saturation of the armies of belligerents by mechanized weapons most stressed combat for the infantry are developed on the short distances and flow very transiently. Infantry must for the short time interval ensure the maximum power of fire, since during this period it always cannot design for support to the artillery and of other powerful fire means. Attempts at the creation of automatic rifles and light light machine guns under the existing rifle cartridge showed that without worsening in the combat and operating characteristics to create the models satisfying army is not presented by possible as a result of the large overall size and power of rifle cartridge. The received universal acclaim in the period of war machine pistol made it possible to successfully solve a number of the fire missions, confronting infantry, since it possessed a comparatively small mass and developed very powerful fire. However, effective distance from this type of weapon did not exceed 200-300 m. in connection with this it arose a question about the creation of the new cartridge, which on the ballistic data, the mass and the overall sizes occupies the intermediate position between the rifle and pistol cartridges. This cartridge because of the best closely grouped fire and piercing power of bullet ensures effective fire at the considerably long range in comparison with the pistol cartridge. In comparison with the rifle cartridge intermediate cartridge is less powerful. However, the fire of small arms 7.62- mm of caliber, with exception of heavy machine guns, adapted to the distance not more than 600-800 m. on this distance of the bullet of intermediate cartridge they break through three pine boards with the thickness of 2.25 cm they, i.e., possess energy approximately 196 George (20 kgfm), which is completely sufficient for the breakdown of personnel. Rifle cartridges were developed on the basis of the lethal force of bullet at the distances of more than 2000 m. since in the progress of combat fire from the small arms at this distance it was not conducted even from the heavy machine guns, it became obvious, that the rifle cartridges possess superfluous power. Furthermore, the large recoil momentum of rifle cartridge created definite difficulties in finalizing of the light individual automatic weapon of soldier, which ensures high efficiency with the shooting from the hand, from the elbow, costing and in the motion. Intermediate cartridge with the smaller recoil momentum with a sufficient range of effective fire made it possible to decrease the mass of weapon and [nosimykh] ammunition.

Work on the creation of intermediate cartridge in our country began still in 1939 ; although a question about this, as noted, was placed considerably earlier. For investigating the question the cartridge of the caliber of 5.45 mm was developed and task for the design of self-loading rifle under this cartridge was given. However, in connection with the military actions designers were switched to the more urgent actual works. Work on the creation of light carbine under the pistol cartridge was ended also, despite the fact that this type the carbines of the construction of Simonov, [S].[A]. of Korovin and Degtarev showed not bad results.

The development of the intermediate cartridge of [bsha] is again begun in 1943. In this case before the designers the task with the caliber of 7.62 mm of ensuring kinetic energy of bullet to distance 1000 m on the order of 196 George (20 kgfm) with the length of stem 500-520 mm was set and with the mass of the cartridge 15-17 g. as a result of this work to the most fully satisfying operational requirements was acknowledged the cartridge, designed BY [N].[M]. [Elizarovym] and [B].[V]. [Seminym], which was accepted for the armament under the designation of the cartridge shape of 1943 g. substantial aid to designers with the creation of new cartridge they showed the workers of the plants of defense industry [P].[V]. Riazanov, [S].[D]. Orekhov, [I].[T]. Melnikov, [V].[N]. Of [baskleev] and GAU - [N].[N]. [Dubovitskiy], [A].[N]. Sergeyev, [A].[R]. Of [emets], [A].[YA]. Of [bashmarin] and [I].[YA]. [Litichevskiy].

The test batch of the new carbines of Simonov (CKC-45) is past combat tests in the forces of the 1st Belorussian front - sole example of the application of a cartridge shape of 1943 g. in the World War II.

Depending on the conditions for combat employment the cartridge shape of 1943 g. can be used with the usual, tracer, armor-piercing incendiary or incendiary bullet.

Usual bullet is intended for the defeat of live enemy target. It consists of steel that plated by the pinchbeck of shell, lead jacket and steel stamped core. Soft lead jacket makes possible for bullet comparatively easy to cut into the threads. Shell ensures the necessary strength of bullet, its reliable conducting on the threads, and steel core together with the savings of lead makes the bullet of low-sensitivity to the deformation and increases penetration effect with the shooting at the durable obstacles. In the middle part the bullet has the ring groove (rolling), where cartridge case neck for purposes of the durable fastening of bullet in the case is pressed. Tail section of the bullet - conical, for decreasing air resistance in flight.

Tracer bullet serves for the correction of fire, aim designation, signaling and destruction of living of targets. It consists of steel that plated by the pinchbeck of shell, lead core, steel plated by the pinchbeck of cup and ringlet. The tracer and ignition compositions are pressed in the cup. Ignition composition is set on fire by solid-reactant gases during the motion of bullet along the bore. For an improvement in ignition conditions its surface is made by relief. With the combustion of ignition composition it sets on fire the tracer composition, whose combustion is accompanied by the formation of the red flame, which makes it possible to control the flight at any time of twenty-four hours. Ringlet makes it possible to have the identical diameter of outlet in different bullets and its concentric arrangement relative to longitudinal axis. With entry into the inflammable objects (straw roof, dry grass and others) the tracer bullet is capable of setting on fire them.

Armor-piercing incendiary bullet is intended for the ignition of fuel (gasoline) and destruction of targets, which are located beyond the thin armor shelters. It consists of steel that plated by the pinchbeck of shell, tombac tip, steel hardened armor-piercing core, lead jacket and lead pan with the igniting compound. The motion of armor-piercing core sharply is impeded with the impact of bullet into the solid obstacle. Lead pan, moving by the inertia forward, compresses igniting compound and by this its ignition is caused. The decomposition products of igniting compound, penetrating following the core the formed hole, are capable of setting on fire the fuel, located after the armor.

Incendiary bullet ensures the ignition of fuel (gasoline), which is located in the metallic capacities with the wall thickness to 3 mm, and also straw roofs, stacks of hay, dry grass. On the device and the action this bullet is igniting- tracer, it gives good, seen with day and at night, red route. It consists of steel that plated by the pinchbeck of shell, tombac tip, steel core, lead jacket, steel plated by the pinchbeck of cup with the tracer and ignition compositions also of igniting compound. The motion of bullet is impeded with the impact into the obstacle, in this case the core, moving by the inertia, compresses igniting compound and by this its ignition and destruction of tip and shell are caused. The inflammable objects ignite by the decomposition products of igniting compound, which have high temperature. If core breaks through obstacle, then the part of igniting compound is passed after the core into the hole and it can set on fire combustible substances after the obstacle. In all cases the igniting action of bullet is strengthened by the burning tracer composition, if it yet did not burn up to the moment of the encounter of bullet with target.

The tracer, armor-piercing incendiary and incendiary bullets are designated respectively to T -45, [BZ] and 3.

The adoption of the cartridge shape of 1943 g. opened new prospects in the construction of automatic weapon. The absence of flange simplified the construction of feed mechanism. The not very strong return of cartridge made it possible to considerably increase the accuracy of shooting. Under the cartridge shape of 1943 g. were developed the self-loading carbine of Simonov [SKS], Kalashnikov automatic rifle [AK], light machine gun of Degtarev RPD and light machine guns of Kalashnikov RPK and [RPKS].

Bullets: 1 shell; it is 2nd lead jacket; 3- steel core; 4 lead core; cup is 5th; 6 tracer composition; 7 tip (tombac); igniting compound is eighth; 9 lead pan.

The cartridges of 7.62[kh]39 are produced with the usual bullets and with the special-purpose bullets: tracing and armor-piercing incendiary.

* With the usual bullet PS - bullet with the steel core (a), m=7,9 g, consists of the steel, covered with pinchbeck shell and steel core, between which there is a lead jacket.
* With the tracer bullet T -45 - (b), is intended for aim designation and correction of fire at the distances to 800 m, m=? g, the head part of the shell is painted into the green colored it consists of shell, lead core and cup with the pressed tracer composition.
* With the armor-piercing incendiary bullet [BZ] - (c), m=? g, is intended for the ignition of flammable liquids and for the defeat of live enemy target, which is found beyond the light armor covers, at the distances to 300 m. it consists of shell with the tombac tip, steel core with the lead jacket, lead pan and igniting compound. The head part of the shell is painted in the black color with the red belt.
* With the incendiary bullet - painting the apex of the bullet of red color.
* With the bullet of reduced speed US - painting the apex of bullet is black with the green belt.
* Standard cartridge [EP] - painting the apex of the bullet of white color.
* Cartridge with the heavy charge UZ - entire bullet of black color.
* The cartridge of high pressure vd - distinctive painting does not have, on the ammunition box inscription “high pressure”, case lid from the 2nd sides from the lath to the edge is painted into the yellow colored.

The cartridges shape 1943 are stoppered into the wooden boxes. In the box two hermetically sealed metallic boxes on 660 cartridges in each are plotted; cartridges in the boxes are packed into the pasteboard bundles on 20 cartridges in each. In all in the box are placed 1320 cartridges. On side walls of the boxes, in which are stoppered the cartridges with the special bullets, are substituted the colored strips, which correspond to painting the head parts of the bullets.

“The soldiers of the success”

7.62- mm the cartridge of model 1943, appeared already in the course of World War II and it became as if answer to the German development program of the cartridge of 7.92[kh]33 to the automatic carbine. Its finalizing was completed only by 1949, when the cartridge of 7.62[kh]39 accepted its present form. Paradox, but the cartridge, developed in 1943, substantially (even along the length case) differs from that, which is called “model 1943”. Apparently, these are the intrigues of [sekretchikov]. Without suspecting about this incident, by this cartridge completely successfully shoots as the minimum half of peace. Moreover, the construction of cartridge proved to be so grow prettier that it barely changed to this day: only for increasing the armor-piercing ability the core of bullet PS now is thermoed-strengthen, and the bullets, intended for the equipment of cartridges with the powder of spherical granulating, have on the ground part a ledge for facilitating [patronirovaniya]. The small modifications of technological order underwent tracer bullet T -45. For the shooting from the automatic weapon with the instrument of noiseless shooting the cartridge with the reduced speed of bullet is produced (US). But for the throwing of grenades of 30- mm of [podstvolnogo] grenade launcher is made special cartridge with the standard case with the cartridge neck pressed into the star somewhat shorter than the unmarried. Armor-piercing incendiary and incendiary bullets from production are removed. This position on no account testifies about the absence of the works on the cartridge. After is half a century developed and is tested the large number of its modifications up to the exotic two-field rotation and with the aluminum case. But they do not burn into the mass production. Yes even with the advent of the [maloimpulsnogo] cartridge of the caliber of 5.45 mm its production was considerably reduced.
