A couple of days ago I found a nice piece of BLM land to really stretch the legs of my NDM-86/1P21 combo. I picked out a likely-looking light-colored spot (appx 4' wide & 3' tall) on a hillside and ranged it w/my LRF by walking most of the way out and ranging to both the hillside and back to my car (which is an excellent laser reflector). Range came to be 1,280m from my car to the spot I picked out so I set up 80m closer towards the target to make my range 1,200m.
Now, previous experience w/the 1P21 & Georgia Arms 168gr match sighted in at 500m showed a need to hold low at longer ranges due to the trajectory difference between the 1P21's 7.62x54 BDC & .308 168gr match ammo. I guesstimated I'd need to back off appx 50m to hit dead-on with the extreme range chevron's on the 1P21's reticle (meant for 1,000m, 1,100m, 1,200m & 1,300m shooting). So, instead of setting the reticle to 900m/9x I set it to 850m/8.5x and held dead-on.
I hit low, a few feet below my aiming point (?). I reset the reticle to 900m/9x and tried again and hit dead-on at 1,200m! I fired another 8rds and all either hit or missed slightly to the left (very slight breeze but at 1,200m it has lots of time to work on a bullet in flight).
I'm very pleased that the NDM-86/1P21 combo can hit that far out (right at 3/4 of a mile, furthest distance I've ever shot at) but that's pushing the reticle to its limit as at 9x magnification I can barely make out & use the 1,200m chevron, the 1,300m chevron can't be seen at all. At 1,200m I'd say the NDM-86/1P21 combo is definitely a threat but not deadly (further practice/testing at that range may change that impression).
As for why the 1,200m chevron is dead-on when I was expecting it to be off by 50m or so I don't have an exact answer. Perhaps the trajectories re-coincide at 1,200m or perhaps my removing then remounting the 1P21 has thrown my elevation off just a bit (I'll have to re-test the 500m sight-in at the range later this week).
Regardless, I'm very pleased w/the performance of the .308 NDM-86/1P21 combo at all ranges.

Wow Tomac....you make want to work my butt off to buy one of these.

Both of course, but alas I have not the cash for such refined Coomie weapons as yours. I'll just have to see if a Saiga, VEPR, or even a Romak III will do me a little justice when I can buy one.

Aren't they about $1700 now? Now I have to go over and look at Dragunov.net .

Out of reach for me. Someday maybe.

UPDATE: I retested my 500m zero after removing then reattaching the 1P21 and as far as I can tell the zero hasn't shifted at all! The 18" 500m gong was easy and the repetitive and continuous hits (24 total) started to become monotonous!
So, I ran out to the BLM land where I fired another 36rds at my 1,200m target area (which when measured w/the 1P21 rangefinder turns out to be about 1m x .5m in size). This time, however, the wind was gusting continuously from my 7:30 up to appx 10mph. At 1,200m the wind has a lot of time to work on the bullet so while I did get a few hits by using the horizontal windage marks to compensate (not as many as I'd like) most of my shots were off to the right, at times as much as 8m! It was also interesting to note that when the wind was gusting the most the bullet would hit high by about .5m or so, evidently the wind was giving the bullet a little help along the way!

Wow, that's just impressive as hell Tomac. You've at least sold me on the scope.

I mounted my 1P21 3x9x42 on my Romanian PSL-54C. This scope is a tremendously intimidating piece of hardware to impress everyone even if it is on a PSL. They should have called it the Terminator Scope. I got mine from a friend who sold it to me for $50 bucks!!

The center L shaped bracket needed to be removed because my mount on the rifle is not correct for this scope.

I'm not certain which part you removed but if it's what I think it is you may find your scope unable to hold zero. Does the rail on your rifle have the semi-circular cutout for the locking lever's cam to fit into as it locks down?
Tomac

My scope rail on the Romanian PSL does not have the semi-circular cut. The bar was a certain thickness when installed and that prevented me from getting the scope mount tight enough to stay on the rifle. Removing that L shaped bar enabled me to get a tighter hold on the mount. The L shaped bar also wedged itself against my scope rail and pushed my scope over to the right of center.

After sighting in the scope, it adjusts well but will not hold zero if removed from the rifle then re-mounted later. You have to remove the 1P21 scope to field strip the PSL for cleaning.

The PSL does not have the correct Dragunov style mount needed for this scope.

The outer ring numbers show not only magnfication but range to target x100m when properly sighted in (ie: 4x = 400m, 6.5x = 650m, 9x = 900m , etc...) and the BDC adjusts for 7.62x54 bullet drop at that range.
Even though the scope's BDC is set for 7.62x54 it's still my fav scope and I still find it very usable w/my .308 NDM-86.

Here's a shot of the 1P21's reticle looking at the 36" gong at 750m:

I notice in your photo that your reticule is adjusted to the right of center, center being located under the rectangle. Have you thought of sanding down the mount rail of the scope to bring the point of impact more close to center. Thats what the Russians did in WWII with the PU and PE scopes. The grind marks on the mount is one way to tell an original from a built up fake using original parts.

If you mess it up, the mounts are easy to find.

Tomac,
A few questions for you;
1. where did you get those bipods in the pictures? I want one.
2. where do you get those 1P21 scopes?
3. I'd also like to know where you get those sythetic furniture sets as well. I hunt with mine, and I dont want to mark it up too much.
4. last, where do you get decent ammo to shoot in these? I have one in x54, and cant find decent ammo anywhere.

Thanks in advace,
Ian

G-D damnit! Why do they have to make it so difficult to figure out how to post an F-ing picture? It pisses me off to no end.

Tomac,
Thanks for the help. I contacted Tantal, and told him you sent me. The pic I was trying to post was one of my son holding my NDM-86. I have seen folks use a photobucket link, but I don't have a photobucket acct. cant we just cut and paste, or post directly? I dont know if I'll ever figure it out.

Thanks again for the great info!

Ian

How bout now? I doubt it, but we'll see

Where'd you go? Sand Hollow?
Pretty sweet rifles there.

Tomac,
Got some questions, as my IP21 will be delivered today. In a perfect world, with the scope/rifle zeroed at 300, and the reticle centered in the scope with the AZ and EL knobs on zero and zero. With those conditions, when you turn the knob to estimate range and change the relationship between sight and gun, does the reticle offset inside of the scope, or does the scope move independently of the gun/mount? When it does "change" is it both in AZ and EL, or is it just elevation that is changed?
When you and Creator started talking about Sand Hollow, I knew exactly where you guys were. I was stationed at Gowen Field for about 10 years, then Ontario for a few years.
You can really get some long range to shoot there. I used to shoot out at Vale.
Thanks in advance for any info you can give me.

Hi! Windage and elevation adjustments when sighting in will change the position of the reticle within the sight picture (ie: the reticle will appear to move up/down/left right inside the tube). But when using the main ranging knob on the right to range the target the entire scope body moves up/down (elevation only) with the reticle picture remaining unchanged within the tube. Be sure to sight in at the magnification that equals the range you're sighting in at (ie: 3x for 300m, 4.5x for 450m, 6x for 600m, etc). HTH, let me know if you have any other questions and keep us posted!...

Tomac,
Got it from Tantal today! Very impressed. This thing is awesome. My PSL is currently at CGA getting finished up. I am looking forward to shooting this thing. Pretty simple concept really. Once again, Doug is a great guy to do business with.
