Default Accuracy results ZQI, Malay, AE, WCC



Went to the range this morning to sight in my ďprecisionĒ rig, and I use that term lightly.



CZ 550 FS chambered in 308, mounted a PA 4-14 ACSS scope on it last night in CZ 550 rings (the 550 does not use a standard 1913 or weaver rail, it is a 19mm dove tail with a recoil lug on the rear ring)

It was 35F this morning and warmed up to about 50F? By the time I was done shooting. This is the first time Iíve actually sat down and shot for groups for the sake of shooting for groups so Iíd expect that same ammo and conditions someone else would shrink these considerably.


After this I can say that I like the CZ rings but the screws they use are extremely soft and fragile, I will probably have to remount the scope using new screws, they are M3.5x8 for anyone that may need that info

The PA scope seemed to have issues with tracking when we zeroed do to the cold but after adjustment we let go scope sit for a minute or 2 and seemed to track fine.



This is the first group with Winchester, I think these were 150 grain hollow points for hunting, the box was torn up a while back and threw it away but I remember it was a black box with a deer sillouhette on it and Iím lretty sure it said 150 grain on the box. I wish I had more than the 1 box I used to get on paper because the rifle seemed to really like this ammo. The 3 shot group was my last shots fired using the star as POA. Those were also the last three I shot after adjusting the scope with that ammo.

Grouping was about 3/4Ē center to center.




This was American Eagle 168 grain OTM, this ammo was loaded as match ammo for M14/garand actions and I have some left over from my M1 A scout waiting to be used. I only had 10 rounds of it to sight POI to POA unfortunately since Iím using the rest in a class in a couple weeks and have just enough left over to make it through. With (2) 3 shot groups first using the star as POA then using the circle of the R as the next POA after adjusting a little. Both were about 1Ē and wanted a couple groups from the 10 rounds to see what I could expect from the gun with my skill level. This ammo is also about 6 years old but I donít think that should be a factor in accuracy however it is the reason I dont want to buy more for the class as POI will likely be different after 6 years between manufacturing



This is some of the Malaysian surplus that came in earlier this year. Lot 1 of 1-86, I assume this means the first lot manufactured in January of 1986. There is a really nice group in there of 5 rounds that hovers at the 1Ē mark. I think itís impor that I shot these 5 shots in succession but overall this is a 10 shot group since I had plenty on hand. The overall 10 shot had longest center to center of 3.625Ē



This is some ZQI I stockpiled from Walmart. Still have a ton of the stuff. I had some pretty severe horizontal stringing and Iím not sure whether itís just how it grouped or do to being tired of shooting groups or some other change I didnít take into consideration. Itís a 10 shot groups with longest center to center being 4.875Ē.

Just interesting results I had and figured Iíd share them since Malaysian surplus has been a hot topic lately and ZQI used to be once upon a time.

I get better groups with all that ammo using a FAL and iron sights.. you’re using a bolt action which should be able to smoke the FAL.. your form is off.

I din’t get your methodology either. It seems you’re adjusting the scope while doing this and then cherry picking 3shot groups and ignoring flyers, then shoot a string of 10 with another sample.. where’s the baseline and consistency?

I agree that ZQI is the worst out of all of those though.

Iíve never shot guns with optics for most if not all my life, this is the first seriously scoped rifle Iíve had and shot for groups so Iíve a lot of learning to do you are right.

Group sizes were just based off of ammo availability, and how I was shooting. I had a lot of ZQI and Malaysian because it was cheap so I shot a 10 round group of each for giggles n shits. I had 20 rounds of Winchester which I used to get on paper and get a sort of zero first and once I started getting where I wanted and getting used to the scope I only really had that one viable group as everything else looked like a shotgun pattern. I only had 10 rounds of the AE and managed to get a couple groups but it was shooting much lower than the Winchester so I did a shot then some adjustment until I was close to POA POI being same

The reason some of these look ďcherry pickedĒ is because those are a string I shot while zeroing using the same POA before I adjusted the turrets again, I basically did 3 shot groups then adjust. There is really nothing scientific about these groups.
