I was out with my shooting buddy and shot 60 rounds of SA PMP surplus ammo this past week. Used 2 rifles,
(1) My 18.5 inch carbine, AKM -clone sage stock, scoped
(2) Buddies,22 inch, tuned (Hungry style) with iron sights, still in Norinco stock
Carbine shot well under 2 inches at 100 yards, and my two groups at 200 yards were under 4 inches. I was able to hit a 12 inch steel, and 8 inch steel 100% out of 10 shots at 200 yards, the 4 inch steel had a 50% hit rate. At 300 yards I had a 100% hit rate on an 18 inch steel plate.
At 100 yards my match handloads (lapua 167gn, norma brass) shot groups around 1 inch ~ 50% better than the MilSurp.
22 inch rifle shot 3-4 inch groups at 100 yards, we did not try to change the norinco sight after I got it zeroed at 100 yards
All of this was done with bags, off a concrete rest.
So when I got home I decided to see how consistent the ammo was, I opened 5 boxes and selected 5 rounds from each, I measured the runout (RO) and COL (measured to the ogive with a comparator), the results are below. I do not have much experience with MilSurp ammo, but this stuff seems consistent, both on the range and on the measuring bench. It is a far cry from my match handloads, but I am still very happy with it.
Shooting conditions were less than ideal!
