I found a couple odd boxes of 7.62x51 NATO surplus ammo and thought I'd see how different they might be in one rifle, my SIG 716.
I had the following:
South African WA 80 R1M1
Portuguese BF 80-30
And some newer that I've been shooting a lot of lately:
West German DAG 93 0340
All have the NATO + in a circle symbol.
I don't really remember, but I believe my SIG 716 was given a solid 50 yard zero with either the DAG or FNM surplus ammo a few months ago.
So I started with the South African WA and verified the zero was reasonable drilling a 3" steel plate at 50 yards with a center hold, followed by nailing a 3" plate at 100 yards with a 6-o'clock hold. Then I moved to 200 yards and was nailing 10" 8" 6" & 4" plates with a half mil come up on the mil dot reticle. On to 300 yards where a 1.5 mil come up was drilling 12" 10" 6" & 4" plates. Finally on the 400 yards and a 2.5 mil come up was nailing the 12" plate. Had no luck with the 8" plate as the wind was just too variable for me to be that good with ammo that is generally regarded as 2moa at best. The impacts on the 12" plate suggested I'd need some luck on the 8" plate
.
Extremely pleased I moved to the Portuguese BF 80-30. Repeated the shooting and used the same come ups with the same results, hitting the 12" plate at 400 yards every time and missing the 8" plate every time, the wind hadn't gotten any better
Finally I tried the DAG as my "control". This was what I found surprising and wonder if a better BC bullet in the DAG could account for it. Same results at 50, 100, & 200 yards with the dead on, 6 o'clock, and 0.5 mil come up. What was different was that at 300 yards my come up was only 1 mil and at 400 it was 2 mil instead of 2.5 mil. Same poor results on the 8" plate at 400 yards
I found it interesting that two very different 7.62 NATO mil surplus ammo brands shot virtually identical out to 400 yards and a third newer production was essentially identical out to 200 yards and had half mil less drop out to 400 yards.
I never touched the turrets. Maybe not a surprise to y'all, but I expected I'd need to tweak the holds for all three loads at 200 yards and up.
