Thread: Building a service rifle load

*use at your own risk

in my 16" 1:7 open class

25.9grn of ar2206h with a 55gr hornady fmj, (seated mid canalure) i got 1" groups (bench rest)
24.2grn of ar2206h with a 62gr ADI fmj, 57.05mm OAL i got 1.5-2" groups (bench rest)

i got very similar results with my 20" 1:9 Service rifle using the same ammo, (the 62gr improved a little)

I've moved onto Benchmark 2 and xtreme 55gr fmj (copper plated) projectiles, find they perform on par with the hornadys and much cheaper.

Cheers Glycerine

Was this with 5.56 or .223 brass?
