Thread: Hornady 62 gr 223 proj not grouping

I shoot 62gn in my Ruger Ranch II, 1:8 twist, 16 in barrel, suppressed. Best groups I've found are up around max load or just under, around 2650 to 2750fps. Powders I've trialed are, 2208 (excellent at 0.5 gn under max so light compression), Ar22065, BM2 (also good group.) The Hornady 62gn SP has been my goto and started with them in Belmont ammo with excellent results. Might just suit my rifle. It also likes 69gn Sierra MK.
