Hey guys, I've put a ton of time on the range running IMR4064, Varget and H4895 through the rifle. First 200 rounds were 165gr Ballist tips and just finished running 180/178gr SST & AMAX through the rifle w/ H4895 exclusively due to groups from the 165gr bullets. I'm at 1.1 MOA with this rifle which has a 24" bull/fluted barrel and 1/10 twist. I have 8" groups at 570yds. I pushed up to 2725fps but it was punishing the rifle and I had primer flatten pressure issues. The 8" group was at 41grns of H4895 shooting 2575fps. I don't have groups that are more than 1.1MOA so that resolves shooter inconsistency. The SST for the most part are dead center but the Amax is usually .2Mil to the right. I haven't tried RL15 as of yet. The Varget and IMR4064 give me unperdictable groups that are far more than 1MOA.
The goal is to be 1/2 MOA at all distances. Any ideas on why the groups aren't better? Any help w/ would be greatly appreciated.
