The smallest was .127" and the biggest was .428". The smallest group ripped the paper funny so it looks bigger than it actually is. The gun wants to shoot just about everything I feed it. Guns like that are fun to shoot when I'm on my game. I had 4 rounds of the load for the smallest group, 89grs of R-33 with 230 Berger, and shot one, made a scope adjustment (the wrong direction I might add. It was early :lol: ) and shot the other 3 into .127". It was only doing 3000fps and is a really mild load so I'll try 90-93grs to see what I get can for velocity. It should shoot 3100+fps and if it's that accurate there I think I'm done with load development for this one. In the next couple weeks I'll stretch it out and see what it will do at 900+yds. I should finally have my dies next month too.
