Re: Opinions needed- 230gr Berger H1000 Ladder Test
As for the shots 13&14, those were the best I saw too and the three shot group was with them @ 102.8 gr. on the right, it's not bad at just over 1 MOA and I would have been happy 20 years ago but I'm wanting better nowadays.
Now I see what you did. I did'nt connect the ladder test with the 3 shot group below until you explained it.
If you already tried playing with seating depth and primers I would call it quites with the 230s.
10.5 twist seems odd though, are you sure the rod was turning all the way through? (no matter, 9" would be better anyway).
