This is the exact combo I have been shooting winchester brass into one ragged hole.....I'm using 75.0 gr H1000 230 OTM Tatical and Fed215M.....be careful as this is a max load, I ruined some brass before backing down and would not suggest going past 75 or all your hard work and brass prep will be waisted as your primer pockets will be blown!
Well, I got out and shot today. I only shot a 73.0gr load max. My most promising results were 71, and 72 grs. Bot loads shot sub MOA. These were seated beyond mag length. I also had 71gr loaded to mag length that shot sub MOA. My largest group was 1.5" (only one load shot that) All others were right at the 1" mark or smaller. Going to load up 71 to 72.2gr in .3 gr increments at mag length and see what i can do with that. Hopefully will get to shoot before I go back to work for two weeks.
