What do u all think of using H BLC2 for 55 gr or heavier gr loads for a ar15. I have varget, 322,335 alient #15 and a few others. Might have to get some h 4198 also to try. I have Hornady 55 gr fmj’s Sierra and horsndy’s 68 and 69 gr and some Sierra 75 gr and think I got some Hornady 77 gr that is supposed to load in factory mags.got two ar’s one in 1/9 twist and the other in 1/7 twist. Only got up to 300 yards at my range to shoot so what do you all think of BLC2 in the ar?
