Title says it all. Loads were with tight group 5.5 and 6 grains with acme 255gr coated Keith swc and extreme 255gr plated flat point. It’s not just me, others shot it as well. We were shooting at 25 yards. None of the 4 of us are great shots, but we can group much better with all our other pistols and revolvers. Any ideas. Better powders for 45 colt possibly?
