[QUOTE="green 788, post: 645876, member: 3781"] ok... my bad, I didn't see that when I read your post the first time. It's gotta be those solid copper bullets then, harder engraving force = higher pressures, but if it's shooting well, all is well... I use the 300 grain Sierra Matchkings, and 89.3 grains is giving me just at 2700 fps... 92 grains gave me 2800 fps, but pretty flat primers and some ejector swipe... so I dropped it down to the next accuracy node, which I found at 89.3 to 89.5 grains in Lapua brass.
