You can back that down slightly, 5.8 gr gives factory +P duplication, plus a few foot seconds for me. Loading to Max isn't generally a good practice.

YOU TRANSPOSED NUMBERS THERE DUDE!!!!!!!!!!!!! THAT'S 5.8 GRAINS!!!!!!!!!!!!!!!!!!!!!!!!!!!
OK, load data with Berrys can vary from mid lead bullet level to same as jacketed (slight velocity differences) largely depending upon caliber. Generally, I find with Unique, I can back down about 1/2 a grain from my jacketed loads and get the same velocities. Power Pistol seems to generate an extra 50 foot seconds.
If the dies available aren't taper crimp, seat the bullet so the roll crimp is over the leading edge of the full bore body and back the loads down at least 1/2 grain.
