9mm fmj berry bullets 115 grn
My Beretta pistol is a Bullseye Competition pistol built up by Gunsmith David Sams. It is an early version with a Bar-Sto barrel and the barrel is not removable from the slide. David Sams recommended a 115 grain FMj with 6.0 grs Power Pistol. He said, based on his testing, the best accuracy was with a velocity between 1150 fps and 1200 fps. I tested Titegroup, I think the Powerpistol was more accurate, but, I was shooting offhand. As usual, I test factory ammunition for velocity and try to keep under that velocity, assuming that less velocity means less pressure.
