I am wanting to build an open glock and i have seen the kits from jager and i have seen sjc videos. I am currently shooting a glock 34 with rainier 147gr FP with WSF at 4.9gr at 1.162 OAL with good accuracy out of a Lone Wolf Barrel. My question is does anyone have any load data for 147gr bullets and can the rainiers be used in a comp gun? I am looking at keeping the fps at around 1125-1130 for the minimum pf. Any help with powder, primer, case, and bullet choices would be appreciated. thanks in advance
