I screwed up a load in 357 magnum. Only thing I can determine is that some idiot :banghead: used a jacketed load for lead. Loaded July 3, so maybe I was ready for fireworks.
Load was 7.7 gr. Green Dot, 158 gr. LSWC (MBC 357 Action), Federal SP match primers, 1.607 OAL, heavy roll crimp in resized mixed brass. DO NOT USE THIS LOAD. I had started at 6.5 gr. with moderate to heavy recoil. The 7.7 gr. load flattened, but did not pierce the primers. Gun is a Colt Trooper MK III, 6" that was new to me.
Can someone run this in Quickload and tell me what kind of pressure I had. Lee shows 34,000 PSI with 6.0 gr. Green Dot with this bullet. I am curios about the pressure, and certainly don't want to repeat and have to post in the dumbest reloading mistakes thread.
