I've been handloading for about 9 years now & casting boolits for about 8 years. Never an issue, til now. Shooting my New Vaquero 45 Colt a few days ago using 7.0 grains of Titegroup under the NOE 285-WFN. After 44 successful rounds, number 45 had considerable more blast, so I stopped to check things. I could not eject the brass. The gun looked fine. I don't recall any excessive recoil, just a louder report. According to Brian Pearce, 7.5 grains of the same powder is maximum at 14,000 psi under the RCBS 270-SAA boolit, which actually weighs 285 grains also with wheel weight alloy. With all that said, I was wondering if someone with the Quickload software could give me an estimation of what the pressure might be for a double charge of my 7 grain load? Thanks
