I need some suggestions to resolve a pressure problem in my .357 mag. I'm trying to develop a medium load for my Rossi 461 snubby. I decided to try Ramshot Trueblue with a Hornady 140 gr. XTP. Currently, I'm using once-fired PMC cases and a Winchester small pistol magnum primer.
As always, I began with the starting load (9.3gr.) and planned to work up from there. The problem is, I'm getting bad pressure signs (flattened primer and enlarged primer pockets) with the starting loads.
The obvious solution is to reduce the powder charge, but that means going below the listed minimum. I am going to have problems with hangfires if I do that? Any suggestions would be appreciated.
