Once upon a time, the loading manuals recommended small rifle primers for the .357 Magnum cartridge. This practice has fallen by the wayside over the years. I've always used small pistol primers in the .357 Mag and .38 Special with good results and no ignition problems except with some of the slow burn ball powders (WC820, AA9 and H110) in the .357.
I suddenly find myself blessed with an abundance of WSR primers.
What does the brotherhood say to using them in the .357/.38 Special? Any experiences good or bad. Any pressure signs observed. Any body tested them one against one with the same load of regular powders (Bullseye, Unique, Herco)./beagle
