I was gifted 100 pre primed .357 mag brass today by a friend. His dad used to reload and had these laying around. The problem is, I don't know what type the primers are. They could be mag primers or they could be standard ones. I use blue dot for my .357 loads. Would it bother anything if they were mag primers? If it is the better idea to remove them what is the preferred method? Touching them off doesn't sit well unless you want to jam a cylinder up (don't ask how I know). Decapping live primers sounds like a little to much excitement. So what say you?
