I am chasing a problem with a build that I had done for me. It will consistently fire factory, but not my handloads. Looking at my primer seating I don't see any difference in my primer depth. The primers get light strikes. It was suggested that I reseat my primers because the firing pin might be trying to seat the primer. I'm fairly certain that isn't the issue, but after work I'm going to try that on a few of the cartridges after pulling them apart. The shells seem to be seating fully, but that did give me the thought that even though it seems to be chambering correctly maybe it isn't. Some of the light primer strikes were hard to eject. So I thought to reset the shoulder on a few of the shells and try again.
Does a free floating firing pin have difficulty setting off a raised primer? My primers aren't raised, but maybe the same principal if not chambering fully? I'm grasping at straws. Not many gunsmiths in my area. The factory stuff on hand is PMC Bronze, it goes bang all the time. Looking at my primed cases and the factory stuff I don't see a difference in the primer depth.
I'm not very good at diagnosing this stuff so any suggestions would be most welcome.
