Today I was sizing some .38 Spl brass and something strange happened. The brass was once fired Federal factory stuff that I recently bought. This is the first time its been reloaded, so the primers had to be what the Federal factory uses.
Any way, the decapping pin hit the primers to push them out and on about 30 out of 250 cases the top broke off the primer leaving a small ring of what was the cup in the primer pocket. I was able to insert a punch in the pocket and twist what was left of the cup out without too much trouble, but still, I've been reloading for over twenty years and I've never had this happen before.
Any body else ever had this happen? Is it a problem with Federal primers? Any ideas as to what happened?
