I just finished sizing and depriming some .38 brass. I am using a RCBS single stage press and die. A couple of weeks ago I had no issues. Today I had several occasions where the primer wouldn't push all the way out. I kept trying to screw the pin down a little at a time but still had issues. I don't remember how far out I have the pin now but it is a lot further than on my 9mm die. I kept checking to make sure I wasn't damaging the primer pocket. Both lock nuts were tight so I know nothing was loosening up. This was also the same brass I reloaded a couple of weeks ago. Any thoughts? Thanks.
