I've been handloading for about 32 years, and last night I had a first. I've used a Lee Auto Prime for most of those years with excellent results. Got one of their new ones with the square tray and used it last night for the first time. After almost 200 rounds (did have some difficulties that I didn't have with the old style), something didn't feel right, so I stopped, took apart the tool, and the case wouldn't slide out of the shellholder. The primer had gone in sideways, but not all the way in, preventing it from coming out.
I have a decapper for crimped primers, but wasn't about to start tapping on a live primer. To kill the primer, I sprayed some spray lube on it, but haven't tapped it out yet. Just wondering if that has happened to anyone else, and what you did to kill the primer? Water? WD40?
