Yep, stuck cases suck.
I got my new Forster press and they advertise that it's powerful enough to size a case without lube. Thought I'd give it a try with a .30-06. Don't know what I was thinking.
It could probably pull the sucker out, but the rim gave way first.
Go to ace hardware and get an allen head machine screw, drill bit, tap, and washers and with the right size socket as a spacer you can pop them right back out again without waiting for a stuck case kit to ship.
Find one a little bigger than the primer pocket and a fine pitch so you get optimal leverage.
