Well, not the whole case, just the neck. Have been doing pistol reloading for a while, but the rifle version is new to me. Must have forgotten to lube the inside of the neck on one piece of brass, cuz the neck is now firmly stuck up inside my Lee .308 sizer die. Followed instructions with wrench and hammer to remove the obstruction, but no luck. Any ideas other than mailing the die back to Lee or Andrew Higginson for expert removal?
