The slide lock is not the issue. The ejector is engaged with the rim of the case, it is not in full battery, it is not in the rear location. It is stuck midway. The extractor will not let loose.
I am full length sizing, but when I seat and crimp, I do not perform any final "sizing" operation. I guess I need to use a final sizing die after loading is complete? When I drop a case into the chamber of the barrel removed from the gun, a factory round clearly seates on the rim of the case like its supposed to, my reloads seem to stop short of the rim.
