Ok, so I was sizing a few cases after taking them out of the tumbler a couple days ago. The cases were well lubed going through a new Forster BR sizing die with the die backed out 3/4 of a turn as to size only the neck. Some cases went through the sizer smooth as silk and required very little pressure on the lever/arm/ whatever it's technically called. Some required considerably more work by me. Then this crap happens!!! What the hell? How does this happen? Even better question, how does one go about fixing this problem? Oh, should have mentioned, I didn't leave the case in there just to show off my new dies. It's in there so ---- tight I don't think it will ever come out!!!!
