Your terminology is confusing.
You went to resize another CASE, and the DECAPPING PIN broke, and a CASE is jammed in the die?
I don't know what you might have done to stick a case (although, usually is is lack of lube) but if you did, the only way to remove it is a stuck case puller. Costs about 15 bucks. If you're like me, after the first time, you'll never need it again.
