Call Dillon at:
800-762-3845 and they will send you a NEW primer tube FREE. They do this for a reason, A stuck primer can happen, and for several reasons, the main one being an out of spec primer, and nothing to do with your Dillon primer feed.
RTM. I'm glad you got the thing out without hurting yourself. Dillon gives instructions for this very thing. They instruct you to dispose of the tube and call them for another that they will send for free like was said before. Go ahead and get a couple of extra large and small pickup tubes and you won't even have to slow down (much) if this ever happens again.
