WD-40 will not kill primers. Look around one of these boards, you can find a thread on a guy who tried WD-40 and a lot of other things that were "s'posed" to kill primers. They didn't.
Don't rely on WD-40 or anything else to kill a primer. Don't try to drive it out.
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.
Be happy, reload safely.
