If you don't want to wait for UPS to bring you a stuck case remover, just make a trip to the hardware store.
You will need a
1/4x20 tap
#7 drill bit
1/4x20x 1-1/2" allen head screw
1/4 flat washer
Drill out the primer pocket and tap. Get a socket that fits over the base of the brass and rests on the bottom of the die. Thread your allen screw thru the socket and into the brass. Then you just keep tightening until the brass pops out.
This is the same set up as a stuck case remover, except they use a steel cup instead of a socket.
