PITA but it happens. I bought a pipe cap large enough to fit the OD of the die. Drilled a hole through it large enough for a 1/4x20 bolt to fit through. Drill the primer out of the stuck, tap the hole 1/4x20, you may need a few washers, screw the bolt into the case and tighten till the case comes out of the die. You will need a small pipe cutter to cut the case in half to remove your decapping rod. Of course the case is FUBAR but you save the die parts. Easy!! Of course during the process you have to use the correct language but you probably did that when you stuck the case.
