if you can drill and tap a 1/4-20 or even 5/16-18 thru the primer pocket into the cavity of the case. then using washers that have holes greater than the .473 body of the case and not greater than the body of the die, you can assemble a dozen washers to the body of the die and over the case and then holding the die with a very secure wrench....(pipe wrench) one can thread a bolt into the tap and turn the case out of the die.

BTW both Hornady and RCBS remove stuck cases from their dies free.
