Get a self tapping deck screw (1/4 inch thread) a washer the top does not go through, a short piece of 1/2 metal conduit pipe, allen or star bit and a drill for the tap (3/16).
When (not if) you get a case stuck in your die, drill the primer, screw the self tapping deck screw in through the washer and conduit so that you can pull the brass out.
or not, but this is what I do. Cheaper than messing up the die trying to beat it out.
