The only stuck case removers I've ever seen were intended to clear gun chambers... I've got those in several calibers but have never needed to use one... at least not one I had. I spent years getting the stuck case of an old round-nosed steel jacketed 7.92mm round WITH THE BULLET STILL IN THE NECK OF THE CARTRIDGE out of a Gewehr 88 Commission Rifle once upon a time. The solution came when a neighbor down the street threw out some kind of shoe rack intended to hang from a closet door. It was made from about 30 cal. mild steel rods... i.e. just a little smaller than bore diameter. I cut a piece a few inches longer than the barrel of the Gewehr, slightly beveled the end that would contact the bullet, and drove bullet and case fragment out as pretty as you please.with a 4 Lb. sledge.
