Did i miss something? Why not use the RCBS stuck case remover kit. They even have one for bushing type dies. Costs $24.00, 10.00 for the bushing dies, plus shipping direct from RCBS. Probably less the replacing the sizing die. Works great. Expanding ball would be impossible to remove. I've stuck two cases. First one was so long ago, I don't remember much about it, but i bought the kit and it worked. The second was with a die that was shortened slightly to correct a head space problem. (Didn't work), but the kit also easily removed it. I'd reccommend that every reloader buy one "just in case". Cheap insurance and after a few minutes work and your back in business.
