Try putting it in the Freezer (0 to -20) the difference between the two metals should work. Of if you have a can of aair turn it upside down and spray the case till the die shows frost. you should be able to pull or tap it out. (all else fails get some dry Ice to freeze it)So I was setting up my reloading die last night and didn't pay attention to the fact that I'd put my hornady oal gauge case in my box with my fired cases. As you may have guessed I sized it and as it was not meant to be sized the rim broke off and now the case is stuck. I know this was very negligent but if anyone can give me an idea of how to get it out that would be greatly appreciated. From what ive read it uses 5/16-36 unef thread and I can't seem to find a bolt that matches that that thread.
