A fellow brought me a winchester model 12 20 ga. that he fired one of those aluminum base shells in. It jammed tight and won't extract. I have the trigger group out and holding firing pin in can't pound the shell out. I tried to pop the extractor over the lip of the case but can't get it back far enough to clear the lip. Any suggestions????
