I have tried to push it out with grease it won't work. What happened is some one put a bullet, like a 275 grain short conical down the bore with no powder. Then somehow was able to load another charge on top of it later and was able to get the gun to go off! How this all happened is a mistery to me. So the original conical is REALLY ramed against the back of the plug. So th e guy try's a bullet puller and gets it stuck in there to. Then gives the barrel to me. I have no money in it so I have nothing to lose.
