I have tried kroil, heating it, pushing it down and letting snap back for about 2 days now. I am thinking about using a small drill bit and try spinning it. Does anybody have any other ideas? I had 2 blown primers when working up a load and it jammed the ejector. The ejector moves up and down but it will not come up any further than just barely above the bolt face.I am about to put the pin back in and forget about I am going to put a single shot floor plate in it anyway.
