I was shooting the other day with my 12 ga Yildiz O/U. Hadn't shot a ton, but enough to heat it up pretty good. I went to eject two spend shells, and the top extractor got stuck. The shell was stuck in there tight, so I couldn't pull it out. I shot my 20 ga instead, so no big deal, but I was a little miffed. After the gun cooled down, the ejector worked just fine. I used grease for lubrication, and there was quite a bit of it. Did I just over grease it, and it got gunked up, or do you think this is a bigger issue? Thanks.
