I just purchased a used 20 gauge a few days ago. There is a slight grinding sound when I open the gun. It sounds like old grease or grit in the ejector springs or something. The gun wasn't used for the last 30 years or so. I'm not much of a gunsmith so I thought I'd ask here. I fired snap caps and everything works well. Does anyone have any experience with these. I tried cleaning it the best I can without taking the ejectors apart.
