Agree with Robin. Seems like it’s really pointing at the ejector as the problem. If the case comes back with the bolt, that would say the extractor is doing it’s thing. But if the ejector or spring is weak/damaged, that is exactly the outcome....case just lays dead at the back of the action. We all assumed you already looked the ejector over well. If it’s not that, unfortunately you are at “take it to a gunsmith” time. Once again, something which many of us could fix with a little look-see. But diagnosing a problem via “Interweb” talk becomes very difficult after exhausting the Usual Suspects.
