I would clean the action and oil it. Search for worn rounded edges at the shell stop and extractor. Shoot it and see what happens. If it is pushing the bullets out of the shell with the extractor, it is still strong. I am not familiar with that model, what does the stamp say it is chambered for? Can you post a picture of the mangled bullet?
I would think it should extract loaded rounds without damage, unless it is chambered for shorts.
You can't fix stupid....however ignorance can be cured through education!
