Check your extractor. If a claw is broken, it will bias the empty round to one side where it encounters corners and edges inside the action. I've had empties that displayed burrs on the lee sides of karate chops to the brass--from which the next step would be to knock those burrs off to create shavings inside the action.

My stainless Luger chopped a burr on, or at least dented the case mouth of all empties. By indexing with a Sharpie, I found it was happening on the left side. The extractor Claw's left side was longer, and would yank the empty out in that direction, and slam it against the inside wall of the open action. Yup, sure enough, there's a 90 degree corner in there--nice and sharp.

Dressing the claw with a diamond needle file evened things out enough to minimize the problem. I didn't want to go too far because stainless extractors are made of "unobtainium." The empties all still have a shiny spot, and maybe a small deformation,--but not enough, I think, that reloading won't fix it.
