Couple problems happening here

Take a look at the extractor spring (the little coil spring below the extractor itself). When it is weak, the round will be pulled backwards, and rammed out by the next round. The dent is usually caused by the extracted case banging into the receiver. You should notice that the case barely clears the gun while shooting. With a fresh extractor spring, the case will jump over you.

I had a mismatched VoPo with the same 'features'. The cases kept hitting me in the face, or on top of my head, and all were dented. Finally I replaced the extractor spring and all went back to normal.
