How about the firing pin??? From the print, it looks like the entire front slope of the firing pin would strike the inside of the breechblock. If that area is pushed in, it should leave a 'wear ring' on the firing pin. If it's worn or metal has been somehow removed, there shouldn't be any wear...I'm thinking...
The only thing similar to this that I've ever seen is chamber/bore erosion...
