DWM Commerical breechblock question

As noted above, this is a most interesting condition. On examining the fired primers, it is obvious that there is a depression of the breechblock face in the area of the firing pin hole. It seems to be very uniform. It is as though someone used a tapered punch/drift and struck the area surrounding the firing pin hole., basically over correcting the problem.

I had a protrusion of material surrounding the firing pin, supposedly from dry firing, and corrected it with a flat faced brass drift and a hammer.......now the breechface is uniform. My spent primers look normal.

If you are overly concerned about it, and wish to continue shooting it, one could fit an aftermarket breechblock just for firing.
