Since the gun is chrome-plated, is there any chance spring-loaded electrodes made contact there and the apparent "punch mark" is just an absence of metal plating on those spots? The way to check if they are actual punch marks is to paint the surface with Magic Marker and rub a known flat piece of steel over it. If they are punch marks, the marking die will rub off in circles around them due to that being raised when the punch upset the metal. Gently applying a diamond hone just to remove such raised areas would be safe to do. Otherwise, the marks themselves should be harmless. 45 Auto pressures are not normally adequate to mark a case head much.

Wouldn't it be simple to post a picture of the breech face?
Most electroplating is done strung on wires, BTW.
