Is it a chip or a dent? That is, is there metal missing out of the primer or is it just dented.

Is the mark always in the same orientation? That is, if you chamber the cartridge with the dash in the "30-06" always at the 12:00 o'clock position, is the mark always in the same orientation?

Is there anything on your boltface that could make such a mark? Particularly anything with that orientation to and distance from the firing pin?

What steps have you taken to discover if the mark is made before ejection from your action? What action are you shooting, by the way? Bolt action, falling block, sem-auto, etc?
