My photo-taking skills may make this query unanswerable, but... if you can make them out, what do these examples indicate? I bought a couple thousand pieces of once-fired police range brass a year or so ago. A majority of the caseheads I have looked at have firing pin hits like these. While I'm at it - most of the cases are head stamped 'Speer'. many of them have a small number 13 at the 9 o'clock position...?
