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...?
Those are the experimental fire pin ID marks made for identifying the gun that shot the bullet. ^^ I was just pulling your leg VT.
Aha. Some of the marks are, ah, disruptive to the metal of the primer. I wonder if they got any blowbacks during their experiments.
To me, and this is just to me the difference seems to be in stryker fired pistols. I noticed those strike marks when I shot a Glock vs my SR1911 Rugers. I picked up some .45 cal brass this week end and it had similar marks but the guy next to me was shooting a stryker fired pistol. I could be wrong tho. Tommy
I had a question on another forum about some 40 s&w's. I was told they were fired by a Glock. This info was given based on the firing pin indent that looked exactly like those. I'd say they were fired from a Glock. Just an uneducated guess.
I agree. Those look like a clock firing pin mark. Have a few glocks. That's what the firing pin primer mark looks like.
