ok, a little more info:
It is a 9mm casing. I did not take the photos or have access to it at this time. So the pics are limited to what I have on hand and so far it is just the headstamp pic.
I refered to a 7.62x39 cause we did recover one of those as well, to my knowledge it was the only casing recovered-----Obviously the scene is pretty old and finding these were the "needle in the haystack". I thought of Federal Cart. but isn't the F and C too far apart? This cartridge should have been shot about 7 years ago however I know that has little to do with the actual age of the cartridge.
PS: does anyone know if a high point / stallard 9mm pistol has a distinct firing pin strike? I would be intereted to know that as well.
