Tried to search but do not find much. Does anyone have a complete list or a link to a complete list of commercial head stamp markings? ie: R-P, Peters etc. I have a few K of brass and trying to sort it all.
That ammo could have been made in Syria, Argentina, or Mexico.This is a curious 9mm case which caught my eye at my local range the other day. I have never seen one like it and wonder what it is. The headstamp reads FM. 9mm Luger and the case appears to be copper or perhaps copper washed. Here is a photo of it with a brass case for contrast.
