Sapper771, when I said headstamp I was curious as to the year it was stamped. Again the stuff I have currently is 10. I've shot everything from 95 to 10, though I haven't shot anything in NATO older than 95 to my recollection. I don't know how long they've been stamping the year. Maybe as long as 9mm NATO has been around. Haven't seen any really old stuff though.
