I picked up 1000 rounds of mil surplus .308 at a good price because it was slightly corroded. A little time in my Dillon Case Cleaner did wonders on most of it (I didn't have any polish cleaner to add to the grit but have some on order and will vibrate it some more). But here's my question - the head stamp on this ammo says "DAG93A0307". There's also a small stamped mark that looks like a "+" inside a circle. The bullets are silver colored. Does anybody know where this ammo was made and what type of bullet is used?
