Could someone help me identify this ammo? Just picked it up this morning on the way to the range.
It comes 30rnds. to a cardboad box (looks like a mini Chinese food take-out box) packed vertically, bullet end down.
Headstamp (not listed in my on-line reference) has 86 at the 12 o'clock position and 13 at the 6 o'clock position.
Box is marked "30 RD 5,56x45mm BALL M1A3". Stamped on the side is 378 A/86.
Shot thirty rounds, seemed to do just fine, I've got 60 rounds left. Paid $3.50 per box.
Can't find any reference to it, what do y'all think?
