I have 2 320 round boxes of the hard to find german metal works 7.62x51 this was from a shipment that came in and sold out really quick. it is surplus ammo and I bought it a couple months ago.
price is 220.00 per 320 round box.
buy both! for 420.00

I do not know anything else about this ammo other than it's brass cased and from Germany.
the box is all german writing.
