I am new to the forum. Long term lurker, first time poster. I recently purchased a Scar 17s in FDE. Along with the Scar, i got a steal (i think) of some Austrian Hirtenberger 7.62 x 51 ammo. I bought 600 rounds, in 200 round battlepacks for 50 cents a round. I do not know much about this ammo other than it's Austrian, the label says Hirtenberger 147gr 7.62. The primers appear to be berdan primed. I am not sure of the headstamp or what year it was manufactured. I have read some of them are magnetic, but this specific lot is not. If this is in the wrong category, please move. Thanks in advance.
