I have run across some Portugese 200rd battlepaks, they are in brown vinyl battle paks and they are stamped --- 7.62 x 39 200rd
the actual ammo is brass cases with very sharp pointed fmj bullets, and the headstamp is
7.62 39 95 with greenish-blue sealant around the fmj and primers
It was crap to me, shot double the groups Wolf or Silver Bear would have. And It's not corrosive, shot it a month ago and no rush yet.
