Recently got a Russian tokarev with CCCP grips and found this bit of ammo. I tried to identify the markings but my translator just says "steel". I assume these are from chinese spam cans but one box is in English. I am trying to find out if these are steel core or if its reffering to it being steel cased. The headstamp shows that it's from Chinese State Factory 11 at Mudanjang by Norinco 1984 manufacture which is surprising as I thought it would be alot older. Thanks for any help!
