Norinco 7.62x39 ammo from the 80s. I can't remember but I thought that this ammo was mildly corrosive. Steel case copper washed loose. 500 rounds for $200.00. There may be more available. A friend of mine is getting older and is wanting to clean out some things. He keeps finding more stuff all the time. There may be some East German 7.62x39 later.
