So you are convinced the silver boxed Norinco stuff is corrosive? Anyone else? I haven't opened the crate yet but I will NOT be happy if I paid for NC to get corrosive ammo.
I just looked at my nail test board and the only one that didn't rust was that silver boxed Norinco ammo. Head stamped 71 over 90.All the other stuff is rusting, that's 2 kind's of copper washed case's (Norinco yellow and green boxed) and some East German ammo.
