You can probably tell from my last thread in this section I was getting some ammo. Got a bunch, most of which I know what it is. These 5 I kind of know what it is, but want to confirm, partly if it is corrosive or not.
M67 NNY over...oldest stamp is 1985, newest is 1992. Corrosive or non-corrosive?
M67 IK over...looks like 86 to me. Is this Igman? Corrosive or non-corrosive?
IMI over 7.62x39 thinking this is newer commercial Israeli ammo? Maybe Boxer primed? Primer looks a little different to me.
Thinking these last 2 are Chinese, but I have never seen the colors of these casings before. They look more like a Poly finish than a lacquered one;
Matte Green 61 over 81, Corrosive or non-corrosive? Lead or Steel core?
Matte Plum 71 over 89, Corrosive or non-corrosive? Lead or Steel core?
