While I am nearly positive that all the 7.62NATO is non-corrosive, I'm not which of the others are corrosive. I have no problems shooting corrosive ammo, I just want to know which cleaning technique to use with the different ammo.
I think its safe to say that all American Milsurp ammo is non-corrosive and all Foreign made Milsurp is corrosive.
That's my opinion. I would treat all foreign ammo as corrosive even though I think all foreign 30-06 and 7.62x51 are non-corrosive.
