Is there any way to tell if a round is corrosive or not ??? I may be buying some from a buddies friend and he says it is non-corrosive, but can I actully tell, or just have to take his word on it. Also, what is 7.62x39 non-corrosive going for these days $$$???

"...any way to tell..." Not by just looking at it. Unless you know where and when it was made. This is one time when making assumptions is safe. If you don't know for sure, treat it as if it is and clean accordingly.
 
I just do not want to get ripped off and pay a higher price for non-corrosive only to find out it is not. I also bought some ammo of a fellow gunnut a while ago that was South African PMP surplus, with brass shells, but cannot remember if he said if it was corrosive or not.

SA is not corrosive. What ammo is it you are buying?

I will find out tonight what kind of ammo it is. If I was smart I guess I would have started this thread already having this info. :redface: Is it possible to safely pull the bullet, empty the powder and shoot it somehow at a metal plate and see if it corrodes???
 
"...empty the powder..." It's not the powder that is corrosive. It's the priming compound. Corrosive primers have salts in the compound that gets into the micro grooves in the steel and causes rusting. Even if it is corrosive, it's not the end of the world. You just flush the barrel with hot water then clean as per normal.

i dont know if this helps. i got two different types of 7.62x39 spent casings.

i looked in the corrosive casing and i noticed 2 tiny holes at the bottom where the blast enters, while in the non-corrosive american made casing there is one slightly larger hole.

since i only shot one type of corrosive ammo , i dont know if this is common for corrosive ammo to have 2 holes in the botom of the casing.:confused:
