    :question:Is there any way to tell what ammo is corrosive and what is not?
    Mods, sorry if this is in the wrong forum, I couldn't see another one that would suit perfectly.
    Thanks guys.

    762x39 in particular i'm not sure of the manufacturer it's the stuff that comes in packs of 40 on stripper clips.
    it's this stuff and I just found my answer.

    No, not all berdan primers are corrosive. A somewhat simple test if you aren't sure is to pull the bullet and dump the powder from a suspect round, place the muzzle about 6" from a clean (bare metal) steel plate and fire the primer. Clean the gun well and leave the plate outside for a day or two. If there's a rusted round blast-pattern on the plate after a day or two, it's corrosive. You can also tell by putting a drop of water in a fired case and see if it turns green after a few days, although if left long enough, water in a brass case will almost always turn green.
