my 2 cents, having a box of wolf 7.62x39 in front of me it says made in russia, steel case, fmj, says non corrosive on front of box and non-corrosive berdan primers on side of box.
also having a box of american eagle, made in usa, 7.62x39, brass case, fmj, non corrosive primers on back of box.
Im sure that 10 Bears have fired many more of these than i have, im sure that he is right, and most russian is corrosive and most american is non-corrosive and my info just muddied the waters, but in my looking at the boxes in which one states both non-corrosive primers and non-corrosive and the other just states non-corrosive primers so now my question is the bullet suppose to be non-corrosive or is the primer suppose to be non-corrosive?

Corrosive applies to powder and primer.

Inexpensive powders and primers are made from chemicals whose
reactive process leaves behind an acidic material that reacts with
ferrous material (steel and iron). Thus creating corrosion, unless
that acidic quality is neutralized or removed.

Bullets (projectiles) are not considered corrosive Unless you are processing Incendiary, tracer or steel jacketed ammo.

The reason I include "steel jacketed" is because it will wear riflings
faster than copper or brass jackets. Therefor it has a type of
corrisiveness all it's own. That is my two cents worth. Wink

I think most of the corrosive ammo is old not many Country's using it much anymore...... All the Wolf I've seen has been non-corrosive..... And all my Norinco is also non-corrosive... Wolf used corrosive primer years ago I beleive... But not any more....I've heard something about South African being sealed with tar and causing some fouling trouble on FAL's.....

Yep,the Russian ammo will corrde a gun fast.Fire a few dozen rounds and dont clean your rifle and you will discover just how fast.If you can afford better(Americian ammo) buy it.Or you could try not firing your rifle and let it sit in the case.No fun there.

50/50 mixture of ammonia and water will take that superheated salt out of your gun right quick. Just a quick swab at the range after you're done shooting, then a full cleaning job at home.

I'm referring to the statement that Russian ammo is corrosive.. it's not not anymore it's also cheap and fairly accurate

The surplus ammo is, not the modern-day stuff. I'd rather pay $7 for 20 rounds of Wolf 7.62x54R than $18 for 20 rounds of Winchester 7.62x54R.

But I can reload the Winchester brass as well.
