[canadianmarksmen]

All surplus 7.62x39 is corrosive. Clean well. Research and find a method that works for you.

If it's Czech surplus, then it's more than likely corrosive. Not a big deal if you clean it right away (gas system included)

In the past, I have pulled a bullet, dumped the powder and struck the primer to blast the bottom of an overturned steel coffee can. Left it in the basement for a week, and sure enough, you could see significant rusting where the residue was.

I find that surplus ammo leaves a distinct odour and taste in the air.

That is the smell and taste of dollar savings Sir

Sorry, that's supposed to be corrosive.

There is lots of Chinese surplus out there that is non corrosive. The Czech stuff is corrosive though. You did good by cleaning well.

When in doubt, assume any Combloc surplus ammo (e.g. 7.62x39, 7.62x54R, etc.) is corrosive, though there are a few exceptions.

havent seen recently any milsurp ammo that was non corrosive, just think it is unless your spending $15-20 for 20 rounds.

I read somewhere that any surplus ammo manufactured after 1982 is non corrosive. Could be wrong

Boiling water and a transmission funnel are my 858's best friend! Hoppes Elite Bore Gel is supposed to work well for corrosive ammo(as it is water based) but I always also use boiling water for peace of mind.

Yep, you are.

I was under the impression that the chinese stuff lever is selling dated after 1970 was non corrosive and he is selling it as such as well??!! any insight to this and how would one find out if in fact it was or wasn't?

 

[altaberg]

I have non-corrosive, brass cased surplus.
(Saudi Arabia Ministry of Security on the crates or such).

Wasn't too expensive either thanks to CanAm.

How can you tell the difference?
Shooting corrosive you can smell the Chlorine.

I'm sure it wasn't corrosive if it was marketed that way. Some Chinese ammo after 1970 is indeed non-corrosive, but not all of it. I've fired 1975 headstamped stuff what wasn't corrosive and some 1971 stuff that was.

When in doubt, assume it is unless you like rust. Usually you can smell it if it's corrosive, but not always. I've had some very mildly corrosive Ukrainian stuff that you couldn't tell from the smell.

Silver box Norinco is non-corrosive. It's for US civilian market and it's very cheap.

I love the smell of Czech surplus in the afternoon.

I have some Lapua Super Club .22LR that smells just nasty tho.
