Norinco 7.62x39 Non-Corrosive?

[Hokus Grey]

Is this the head stamp for the non-corrosive batch?

Cool, thanks!

Is there a thread on identifying corrosive ammo?

I believe anything made before 1994 used corrosive primers. Someone correct me if I'm wrong.

I don't know if 1994 is a hard number, but it is generally mid 90's they started with non corrosive.

Anything in the 1970-73 chinese surplus is better described as "sometimes corrosive", they seemed to be mixed in each can, so other than testing every single round, you're best off treating it as corrosive.

Can you tell just by looking at the stamp on the bottom of the case?

 

[Hokus Grey]

Ok, so now I'm curious; what do the head stamp numbers mean?

Chinese used it into the 80s, even some today for the x54 we imported made in 2011

So 63 ontop and 93 on bottom is factory 63 in 1993? My stuff is most likely non corrosive then ? ( it's 7.62 x51 )

Canam do you have a document that can explain this more? Or a link?

I have never seen corrosive chinese x51, although they did make it in the early days, I'm told

no, sorry. Best bet is to visit the IAA site

Copy that CanAm. Could you send the link to me either here or via PM.

One last question, is Sellier and Bellot 7.62x39 ammo corrosive?

If it's steel-cased surplus, it's corrosive.

Stevo, how do you check for steel case ammo? (sorry I am totally showing my lack of experience with this ammo)

you can just tell by looking that it is not brass, but brass surplus yugo will also be corrosive, but rare in Canada

A magnet works too. The Czech S&B surplus will have "BXN" and a two digit year on the headstamp. Generally a grey-green finish though some is grey.
