7.62 x 39 question

[icecold]

Hi, a guy was cleaning out his crawl space at work and came across this tin. He has no use for it so I happily accepted it.
So it was a sealed tin and the winding key wouldn’t work so I had to rip it open.
750 rounds in 25 rounds per paper package ( I assembled the stripper clips with my surplus clips )
Can anyone tell me any details on this ammo. Specifically wondering if it is corrosive or not.
Thanks for any insight.

It's a safe assumption that any ammo coming from a tin can wrapped in paper is gonna be corrosive. Odd that the words "ball" and "rounds" is stamped in English. I guess it could have been done by an importer.

You can test it to see if it is corrosive. Google “corrosive Ammo nail test”. There are videos on YouTube showing how it’s done.

It’s likely Chinese corrosive. Does it have a 61 or 71 on the headstamp? Looks like 1981 production so it may also have that on the headstamp.

what head stamp on the cartridge. During the 70's there was some production of 7.62 x 39 cartridges in American factories for training purposes and supply to 'friendly forces" for use in captured arms

The nail test is often mentioned. The thing with these ammo tins is that there have been reports of ammo passing the nail test but tins having some rounds that were corrosive mixed in with non-corrosive, so ....


some people say treat anything in a can as corrosive .. nail test or not ... you won’t be testing every round after all.

Pic of base of cartridge would help. Tin looks very well built not like Chinese slobber soldered tins and I don’t remember much Chicom 7.62x39 coming in stripper clips. More of a Soviet eastern bloc thing. Thinking commercial/ military NATO production from Europe. —Dieseldog!

BYOS - bring your own strippers,

Early Polytech import?

You should 100% treat it as corrosive, which is not an issue, just clean your gun. Time spent figuring out what it is takes away from shooting time??

Oh wahhhhhhh. Takes but a few minutes to do a nail test

Of course I never thought about headstamp. I’ll have to see.

No, the OP's ammo is definitely Chinese. Ammo for export was often labeled in English, and also often loaded on 10 round strippers. Forgot about Chinese SKSs?
