Will 7.62x39 stamping tell if it is corosive?

[SKS-Stu]

I have a bunch of 7.62x39, does the stamping on the back of the bullit case indicate if it is corrosive or not? Mine are stamped 71 and 95 under it. Thanks

Is it military surplus? If it is, likely corrosive. Brand? What packaging did it come in? Where did you buy it?

Assume it is corrosive and have fun shooting it

 

[CanAm]

likely non corrosive. How is it packed?

Best to assume it is corrosive, and just clean your gun after using it.

If you assume it's corrosive the only negative if it isn't is you will have a cleaner rifle.
If it is corrosive and you assume it isn't you can have a rusty rifle.

Over the years I have bought corrosive and non corosive and this ammo is not in the original packaging.

Hmm 1995 production Chinese is usually non corrosive... Is it a dark case, almost black?

OP didn't say if some where 71 and some where 95 or if they both 71 and 95 on the same case. Considering the date of most surplus ammo I'd say more likely 1971 than 1995.
A lot of the surplus I've shot has had two numbers on it. Normally only one makes sense for a year (such as 14 and 73; obviously 1973) but with 71 and 95, if on the same case, not sure which is the date.

OP said they are marked with both "71 and 95 under it", also he did not say specifically it was surplus. I believe in this case the 71 is a factory number and the 95 is the year.

It is non corrosive.
Just checked my Norinco silver box stuff and it has the same headstamp.

Those are some of the better x39 i have shot. Non corrosive and never had failure with them.

I recently found two 1200rd crates of this stuff packed in silver boxes. 71 over 95 head stamp. Lead core

 

[wbaad]

Same stuff I have. Damn good stuff and I have proven it non corrosive. Lots of soot, but no rust

 

[FreedomIsn'tFree]

Yup, the silver box stuff is great. I have shot a crate of it already and no rust, I just wish I would have bought a few more crates than I did.

Yes the case is a very dark grey/ black.

Thanks, good to know.
