It is stamped "711" and "93".  123 gr hollow point made in Russia.

No.

As stated above its not corrosive.

I have a little of that ammo left from years gone by, its good stuff.

It is good ammo, but don't try to sight in with it. That stuff was Russia's first commercial 7.62X39 exported to the U.S. That was around 1992 or so and it was about 12 cents a pop. Wolf and their other commercial brands came later.

Maybe!

Some of the very early runs used lots of military primers that were in the production queue.

This was also the case with early commercial hungarian stuff.  I think it was branded kfs.

I am going to agree with this. I shot a lot of the early to mid '90s Russian import x39 (in the '90s ). Most was genuinely "non-corrosive" but some left me with fuzzy red metal in less than 24hrs despite being labeled or advertised as "non-corrosive".

My $0.02; if you have a bunch of this you want to shoot, take it to the range, have fun and collect a number of the empty steel cases. When you get home clean your rifle as you would for "corrosive" primed ammo (just one extra step and a little more attention to the nooks and crannies) and leave the steel cases out in the garage for a few days, periodically examining the INSIDE of the case for rust. If your humidity is extremely low (as it often is in Winter) maybe leave a couple empty cases on your bathroom cabinet (don't even try and explain it to the SO ).
