7.62x39mm manufactured in Russia by the Ulyanovsk Cartridge Works factory in 2009-10 but was withheld due to contractual issues with the factory and Wolf. While packaged in a Wolf box and assembled using cases with the "Wolf" head stamp, it does not carry the 100% Satisfaction Guarantee from Wolf due to this. The ammo itself is good to go and shoots just as good as modern production ammo from Wolf.
