I shoot wolf, and have since the clinton ban dried up all the true military 7.62x39 surplus. back in the early nineties, I would tear through cheap steel core stuff. I've shot the american brands, as others mentioned above. It is nice stuff, but it is SOOOO much more expensive.
And remember... AK's and sks rifles are known to be very forgiving. They can shoot just about anything, so don't worry much. Just avoid the word corrosive, unless shooting in sub-zero environments (one of several reasons the russians used a lot of corrosive ammo is because they say it's more reliable in really cold climates).
