I read that these won't cycle wolf.  If this is true what ammo should I get.  What about the Yugoslavian 7.62x39 from AIM surplus? will this work?

I don't see why they wouldn't cycle Wolf....that's what I like about SKS's and AK's, they eat nearly anything and everything you feed em. But the Yugo ammo is supposedly good stuff. I would make sure that it is the 1980's surplus though. It is non-corrosive where much of the 70's stuff is corrosive. But if your rifle has the chrome bore, it shouldn't matter much. Always clean them well after shooting just in case. I have got my hands on more than one round that was supposedly non-corrosive that was!
