i only use wolf in 5.45X39 and 7.62X39 and havent had any bad experiences with it, the 5.45 is hard to find in anything but wolf, and all the wolf stuff is cheap, i figured they outta be able to do AK ammo ok, of course its not up to say federal/remington stds, but for the $$ its ok i think. i havent noticed it being particularly dirty or smoky.
