Let's see what I can recall about Wolf and the horror stories of the lacquered ammo sticking:
Wolf used to sell a bunch of ammo with lacquer sealer. Some folks would run a bunch of rounds though an AR15 fast, then stop shooting with a round in the chamber. Once the gun sat for a bit, that round was "thermal glued" into the chamber. From what I can gather, AK variants didn't much care; they will digest anything.
My guess is that only certain AR's had the problem. Chamber dimensions vary; one guy has a tight match chamber and another has a loose mil-spec chamber.
But Wolf got the message and switched away from that red laquer we used to see; they started producing "slippery" polymer coated ammo.
If any ammo, Wolf or other, is not extracting from your gun, it's time to change brands, change loads, find out for sure if it's the ammo.
But in general, and certainly for my pistols, I think Wolf ammo is fine for practicing. It goes bang.
