DO NOT shoot Wolf if you value your firearms rifling. Some of its alright, but if the bullet sticks to a magnet, find something else. That means its just a copper washed steel round. Even though it may have a lead core, its still rather hard.
I've seen a couple AR barrels that were destroyed by shooting nothing but Wolf.
But if its just some kind of cheap rifle or whatever, by all means, go for it. I shoot Wolf through my SKS.
