You know, I read all the bitching about Wolf ammo on the boards here about how some AR's don't like it, it smells, so on and so forth. I dropped by my local ammo seller and that was all they had, so I figured what the hell. Shot 400 rounds of Wolf, through my Bushy, the first weekend and have gone back for more. Not one failure and it didn't stink any more than WWB. It did leave considerably more soot and crap in the gun, but a few more passes with some patches took care of that. The only problem I had with it is it shot way higher than WWB. About 6 to 8 inches higher. No big deal, couple clicks on the rear sight took care of it, but remember that if you switch back and forth between diff. ammo alot.
I am going to pick up a case of the Wolf in .223 and 9mm this weekend. Haven't tried the 9mm yet, but I don't forsee any problems.
