*shrugs* I've had good experience with Wolf ammo. It makes fine range ammo for those of us on a budget (or those who are just economical and don't reload all that much).
Their .45 ACP, 9mm, .308, and .223 work quite well in my XD-45, Glock 19, Browning M1919, and Bushy AR without issues. Sure, the .223's not nearly as accurate as other stuff out there, but it's fine for plinking tin cans with friends at the range. If it jams (which it hasn't), then it's no big deal. The 7.62x39mm has worked very well indeed in my SKS, with only one or two stovepipes out of thousands of rounds fired.
Understand that it's cheap range ammo, but in general it works well. If you've been using it in the past and it continues to work well, excellent. If you've had problems, switch to something else. I've had good experience with it, and will continue using it until it gives me repeated problems.
Their .22LR stuff is actually made in Germany (by SK, I think), and is absolutely fantastic stuff. Definitely not "cheap plinking ammo", but more like "accurate competition ammo". Worth checking out.
Just my $0.02.
