I have seen Wolf ammo shot in 4 different ARs. It all seemed to function well and shot well. But no rapid fire was done with any of the rifles, just targets and plinking steel. We found that the Wolf, although accurate enough, did not have as much knock down power on the steel targets as the other ammo shot that day. SA, Win, ETC. Also, everyone aggreed they did not like the build up in the chamber and on the bolt face. Two of the people that I shoot with decided they could live with the Wolf ammo, and the other two decided we could live without it. They bought our remaining stock of it and we are all happy shooters.
I'm from the old school, I like brass cases and stuff made in the USA by Americans. And before you all jump on that statement, no, I don't always buy american goods, but I do when I can, and you all should too. Cheers! Phil
