The wolf ammo I had wouldn't work worth a crap in my Bushy/RRA combo, my Bushy DPMS combo, and now my Oly Arms M4gery. In addition to getting cases stuck in the chamber, you get wildly inconsistant velocity and accuracy. With an SD of nearly 200fps, I shudder to think about how variable the rest of the operations are. In a sound gun with chrome bore, chrome chamber, and well-maintained I'm sure you could shoot cases of it. My experience is anecdotal with three AR's, and my mini-14 and the G36C I shot some out of ate the stuff up.
Yes, I did chrony a bunch of rounds and ended up with an SD of 193fps. That means that one shot may go 2900fps while the next would be 2707 fps. That's with the 62gr stuff.
CRAP, CRAP, CRAP.
