When I first got my bushmaster about a year ago I put 500 rounds of wolf through it without issue. Recently I brought what I had in my safe (some russian brand cheapos) and bought another 100 rounds of Wolf and went to the range with my brother...the AR screamed through the russian stuff but choked on the Wolf. Rounds failed to load and when they did, the shell would extract but a new round wouldn't load. I loaded them manually for about 5 rounds but then the next round fired but I could not manually extract it. The bolt was "stuck". After dissasembling it I had to force the bolt out and then force the shell out of the barrel with a cleaning rod with quite a bit of force. There didn't appear to be any damage so I put it back together and the action was great.
So, I went back to the local gun shop and bought 4 different manufacturers of .223. For wolf I bought a box of 55grain and 62 grain .223. Went to the range. Everything but wolf screamed through the AR without incident. All the wolfs acted as they did before..not feeding and I almost got it as nastily stuck again. The other thing I noticed on the spent casings is a slight malformation on the head of the shell..not sure what that is but the other manufacturers ammo did not have such a mark. I have to dispose of the wolf ammo. This isn't scientific proof, but it does seem to indicate there is something going on at wolf.
