So, I have shot a couple hundred rounds worth of .223 wolf in my AR in the past without one single issue. Well, after today, I am totally finished with using anymore of it. I was able to duplicate an empty case seizing up TIGHT in the chamber at the range today. The ammo was also slowing down the BCG enough to where it was not able to strip the next round from the magazine. I barely got through my first box of the crap. I am glad I only bought 3 boxes total. I will probably just give away the rest of it to somebody who can shoot it. I was inspecting the ammo, and I noticed a few things I had not in my previous batch of Wolf. There were mixed match colored primers, and there felt to be little uneven burs on the mouth of the case where it meets the bullet. I did check out the chamber on my rifle with a flash light, and could not see any type of scarring. I just hope it did not cause any sort of problems. It has run 100% up until today.
