Well...I bought my first AR 9 years ago. Been shooting Wolf ammo through everyone I have ever owned, and it finally happened to me I was trying to sight my AR in when I had a failure to feed, upon closer inspection, it wasn't a failure to feed, it was a failure to eject. The rim of the case was ripped off! It took a while and some taps with a cleaning rod, but I got it out. Then went on with the Wolf ammo and was hitting 6 inch balloons at 300 yards! I am happy with that. I dont have a precision AR platform, just a DoubleStar M4, so I'll def take that kind of accuracy out of something with a $40 scope on it and Wolf Ammo.
