Lucky Gunner torture tested four AR-15s with 10,000 rounds each of four different loads to assess how the ammunition worked. The guns were treated the same to control for as many variables as possible.
What they found was scary.
The Federal, brass cased ammunition had zero malfunctions and after 10,000 rounds, the rifle was still shooting good groups. That’s good.
Contrast that with Brown Bear ammo Brown Bear also had 9 malfunctions, but notably, after 5200 or so rounds, they had a series of short-stroking failures that were found to be caused by carbon build-up that almost entirely occluded the gas key and gun tube. Also, in just 6000 rounds, the Brown Bear ammunition had completely shot out the barrel, eroding the lands to the grooves. There were also lots of stuck cases at around 8,000 rounds.
The Wolf ammunition also completely shot out the barrel after 6,000 rounds and there were numerous stuck cases.
The Tula ammunition had problems after just 200 rounds and they switched to a different rifle with a larger gas port.
