[QUOTE="orkan, post: 2976179, member: 25377"] Correct, I'm seeing very similar barrel life, with several thousand rounds of sub-1/4moa performance when using heavy bullets. The first round hit percentage in the dog town out here on the prairie is much much higher with .22cal bullets in the 75-80gr weight range than the light bullets. A 26" 22BRA running a 75 eldm at 3050fps is ultra mild, and can be shot to the cadence of 30+ rounds per minute before being allowed to cool, with no averse affects to precision, accuracy, or barrel longevity. At this speed, the brass is virtually indestructible and I have no idea how many firings it would actually take to ruin it. At 3150fps, brass life is diminished, but it's still usually good for well over 50-60 firings. A .223 based case can not even remotely approach the same kind of efficiency, forgiveness, and longevity of the BRA platform. ... and I would know, because I once had a fleet of .223AI, .20-223AI, etc. etc. etc. Not to say the .223 based stuff is bad. It's just when compared to the 22BRA... it's no contest. Just to prove this isn't some sort of anti-.223 case bias... here's a video with one of my .20-223AI's from recent years. They are great. They just can't hang with the BRA's at all.
