He was telling me how the 5.56mm match-grade rifles they were using at 1000 meters (with 77 gr projectile) would barely "plop" through the target cheese cloth and paper, and wouldn't have any energy left after impact. They tried using them for a period of time and went back to the M14 NM rifles they'd been using prior.
I don't know how long ago that was as I didn't ask, but I thought it was pretty interesting stuff. He said the 77 gr rounds had to be loaded singly, as they were too long to fit in the magazine.
What about this one?
In one of the best kept secrets of National Match history, the Army Marksmanship Unit has been shooting AMU-built National Match grade AR-10's for the past two years. Their work has culminated with the acceptance of the AR-10NM for use "across the board" in NRA Service Rifle competition.
