Requirements for Replacement of Currently Issued 5.56 M-855 and 7.62 M-80.

[Tony Williams]

Since the sole purpose of replacing the 7.62mm is to reduce its weight (its performance is fine), and the more the performance exceeds that of the M80 the heavier the cartridge will be, my view is that the new round should match, as closely as possible, the trajectory and wind-drift of the M80 at long range. The round should be the lightest which can achieve that.
