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

It would appear that a 100 gr 6.5 bullet with a muzzle velocity of 2750 ft/sec from a 20" barrel would do just that.

There are already commercial offerings 100 gr 6.5 velocities with BC's ranging upwards of 0.444, so duplicating the trajectory and wind drift of the M80 in a military-grade 100 gr 6.5 bullet should be tractable.

BTW the Grendel can launch a 100 gr pill at these velocities!

Cheers!
Joe
