outerlimits Posted April 21, 2008 Share Posted April 21, 2008 trying to do some ballistic matching for loads for an 18" barrel, but can't seem to confirm the muzzle velocity of the 62 grain M855 ball coming out of an M4 (14.5" barrel). i'm finding data anywhere between 2,910 and 2,970 fps. anyone got more accurate data?

busyhawk Posted April 21, 2008 Share Posted April 21, 2008 According to NACSEA Warfare Center at Crane the M855 velocity at 15ft. is 3,080 from an M4. I have the ballastic chart but it does not give muzzle velocity. 50 yards 2912.8 100 yards 2751.8 150 yards 2596.6 200 yards 2447.1 and on ... The 77 grain (AA53) is a little slower, 2,770 at 15ft. 50 yards 2630.7 100 yards 2496 150 yards 2365.7 200 yards 2239.7 Anything to help...or confuse.
