Out to the distances we care about, the velocity curve given by the 0.151 G7 BC figure accurately represents the real-world velocity curve of M855, under standard conditions. 4.
The 5.56 was designed for the M16, which features a 20 inch barrel, and the bullet uses all of this length to get up to a velocity of 3,000 feet per second. So as the barrel length is decreased, the bullet exit velocity also decreases, since the gases don’t have enough time to get the bullet up to speed before the bullet is expelled.
