User blog comment:Brothertim/Why does IW not use bullet drop over long ranges, or have delay?/@comment-242630-20100128154517

Bullets travel at very high velocities, usually around 1,100 m/s. Assuming the bullet is fired from eye level when crouched (height 1 meter), it would take about .452 seconds to hit the ground. In that .452 seconds at 1,100 m/s it would travel about 500 meters. Now 500 meters is no short distance at all; probably longer than the length/width of any of the multiplayer maps. So even for the most long-range shots there should be little if any gravitational effects of the bullet.
