Ballistic coefficient
Videos
In ballistics, the ballistic coefficient of a body is a measure of its ability to overcome air resistance in flight. It is inversely proportional to the negative acceleration: a high number indicates

External ballistics

External ballistics or exterior ballistics is the part of ballistics that deals with the behavior of a projectile in flight. It deals with projectiles under the influence of a gravitational field; it

…and trajectories. The modern day commercially published ballistic tables or software computed ballistics tables for small arms, sporting ammunition are exterior ballistic, trajectory tables. The 1870 Bashforth tables were to 2,800 ft/s (853 m/s). Mayevski, using his tables, supplemented by the Bashforth tables (to 6…

Typical trajectory graph for a M4 carbine and M16A2 rifle using identical M855 cartridges with identical projectiles. Though both trajectories have an identical 25 m near zero, the difference in muzzle velocity of the projectiles gradually causes a significant difference in trajectory and far zero.[clarification needed] The 0 inch axis represents the line of sight or horizontal sighting plane.
