Abstract
A method for aiming a projectile weapon involves identifying a projectile group corresponding to a selected projectile and its nominal initial velocity from at least two different predetermined groups of projectiles, determining a range to a target, and automatically determining an aiming adjustment for aiming the projectile weapon based on the range to the target and a nominal ballistic characteristic of the projectile group. The nominal ballistic characteristic of the projectile group may be characteristic of a ballistic coefficient of the selected projectile and the nominal initial velocity of the selected projectile. Also disclosed are systems and methods for determining hold over aiming data and equivalent horizontal range data, for aiming projectile weapons at inclined targets.
