Ballistic range compensation for projectile weapon aiming based on ammunition classification
First Claim
1. A method for aiming a projectile weapon that shoots a selected projectile having associated ballistic characteristics, comprising:
- based on at least the selected projectile, identifying a corresponding projectile group from at least two different predetermined groups of projectiles, each group encompassing two or more different types of projectiles having different calibers, each group having associated nominal ballistic characteristics;
sighting-in the projectile weapon at a predetermined first range so that a primary aiming point of an aiming device associated with the projectile weapon is superposed with a nominal point of impact of a projectile when shot from the projectile weapon at the first range;
after sighting-in the projectile weapon, determining a range to a target;
based on the range to the target and the nominal ballistic characteristics of the identified projectile group corresponding to the selected projectile, determining an aiming adjustment for the projectile weapon; and
using the aiming device, aiming the projectile weapon based on the aiming adjustment.

Abstract
A method for aiming a projectile weapon may utilize an aiming device having a primary aiming mark adapted to be sighted-in at a first selected range and one or more secondary aiming marks spaced below the primary aiming mark, and includes identifying, from at least two different groups of projectiles, a projectile group corresponding to a selected projectile. An aiming adjustment for the projectile weapon is determined and effected based on the range to the target and the nominal ballistic characteristics of the identified projectile group corresponding to the selected projectile. Other methods of aiming include identifying one projectile group from two or more predetermined projectile groups based on a selected projectile. Each predetermined projectile group preferably includes two or more different projectiles, preferably of different calibers, and a projectile having ballistic characteristics that are approximately median for each such projectile group.

10. A method for aiming a projectile weapon that shoots a selected projectile having associated ballistic characteristics, comprising:
-
obtaining a list of multiple types of projectiles and associated predetermined projectile groups, wherein each predetermined projectile group encompasses two or more of the types of projectiles on the list having similar ballistic characteristics including at least two such types of projectiles having different calibers, each projectile group corresponding to one of several predetermined ballistic compensation settings; from the list, identifying one of the ballistic compensation settings corresponding to the selected projectile; determining a range to a target; based on the range to the target and the identified one of the ballistic compensation settings, determining an aiming adjustment for the projectile weapon; and aiming the projectile weapon based on the aiming adjustment. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19)
