Lead (weapon)

from Wikipedia, the free encyclopedia

The lead is the angle difference for the direct shot between the target direction, which is necessary for hitting a moving target with a firearm , and the target direction, which would be necessary in the same situation for hitting the same target if it were not moving. Since projectiles of a firearm can no longer be controlled after being fired, a change in the course or speed of the target can lead to the target being missed, even with a correctly selected lead.

The size of the lead results from the course and speed of the target, the speed of the projectile and, if applicable, the direction of movement and speed of the shooter. For targets with a straight course and projectiles with constant velocity, the point can be calculated geometrically or with basic trigonometric functions. For targets with a more complicated course and ballistically moving projectiles with decreasing speed, the calculation is considerably more difficult. The lead can be specified as an angle measure (e.g. in a line ) or as a projected distance (e.g. in meters) in the direction of movement of the target.

In the case of military weapon systems , the lead is mostly determined by calculating the firing boards and the current situation, controlled by fire control systems and, if necessary, supplemented by shooting in. In the case of handguns , the lead is usually based on the shooter's experience . This ability of the shooter is trained for sporty target shooting or for hunting practice shooting.

The lead for moving targets must be distinguished from the basic stopping point when aiming at targets.
