Definitions

• This disclosure relates generally to a feedback display for a riflescope.
• One factor may be bullet drop, which is caused by the influence of gravity on the moving bullet, and is characterized by a bullet path which curves toward earth over long ranges. Therefore, to hit a target at long range, it is necessary to elevate the barrel of the weapon, and the aiming point, to adjust for bullet drop.
• Other factors such as wind, Magnus effect (i.e., a lateral thrust exerted by wind on a rotating bullet whose axis is perpendicular to the wind direction), projectile design, projectile spin, Coriolis effect, and the idiosyncrasies of the weapon or projectile can change the projectile's path over long range. Such effects are generally referred to as "windage" effects.
