The process involves aligning the rifle’s aiming point, as seen through the optical instrument, with the point of impact of the projectile. Accurate performance requires careful adjustment and verification. This adjustment ensures the projectile strikes the intended target at a specific distance.
Properly calibrated sighting mechanisms enhance accuracy, leading to greater success in target shooting, hunting, and other applications. Historically, this procedure has evolved from rudimentary mechanical adjustments to sophisticated laser and electronic calibration methods, reflecting advancements in both firearms and optical technologies.
