A process of aligning a rifle’s sights or scope so that the point of impact coincides with the point of aim at a specific distance, typically one hundred yards, is fundamental to accurate shooting. This precise adjustment is typically achieved using a paper or cardboard target with clearly defined aiming points.
This calibration provides a verifiable baseline for accuracy and allows for predictable trajectory compensation at other distances. It enables consistent shot placement, critical for hunting, competitive shooting, and tactical applications. The widespread adoption of this standard distance reflects its practicality for both civilian and military marksmanship training. A properly adjusted sighting system contributes significantly to firearm safety by ensuring projectiles strike the intended target.
