A document containing a target designed to facilitate the process of adjusting a firearm’s sights so that the point of impact of the projectile coincides with the point of aim at a distance of 36 yards, and typically saved as a Portable Document Format file. The document often includes markings to aid in the accurate aiming and evaluation of shot placement, and may be printed for practical application at a shooting range.
The practice of establishing a “zero” at a specific distance offers several advantages, including simplification of ballistic calculations at varying ranges, allowing for quicker target acquisition, and improving accuracy during engagements. Selecting a 36-yard distance balances ease of use with practical applicability for specific firearms and intended applications. Historical context involves the evolution of sighting systems and a desire for efficient methods of adjusting sights on firearms without excessive ammunition expenditure.
