The zero range, , is important because corrections due to elevation differences will be expressed in terms of changes to the horizontal zero range. For most rifles, is quite small. For example, the standard 7.62 mm (0.308 in) NATO bullet is fired with a muzzle velocity of 853 m/s (2800 ft/s).
In contrast to most other eye glasses, shooting glasses usually only have one lens that corrects the ametropia of the dominant eye, which is used for aiming.This lens is selected in such a way that the maximum visual acuity lies on the font sight line element near the muzzle of the (non-magnifying) open type or diopter and globe type match sight line elements to get three points positioned in ...
Handguns are typically less accurate; at a shooting distance of 25 yd, a grouping is considered acceptable for self-defense if the shots fall within a circle of 4 to 5 inches, which is 15 to 19 MOA (equivalent to a grouping of 100-150 mm at 25 meters, which is 4-6 mils), [9] representing the shot pattern needed to hit the vital organs of a ...
Mistakes in estimation compound over distance and can decrease lethality or cause a shot to miss completely. [9] [page needed] Snipers zero their weapons at a target range or in the field. This is the process of adjusting the scope so that the bullets' points-of-impact are at the point-of-aim (centre of scope or scope's cross-hairs) for a ...

The major components of sniper equipment are the precision sniper rifle, various optical scopes and field glasses, specialized ammunition and camouflage materials for the sniper’s body and equipment.
Because when using a telescopic sight, the crosshair lines geometrically resemble the X- and Y-axis of the Cartesian coordinate system where the reticle center is analogous to the origin point (i.e. coordinate [0,0]), the designated sighting-in point is known as a zero, and the act of sighting-in is therefore also called zeroing.
