The subtension is linear with the distance, for example, at 500 yards, 1 MOA subtends 5.235 inches, and at 1000 yards 1 MOA subtends 10.47 inches. Since many modern telescopic sights are adjustable in half ( 1 / 2 ), quarter ( 1 / 4 ) or eighth ( 1 / 8 ) MOA increments, also known as clicks , zeroing and adjustments are ...
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 ...

Premade table for range estimation showing target sizes, distances and corresponding angular measurements. Angular sizes are given in milliradians, ranges in meters, and target sizes are shown in both in centimeters, millimeters and inches. Many telescopic sights used on rifles have reticles that are marked in mrad. This can either be ...

Example of a ballistic table for a given 7.62×51mm NATO load. Bullet drop and wind drift are shown both in mrad and MOA.. A ballistic table or ballistic chart, also known as the data of previous engagements (DOPE) chart, is a reference data chart used in long-range shooting to predict the trajectory of a projectile and compensate for physical effects of gravity and wind drift, in order to ...

Fig. 2- Geometry of MOA in configuration shown in fig. 1 MOAs have been used in configurations shown in figs. 1 & 3 whereby one or both components can be adjusted. This has varying effects on the focal properties, in general it has been found that smaller focal spot sizes are apparent when MOAs are used as shown in fig. 1 with only the second ...
