  2. Rifleman's rule - Wikipedia

    en.wikipedia.org/wiki/Rifleman's_rule

    Assume a rifle is being fired that shoots with the bullet drop table given in Table 1. This means that the rifle sight setting for any range from 0 to 500 meters is available. The sight adjustment procedure can be followed step-by-step. 1. Determine the slant range to the target.

  3. Diopter sight - Wikipedia

    en.wikipedia.org/wiki/Diopter_sight

    Target shooting diopter of a 10 metre air rifle with a mounted semi-transparent occluder for the non-aiming eye. A diopter sight is an aperture sight component used to assist the aiming of ranged weapons, mainly firearms, airguns, and crossbows. Diopters function to precisely align the shooter's eye with the front sight and the target, while ...

    en.wikipedia.org/wiki/Gun_laying

    However, in the 1930s the British adopted calibrating sights in which range was set on the sight, which automatically compensated for the difference of muzzle velocity from standard. An alternative to this was a 'gun rule' at each gun; in this case the range was set on the rule and an elevation angle read and given to the layer to set on the sight.

  5. ISSF 10 meter air rifle - Wikipedia

    en.wikipedia.org/wiki/ISSF_10_meter_air_rifle

    A typical 4.5 mm (.177 in) 10 m air rifle match pellet. For the 10-meter air rifle and air pistol disciplines, match-grade diabolo pellets are used. These pellets are wadcutter, meaning the pellet head is nearly completely flat. This leaves smooth-edged round holes in paper targets and allows easy gauging for scoring. Match pellets are offered ...

    To set range the dial adjusts the reticle size to match target wingspan. Currently set to the Junkers Ju 88 , it ranged in size from the large Fw 200 Condor to the small Messerschmitt Bf 109 . A gyro gunsight (G.G.S.) is a modification of the non-magnifying reflector sight in which target lead (the amount of aim-off in front of a moving target ...

  7. Globe sight - Wikipedia

    en.wikipedia.org/wiki/Globe_sight

    A globe sight is a front sight component used to assist the aiming of a gun/device, usually those intended to launch projectiles, such as firearms, airguns, and crossbows. It is found in particular as a front sight element on rifles. To obtain a usable sighting line, the diopter has to have a complementing rear sight element.

  8. Sighting in - Wikipedia

    en.wikipedia.org/wiki/Sighting_in

    After sights have been adjusted to reliably place bullets on target at the desired range, several shots are fired to form a group for measurement of averaged bullet placement. Each bullet position is measured horizontally and vertically from the point of aim, and sights are adjusted to compensate for the mean horizontal distance and mean ...

  9. Point-blank range - Wikipedia

    en.wikipedia.org/wiki/Point-blank_range

    The first mass-produced assault rifle, the World War II StG 44, and its preceding prototypes had iron sight lines elevated over the bore axis to extend point-blank range. The current trend for elevated sights and flatter shooting higher-velocity cartridges in assault rifles is in part due to a desire to further extend the maximum point-blank ...
