  2. M16 rifle - Wikipedia

    en.wikipedia.org/wiki/M16_rifle

    This concurs with the pre-M16A2 maximum effective range of 460 m (503 yd). [112] The Colt 3×20 telescopic sight was factory adjusted to be parallax-free at 200 yd (183 m). [ 113 ] [ 114 ] In Delft, the Netherlands Artillerie-Inrichtingen produced a roughly similar 3×25 telescopic sight for the carrying handle mounting interfaces.

  3. Point-blank range - Wikipedia

    en.wikipedia.org/wiki/Point-blank_range

    [1] [2] For targets beyond-blank range, the shooter will have to point the barrel of their firearm at a position above the target, and firearms that are designed for long range firefights usually have adjustable sights to help the shooter hit targets beyond point-blank range. The maximum point-blank range of a firearm will depend on a variety ...

    Note ****: The maximum range of a small-arms projectile is attained at about 30° elevation. This maximum range is only of safety interest, not for combat firing. [14] The M16 rifle is "accurate beyond description". [171] Its light recoil, high velocity, and flat trajectory allow shooters to take headshots out to 300 meters.

  5. Rifleman's rule - Wikipedia

    en.wikipedia.org/wiki/Rifleman's_rule

    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. Assume that a range finder is available that determines that the target is exactly 300 meters distance. 2. Determine the elevation angle of the target.

  6. Miller twist rule - Wikipedia

    en.wikipedia.org/wiki/Miller_twist_rule

    Miller twist rule is a mathematical formula derived by American physical chemist and historian of science Donald G. Miller (1927-2012) to determine the rate of twist to apply to a given bullet to provide optimum stability using a rifled barrel. [1]

  7. 16-inch/50-caliber Mark 7 gun - Wikipedia

    They fired projectiles weighing from 1,900 to 2,700 lb (860 to 1,220 kg) at different muzzle velocities, depending on the projectile. When firing armor-piercing projectiles, their muzzle velocity was 2,500 feet per second (760 m/s) with a range of up to 24 mi (39 km). At maximum range the projectile spent almost 1 + 1 ⁄ 2 minutes in flight ...

  8. Mathematical discussion of rangekeeping - Wikipedia

    en.wikipedia.org/wiki/Mathematical_discussion_of...

    The calculation of angular rate requires knowledge of the target and own ship course, speed, and range. The prediction of azimuth [ 21 ] is performed similarly to the range prediction. [ 1 ] Equation 5 is the fundamental relationship, whose derivation is illustrated in Figure 4.

  9. Ballistic coefficient - Wikipedia

    en.wikipedia.org/wiki/Ballistic_coefficient

    The 6 mm and 6.5 mm cartridges are probably the most well known for having high BCs and are often used in long range target matches of 300 m (328 yd) – 1,000 m (1,094 yd). The 6 and 6.5 have relatively light recoil compared to high BC bullets of greater caliber and tend to be shot by the winner in matches where accuracy is key.
