  2. Very-low-drag bullet - Wikipedia

    en.wikipedia.org/wiki/Very-low-drag_bullet

    Most VLD bullets are used in rifles. VLD bullets typically have a ballistic coefficient greater than 0.5, although the threshold is undefined. [1] Bullets with a lower drag coefficient decelerate less rapidly. A low drag coefficient flattens the projectile's trajectory and also markedly decreases the lateral drift caused by crosswinds. The ...

  3. Ballistic coefficient - Wikipedia

    en.wikipedia.org/wiki/Ballistic_coefficient

    The ballistic coefficient of an atmospheric reentry vehicle has a significant effect on its behavior. A very high ballistic coefficient vehicle would lose velocity very slowly and would impact the Earth's surface at higher speeds. In contrast, a low ballistic coefficient vehicle would reach subsonic speeds before reaching the ground. [75]

  4. QuickLOAD - Wikipedia

    en.wikipedia.org/wiki/QuickLOAD

    The QuickLOAD interior ballistics predictor program also contains the external ballistics predictor computer program QuickTARGET. QuickTARGET is based on the Siacci/Mayevski G1 model and gives the user the possibility to enter several different BC G1 constants for different speed regimes to calculate ballistic predictions that more closely ...

  5. Ballistic table - Wikipedia

    en.wikipedia.org/wiki/Ballistic_table

    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 ...

  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. Gun chronograph - Wikipedia

    en.wikipedia.org/wiki/Gun_chronograph

    A ballistic chronograph or gun chronograph is a measuring instrument used to measure the velocity of a projectile in flight, typically fired from a gun or other firearm. The instrument is often useful for tasks such as gauging the utility of a firearm or safety of non-lethal projectiles fired from items such as a paintball gun or BB gun .

  8. .416 Remington Magnum - Wikipedia

    en.wikipedia.org/wiki/.416_Remington_Magnum

    It is evident that the .416 Remington Magnum is a ballistically superior cartridge to the .458 Winchester Magnum and has a trajectory close to that of the .375 H&H Magnum. While the .458 Winchester Magnum retains4,000 ft⋅lbf (5,400 J) to about the 65 yd (59 m) the .416 Remington Magnum carries that energy level beyond the 100 yd (91 m) mark.

  9. 6.5mm Creedmoor - Wikipedia

    en.wikipedia.org/wiki/6.5mm_Creedmoor

    The 6.5mm Creedmoor (6.5×48mm), [6] designated 6.5 Creedmoor by SAAMI, 6,5 Creedmoor by the C.I.P. [4] is a centerfire rifle cartridge introduced by Hornady in 2007. [7]It was developed by Hornady senior ballistics scientist Dave Emary in partnership with Dennis DeMille, the vice-president of product development at Creedmoor Sports, hence the name.
