  2. 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]

  3. External ballistics - Wikipedia

    The Excel application then employs custom macroinstructions to calculate the trajectory variables of interest. A modified 4th order Runge–Kutta integration algorithm is used. Like Pejsa, Colonel Manges claims center-fired rifle accuracies to the nearest one tenth of an inch for bullet position, and nearest foot per second for the projectile ...

  4. Rifleman's rule - Wikipedia

    en.wikipedia.org/wiki/Rifleman's_rule

    The rule says that only the horizontal range should be considered when adjusting a sight or performing hold-over in order to account for bullet drop. Typically, the range of an elevated target is considered in terms of the slant range , incorporating both the horizontal distance and the elevation distance (possibly negative, i.e. downhill), as ...

    en.wikipedia.org/wiki/Dive_bomb_(guitar_technique)

    Dive bomb is a guitar technique in which the tremolo bar, or whammy bar is used to rapidly lower the pitch of a note, creating a sound considered to be similar to a bomb dropping. One of the most recognized pioneers of this technique is Jimi Hendrix .

  6. Ballistic coefficient - Wikipedia

    en.wikipedia.org/wiki/Ballistic_coefficient

    The formula for calculating the ballistic coefficient for small and large arms projectiles only is as follows: = [2] where: C b,projectile, ballistic coefficient as used in point mass trajectory from the Siacci method (less than 20 degrees). [3] m, mass of bullet

  7. 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 ...

  9. 12 equal temperament - Wikipedia

    en.wikipedia.org/wiki/12_equal_temperament

    12-tone equal temperament chromatic scale on C, one full octave ascending, notated only with sharps. Play ascending and descending ⓘ. 12 equal temperament (12-ET) [a] is the musical system that divides the octave into 12 parts, all of which are equally tempered (equally spaced) on a logarithmic scale, with a ratio equal to the 12th root of 2 (≈ 1.05946).
