  2. 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 ...

  3. 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 ...

  4. 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]

  5. 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

  6. Equations for a falling body - Wikipedia

    en.wikipedia.org/wiki/Equations_for_a_falling_body

    A set of equations describing the trajectories of objects subject to a constant gravitational force under normal Earth-bound conditions.Assuming constant acceleration g due to Earth's gravity, Newton's law of universal gravitation simplifies to F = mg, where F is the force exerted on a mass m by the Earth's gravitational field of strength g.

  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 ...

    USS Iowa fires a full broadside, 1984. A gun is a normally tubular weapon or other device designed to discharge projectiles or other material. [ 20 ] The projectile may be solid, liquid, gas, or energy and may be free, as with bullets and artillery shells, or captive as with Taser probes and whaling harpoons .

  9. Terminal ballistics - Wikipedia

    .32 ACP full metal jacket, .32 S&W Long wadcutter, .380 ACP jacketed hollow point For short-range target shooting, typically on ranges up to 50 meters, or 55 yards, with low-powered ammunition like .22 long rifle , aerodynamics is relatively unimportant, and velocities are low compared to velocities attained by full-powered ammunition.
