Zero range

If the sight of a gun is set in a way that the intended target is hit at a fixed range. ("zero range").

Energy

The kinetic energy of an air gun pellet depends on the mass and the instantaneous velocity of the pellet.

Velocity

The muzzle velocity depends on two factors: The muzzle energy of the weapon and the mass of the air gun pellet. The ballistic coefficient (BC) describes the drag deceleration of the air gun pellet. This deceleration depends on the shape, mass, and cross-sectional area of the pellet.

Ballistic curve

The ballistic curve of an air gun pellet describes the trajectory of the pellet after it leaves the barrel. The trajectory depends on many factors: muzzle velocity, firing angle, mass of the pellet, gravity, and air resistance.
