External ballistics or exterior ballistics is the part of ballistics that deals with the behavior of a projectile in flight. The projectile may be powered or un-powered, guided or unguided, spin or fin stabilized, flying through an … See more

Projectile/bullet drop and projectile path
The effect of gravity on a projectile in flight is often referred to as projectile drop or bullet drop. It is … See more

Gyroscopic drift (spin drift)
Gyroscopic drift is an interaction of the bullet's mass and aerodynamics with the atmosphere that it is flying in. Even in completely calm air, with no sideways air movement at all, a spin-stabilized projectile will … See more

The maximum practical range of all small arms and especially high-powered sniper rifles depends mainly on the aerodynamic or ballistic … See more

When in flight, the main or major forces acting on the projectile are gravity, drag, and if present, wind; if in powered flight, thrust; and if guided, … See more

Wind
Wind has a range of effects, the first being the effect of making the projectile deviate to the side (horizontal deflection). From a scientific … See more

Though not forces acting on projectile trajectories there are some equipment related factors that influence trajectories. Since these factors … See more
