Approximate ballistics formulas for spherical pellets in free flight

open access: yesDefence Technology, 2018
The ballistics equations for spherical pellets in free flight are simplified through appropriate scaling of the pellet velocity and pellet distance. Two different drag coefficient curves are averaged to yield a single curve applicable to shot pellets and
