Approximate ballistics formulas for spherical pellets in free flight
Defence 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
