Abstract

A practice projectile such as a shortened range rifle bullet is designed with a ballastic coefficient increased w.r.t. that of the corresponding real projectile to be simulated by inter-relating principal parameters including mass, size and shape of body and warhead and providing means of overstabilizing tape projectile up to an early point in its trajectory, as well as means to increase the aero dynamic coefficient by rotational braking which quickly destabilises the projectile after it passes the early point in the trajectory. Rotational brakin means pref. comprise channels, flutes, grooves milling etc. in the surface of the warhead, partic. longitudinal flutes in th rear end smooth for a length equal to 20% of the overall length of the projectile. The practice projectile is about 20% lighter than the real projectile which it simulates and the centre of gravity is spaced from the cartridge back by about 40% of the overall length of the projectile. Reduced power practice annunition to provide realistic target practice on a rifle range of reduced length. The projectile simulates closely the trajectory of real ammunition and with comparable accuracy. The practice ammunition is reliable and cheap.
