![]() ![]() Some of the critical elements involv ed in the study of interior ballistics are the relationshi p of the weight of charge to the weight of projectile the length of bore the optimum size, shape, and density of the propellant grains for different guns and the related problems of maximum and minimum muzzle pressures. Interior ballistics deals with the temperature, volume, and pressure of the gases resulting from combustion of the propellant charge in the gun it also deals with the work performed by the expansion of these gases on the gun, its carriage, and the projectile.

Bullet motion can be categorized into three (3) general types 1) Dire ct moti on – the forwa rd motio n of the bulle t or shots ou t of the shel l by the acti on of the expa nsiv e force of gases from a burning gunpowder 2) Rota tory mot ion – is the acti on of the bull et passi ng throu gh a rifled bor e barrel fir earm whi ch is eith er twist ed to the left or to the right 3) Translational motion – is the ac tion of th e bullet o nce it hit s an obje ct or the target and subsequently ricocheted.
