Abstract
A practice projectile for mortars and the like which has a nose fuse mounted on a shell casing. A pyrotechnic charge is disposed in the shell casing. A tail section is mounted in the rear of the shell casing and holds a propellant charge. A percussion cap is mounted in the nose of the projectile and is adapted to be ignited by the nose fuse. A central pipe, having one end opposite the percussion cap, extends from the proximity of the percussion cap to the proximity of the propellant charge in the tail section. The flame from the percussion cap travels through the central pipe and ignites the propellant charge which causes the tail section to be expelled from the rear of the shell casing to thereby expose a rear opening in the shell casing through which the pyrotechnic gases produced by the also ignited pyrotechnic charge are expelled.
