A projectile having a conical wall interconnecting a rearwardly opening pyrotechnic cavity and the base of the projectile that is located substantially at the rearward peripheral or sidewall surface of the projectile. The discharging gases from the relatively small pyrotechnic will exit along the conical wall of the launched spinning projectile and minimize the base drag effect of the environmental air stream during projectile flight.
