Abstract
A cartridge ammunition includes a case having a case bottom; a propellant disposed in the case; a propellant igniter mounted centrally on the case bottom; an arrow projectile having a rear length portion extending into the case towards the case bottom; and a coating of igniting substance applied to at least one part of the surface of the rear projectile length portion. A clearance defined by a distance between a frontal terminus of the propellant igniter and the rear terminus of the rear length portion of the arrow projectile is such that upon igniting the propellant igniter igniting flames emanating from the propellant igniter bridge the clearance and ignite the coating of igniting substance.
