Abstract
The target-effective mass of cartridged ammunition is increased while maintaining a predetermined cartridge length. A projectile body has a projectile tail portion extending rearwardly on which a fin or wing-stabilization arrangement is mounted. This tail portion extends rearwardly towards the immediate vicinity of the propellant charge casing bottom. A projection extends rearwardly past the wing or fin-stabilization guide arrangement. This projection includes a massive portion which separates at firing from the propellant charge casing bottom. The rear portion of the projectile body is surrounded by a sheathing of combustible material forming the ignition element which sheathing extends from the cartridge case bottom up to at least the middle of the propellant charge casing and has a longitudinal extent l.sub.2. The massive projection permits, during the combustion of the propellant charge up to separation the build up of a high gas pressure, whereby in particular a loose powder propellant charge is ignited by the ignition element for a short period of time in a uniform and reproducible manner. Thus, without increasing the length of the cartridge an increase of the target-effectiv…
