acted upon by the pressure wave the release of undamaged sub projectiles 20 occurs in a time delayed practically trouble free manner upon release from the projectile sub projectiles 20 may continue to fly in an individually spin stabilized manner at an acute angle of departure the arrangement of payload 5 within the projectile greatly improves a dispersion pattern of the payload upon release the present invention takes advantage of the fact that through the action of the detonated opening charge the payload chamber opens essentially along a casing line similar to a zipper from the bottom to the top a particularly advantageous dispersion pattern or distribution of the sub projectiles 20 may be achieved if sub projectiles are used particularly when several are stacked flush on top of one another to constitute the payload columns the opening of the payload chamber 4 begins at the bottom bridge 7 and continues toward the top cap 2 during the opening of the payload chamber 4 the spin stabilized projectiles 20 rotate around the projectile axis resulting in the fact that the sub projectiles 20 of a column 21 are not released at the same time but that the bottommost sub projectiles may exit the payload chamber first whereupon the other sub projectiles of the same column follow at regular time or angular intervals until the topmost sub projectile has left the payload chamber 4 as the last sub projectile with the sub projectile distribution achieved in this manner sub projectiles of one column essentially reach an at least approximately circular arc as shown in fig3 accordingly owing to the continuing opening of the payload chamber 4.
