In their use, the self-propelled projectiles described and illustrated are typically used in the cartridge or projectile chamber of a conventional Weapon introduced, which is used in terms of holding and ejecting the cartridge or the cartridge Mechanism and possibly also with regard to the arrangement and design of the Schiagbolens is changed in a suitable manner. As can be seen from the drawings, came the blow-out ignition on any wall of the lower annular cavity 4, 24, 34 or 48 for the ignition mixing take place in any sorting, for example at point 10 < on the side ligament, at point 11 would see the bottom, or axially at 12 or inside at 15 " The chosen arrangement of the firing pin depends on the weapon in question.

The impact causes the ignition mixture to be ignited immediately and is then transferred to the propellant charge, be it through the holes 6, 6, 30, 49, which seals the various cavities in them after the rapid destruction or by burning the membrane or Connect disk 38 or other elements separating the cavities © from one another. As a result of the explosion of the propellant charge, the combustion gases escape directly from the rear end of the projectile after the small end cap or membrane 8, 29, 38, 50 has been destroyed by burning or volatilization. The 9 gases then enter the projectile
