Abstract: Reduced propellant ammunition cartridges, particularly subsonic cartridges for clandestine use of weapons which normally fire supersonic projectiles, include a length of pliable tubing that has an outside diameter just slightly smaller than the inside diameter of the cartridge neck portion that holds the projectile with such tubing having a length that allows it to snugly fit between the base of the cartridge case and the cartridge neck portion. Such a sized tube is inserted through the neck portion and then its distal end is expanded below the cartridge neck portion to be held captive in the cartridge case. The propellant charge is contained inside the pliable tube by the rear end portion of the casing at its distal end and the projectile at its proximal end.

Abstract: A projectile for firing from a self-loading firearm is provided that will rmit the self-loading mechanism to function while delivering a targeting projectile of reduced range and striking capacity. These latter characteristics may be varied in accordance with a designer's preference.
