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.

[ What is claimed is:] [1.]1. In a reduced propellant ammunition cartridge including:a cylindrical case defined by a rear end portion having a primer cap and a flash hole centered therein, a front end portion having a predetermined inside diameter, a powder chamber of diameter greater than said predetermined inside diameter and a tapered neck portion integrally joining said front end portion to said powder chamber anda cylindrical projectile having a portion ceased in said front end portion of said cylindrical case,the improvement which comprises:a pliable tube defined by a proximal end, a distal end and a central body portion integrally joining said proximal end to said distal end,said distal end and central body portion of said pliable tube having an outside diameter slightly less than said predetermined inside diameter,said pliable tube being enclosed by and axially aligned with said cylindrical case with said distal end engaging said rear end portion and encircling said primer flash holesaid pliable tube being of predetermined length that said proximal end thereof, extends to said tapered neck portion with said proximal end portion being expanded into engagement with said tapered neck portion, anda propellant charge solely contained within said ammunition cartridge inside said pliable tube by said rear end portion at said distal end and said projectile at said proximal end.
