Abstract
Abstract A cartridged ammunition for machine weapons, particularly for automatic weapons comprises a combustible casing composed of a casing cover, a cylindrical casing jacket and a casing base, glued to one another at annular contact regions and enclosing a propelling charge. The cartridged ammunition is manufactured by securing the tail section of the projectile in a recess of the casing cover and gluing the tail section thereto, axially inserting the projectile and casing cover into the cylindrical casing jacket through a rear open end thereof and gluing the casing cover to an inwardly extending radial shoulder of the casing jacket, filling the casing with the propelling charge and closing the rear open end of the combustible casing by gluing the casing base to the casing jacket.
