Abstract A caseless small arms cartridge including a generally cylindrical solid propellant body having a bullet projecting from the front end thereof with an organic plastic seal ring and link element mounted on the bullet with the bullet projecting forwardly therebeyond. The seal ring has an outer surface of a diameter greater than that of the solid propellant body for providing a seal with a surrounding firing chamber and has an arm portion extending radially outward beyond the ring with a bore for receiving either the bullet of a second like cartridge for assembling a plurality of cartridges to provide a belt thereof or for engaging the loading plunger of the gun breech. The gun for firing such caseless cartridges comprises a receiver element, a barrel mounted therein, a novel floating firing chamber element mounted in the receiver element for limited movement between a loading position away from and a firing position toward the barrel, and firing means for moving the floating firing chamber element to its firing position. The novel floating firing chamber has an enclosed bottom with abutment means thereon for contacting the primer of the cartridge and an open forward end adjacent the barrel for receiving the cartridge body within the chamber with the bullet within the barrel when the floating firing chamber is in its loaded position. The firing means moves the firing chamber to its firing position to drive the abutment means into contact with the primer to fire the cartridge.
In a caseless cartridge including a generally cylindrical solid propellant body having a bullet projecting from the front end thereof, that improvement which consists of: an organic plastic seal ring and link element mounted on said bullet by an interference fit with said bullet projecting forwardly and said solid propellant body rearwardly therebeyond and having an outer surface of a diameter greater than that of said solid propellant body for providing a seal with a surrounding firing chamber, said element having an arm portion extending outwardly from said bullet, said arm portion having a bore for receiving the bullet of a second like cartridge for assembling a plurality of said cartridges to provide a linked belt thereof, said bullet of said second like cartridge being loosely mounted in said bore for rotation therein relatively to said element and said element further including means for rotating said element relatively to said second like cartridge.
