A self-powered, belt-fed automatic gun for firing cylindrical, telescoped ammunition is described. Mounted in receiver portions of the gun, to which a barrel is connected, are a shell chamber, a chamber carrier assembly, a shell rammer assembly and shell feeding and casing ejecting assembly. The shell rammer and chamber carrier assemblies are mounted in the receiver for axial reciprocating movement, the chamber being interconnected with the carrier assembly so that recoil movement of the carrier assembly moves the chamber laterally from a firing position to a loading position, counterrecoil movement of the carrier assembly causing the chamber to move back to the firing position. Responsive to chamber movement from the firing position to the loading position a shell is moved into a feed position rearwardly adjacent to the chamber. Searing means are provided for enabling the rammer assembly to move forwardly in counterrecoil in advance of the carrier assembly, the rammer assembly ramming a shell from the feed position into the chamber, and thereby ramming a fired shell casing from the chamber into a forwardly adjacent ejecting chamber, before the carrier assembly is released for counterrecoil movement. A firing pin mounted on the carrier assembly causes firing of a shell in the chamber when the carrier assembly reaches its battery position.

A gun for firing cylindrically-shaped, telescoped ammunition, the gun comprising: (a) a receiver; (b) a gun barrel and means detachably connecting rearward end regions of the barrel to forward regions of the receiver; (c) a shell chamber having formed longitudinally therethrough a cylindrical, telescoped shell-holding aperture sized to receive a cylindrical, telescoped shell having a projectile and a shell casing and means mounting the chamber in the receiver rearwardly of the barrel for linear sliding movement in a direction orthogonal to the bore axis of the barrel between a shell-loading position in which the shell-holding aperture is out of axial alignment with the bore through the barrel and a shell firing position in which the shell-holding aperture is axially aligned with the barrel bore; (d) a chamber carrier and means mounting the chamber carrier in the receiver for axial sliding movement between a forwardmost, battery position and a rearwardmost position; (e) means for interconnecting the chamber with the chamber carrier so as to cause the chamber to be in the shell loading position when the chamber carrier is in the rearwardmost positions and to be in the shell firing position when the carrier is in the forwardmost, battery position; (f) means responsive to firing of the gun for causing movement of the chamber carrier from the forwardmost, battery position to the rearwardmost position; (g) means responsive to actuation of a trigger for loading a shell into the chamber aperture when the chamber is in the shell loading position and for simultaneously pushing a fired shell casing forwardly out of said chamber; (h) means responsive to actuation of the loading means for causing the chamber carrier to move from its rearwardmost position back to its forwardmost position; and (i) means for causing firing of a shell held in the chamber aperture when the chamber is in the shell firing position.
