• (b) a gun barrel and means detachably connecting reward 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 mens 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 position 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 which includes shell feeding means for moving a shell into the shell pickup position rearwardly of said shell loading position, and further include shell rammer means for ramming shells forwardly from the pickup position into the chamber aperture when the chamber is in the shell loading position, the shell rammer means including a rammer body having a forwardly extending shell rammer fixed thereto, and including means mounting the rammer means in the receiver for axial sliding movement between a rearwardmost position in which the shell rammer is rearward of a shell in said pickup position and a forwardmost, battery position in which the shell rammer is rearwardly adjacent the chamber when the chamber is in the shell loading position said means for causing movement of the chamber carrier from its forwardmost position and its rearwardmost position also causing simultaneous movement of the rammer means from its forwardmost position back to its rearwardmost position and including means for causing movement of the shell rammer means forwardly from its rearwardmost position to its forwardmost position independently of forward motion of the chamber carrier from its rearwardmost position to its forwardmost position;
• (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.

• (f) means responsive to firing of the gun 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 forwardly from a shell pickup position into the chamber aperture when the chamber is in the shell loading position which includes shell feeding means responsive to movement of the chamber from the shell firing position to the shell loading position for advancing a shell from an associated shell supply into a position rearwardly adjacent to, and in axial alignment with, the chamber aperture when the chamber is in the shell loading position and including means defining a fired shall casing discharge position forwardly adjacent to, and axially aligned with, the chamber aperture when the chamber is in the shell loading position and including shell ejecting means responsive to movement of the chamber from the shell firing position to the shell loading position for moving a fired shell casing from said discharge position to an ejection port of the receiver for ejection thereof;
• (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.

A gun for firing cylindrically-shaped, telescoped shells, the gun comprising:

• (a) a receiver having means defining a shell feeding port and a fired shell casing ejection port, adjacent ends of said shell feeding and casing ejection ports being longitudinally spaced apart a distance equal to at least about the length of shells fired by the gun, said receiver further including means defining a shell ramming position in shell transfer communication with the shell feeding port and mens defining a fired shell casing discharge position in shell casing transfer communication with the shell ejection port, said shell ramming position and said shell casing discharge position being axially aligned;
• (b) a gun barrel and means for detachably connecting a rearward end region of the barrel to forward regions of the receiver, and with a bore axis laterally offset from the shell ramming and shell casing discharging positions;
• (c) a shell chamber having means defining a cylindrical shell-holding aperture sized to hold a cylindrically-shaped, telescoped shell to be fired by the gun;
• (d) means for mounting the shell chamber in the receiver intermediate the shell feeding and casing ejection ports for lateral movement between a shell loading position in which the shell holding aperture is between, and is axially aligned with, the shell ramming and fired casing discharging positions and a shell firing position in which the shell-holding aperture is axially aligned with the barrel;
• (e) means for causing movement of the shell chamber between the shell loading and the shell firing positions;
• the means for causing movement of the chamber between the shell loading position and the shell firing position include a chamber carrier, means for mounting the chamber carrier in the receiver for axial sliding movement between a forwardmost, battery position and a rearwardmost position, including means for interconnecting the chamber carrier and the chamber so as to cause the chamber carrier is in the battery position and so as to cause the chamber to be in the shell loading position when the chamber carrier is in the rearwardmost position, and further including means of causing the chamber carrier to move between the battery position and the rearwardmost position,
• (f) means for ramming a shell from the shell ramming position into the chamber shell-holding aperture when the chamber is in the shell loading position, thereby also causing a fired shell casing held in the chamber aperture to be pushed out therefrom into the fired casing discharging position;
• and
• (g) means for firing a shell held in the chamber shell holding aperture when the chamber is in the shell firing position, the shell firing means including a firing pin connected to the chamber carrier in a position causing the firing pin to impact and fire a shell held in the chamber aperture when the chamber carrier moves forwardly into the battery position thereby causing the chamber to be moved into the shell firing position.
