  • means for moving said chamber between a loading position outside of said breech and into a firing position within said breech;

    means for delivering a new round from said magazine to said chamber in said loading position; and

    means for discharging a spent round from said chamber;

    said chamber being operatively connected to said moving barrel in recoil and counter-recoil, said chamber moving means, said spent round discharging means and said new round delivering means all being actuated directly by said weapon recoil and counter-recoil movement, said new round being held stationary relative to the frame while the barrel and chamber are moved relative to the frame in such counter-recoil over the new round to envelope the new round fully into the chamber, said chamber moving means including a track having multiple ramps interconnected by upper and lower horizontal runs, said track having a first path parallel to the direction of gun barrel movement in recoil for guiding the chamber rearwardly aligned with the barrel until near the end of recoil so that the chamber retains gases in the barrel until dissipated, said chamber having forward and rearward guide members seated in said track, said guide members following said track to lower the chamber along said ramps during recoil and following said track to raise the chamber along said ramps back into said breech during counter-recoil.
