This invention has the provision in an automatic gun having a relatively small diameter barrel cluster, which rotates at a first velocity, of a relatively small diameter stationary cam track which controls and drives the gun bolts through their respective fore and aft dwells and adjacent accelerations and decelerations, and an additional relatively small diameter cam track which rotates in the opposite direction at a multiple of said first velocity to control and drive the gun bolts through the cross-overs of the stationary cam track. |
