Dual shell feeding apparatus for automatic guns having two shell supplies adapted for holding different types of shells, comprises a shell feeding rotor formed with first and second sets of three peripheral shell holding cavities each, the cavities being arranged in alternating relationship at 60 DEG intervals. The rotor is rotatably mounted between the two shell supplies and a shell pick up position of the gun in a manner causing, when one of the shell holding cavities of either cavity set is in the shell pick up position, another cavity of the same cavity set is in shell receiving relationship with the corresponding one of the shell supplies, shells being fed from one of the supplies by one of the rotor cavity sets when the rotor is selectively rotated in one direction and from the other supply by the other cavity set when the rotor is selectively rotated in the opposite direction. Second stage shell feeding tracks associated with each of the shell supplies are configured for transferring shells into the rotor from the selected supply after first stage shell transferring rotor rotation and before the next firing.
