ABSTRACT:
A feed mechanism for use transferring linkless ammunition especially cased telescoped ammunition, from location to another, and simultaneously changing the orientation of its axis, comprising an Archimedes feed screw (11) and a cam track (14, 18, 17) located around the feed screw. Successive rounds (8) of ammunition are fed to the screw (11) so as to be received in the troughs of the screw thread. The cam track holds the rounds engaged within the troughs (15), while rotation of the screw advances the round along the cam track. The cam track is shaped so as to rotate the axis of successive rounds as they are advanced along its length to a discharge end.
