ABSTRACT:
Paintballs are loaded into a paintball gun. The paintballs are stored within a drive tube of a paintball loader. The paintballs are loaded into the paintball gun from the drive tube of the paintball loader. A screw is rotated with respect to the drive tube so that the paintballs are constrained to travel along a helical groove of the screw and along one of multiple column grooves on an inner surface of the drive tube.
