Abstract: A casing feeder device which attaches to and is adapted for use with a shell reloading machine. A casing hopper is mounted on the top of an upright loading tube and has a discharge opening through which casings fall by gravity rim end downwardly to the receiver portion of the reloading machine. An adjustable tube support collar loosely surrounds and supports the loading tube in an upright position, and is attached to a reciprocating link on the reloading machine to provide agitation to the hopper as the link is moved, causing migration of casings within the hopper to the discharge opening.
