Abstract: For resizing an ammunition cartridge casing, an expandable and contractible collet is surrounded by an axially movable internally tapered sleeve. An axially movable headed shaft for supporting a cartridge casing from its flanged end is in the collet. Shifting the sleeve in one direction opens the collet and simultaneous retraction of the shaft lets the cartridge casing drop into the collet. Shifting the sleeve in the opposite direction causes the collet to contract and resize the cylindrical casing and its flange. Returning the sleeve to its initial position allows the collet to expand and simultaneous elevation of the shaft lifts the resized casing up to the top of a work table in position to be removed by hand or to be moved to a new work station for performance of other steps connected with cartridge reloading if the resizer is built into a reloading device.

Abstract: A crimping die which is movably mounted in one end of a shotgun shell crimping sleeve has a conically shaped side wall which permits the crimped end of the shell to overhang the crimping die to cause ironing of the crimped end of the shell against the rounded crimping corner of the crimping sleeve when the crimping die is withdrawn from the crimped shell.

Abstract: A primer tray is mounted on the tool carriage of a shotgun shell reloader and is tilted to urge the primers therein toward a dispenser opening in one corner of the tray. A dispenser arm moves one of the primers over the dispenser opening when the reloading tools on the tool carriage are moved to contact shotgun shells on the reloader's work table. A dispenser tube is attached to the bottom of the primer tray under the dispenser opening and guides the primer to a predetermined primer delivery point on the work table. In one embodiment, the primer dispenser tube is within the ram which seats the primer in the base of the shotgun shell. In another embodiment, the primer dispenser tube is adjacent to the primer seating ram.
