ABSTRACT:
An ammunition powder measuring and dispensing apparatus in which a charging chamber rotates and translates in a helical course within a housing between inlet and outlet ports. The powder is gravity loaded and discharged from the chamber from a hopper above the inlet port and to a cartridge or shell below the outlet port. A micrometer-operated disc in the chamber adjusts the amount of the charge. The disc is concave to reduce crevices where powder can build up, and the chamber is tapered to small opening to improve cut-off leveling of powder at the inlet port.
