An automated granule portioning system includes at least one volumetric measuring chamber capable of adjusting the volume of the chamber automatically to a programmed target volume and arranged to receive a first portion of granules into the chamber to fill the target volume. A transport system automatically delivers the target volume of granules from the chamber to a weighing device. A granule metering device dispenses granules and, depending on a signal from the weighing device that the first portion of granules is below a programmed target weight, dispenses granules to the first portion to increase the weight to achieve a second portion having the target weight.

This invention relates to a material feeder system and method of use. The present invention relates particularly to a particulate feeder system that includes, among other features, one or more: feeder assemblies for advancing material that incorporate a spool having a channel disposed within its outer circumference for advancing material, the spool having a plurality of circumferentially spaced contours configured so as to not form transverse barriers within the channel; motors configured to connect to the feeder assemblies; and scales for weighing advanced material. The system also includes a computer in communication with the one or more motors and scales, and capable of performing operations to advance a predetermined material weight as well as various related operations. The invention also includes a method using the above.

A dispenser for dispensing powder for firearm ammunition and associated methods. The dispenser can include a hopper, a conveyor, a scale sensor, a dispensing head, a dispenser controller, and a tangible storage medium storing instructions executable by the dispenser controller. The dispensing head is movable to a plurality of dispensing positions to dispense ammunition powder to a plurality of cases from the plurality of dispensing positions. In some embodiments, the dispensing head moves between a home position, where the dispensing head receives powder from the conveyor, and the plurality of dispensing positions, where the dispensing head delivers loads of powder from the conveyor to individual ammunition cases.
