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.

Method of improving the accuracy of rifle ammunition
A method of supplying a rifle with cartridges includes providing classes within a group of cartridges. The classes are classified by specific and precisely graduated increments of propellant load contained in the cartridges, or by formulation of propellant, of each class relative to the cartridges of each other class. The user can test fire a rifle with multiple classes of the group and record the accuracy of the firing. A class of the group can be then chosen for a particular rifle based on accuracy of the rifle in the test firing.

Automatic apparatus for high speed precision portioning of granules by weight
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.
