Abstract
A powder dosing apparatus, especially for use in the priming of ammunition, comprises a tray containing a uniformly thick layer of powder and a dosing assembly arranged to extract a plurality of doses of powder from the tray. After extraction of the doses the assembly is moved to an adjacent station where it ejects the doses into respective receptacles, such as capshells. During ejection, the powder in the tray is replenished from a chute and the layer is raked and levelled by an assembly comprising a rake and doctor blades in readiness for a subsequent dose extraction step.
