1. A powder compaction device, comprising:
a drive motor operably connected to a compaction rod, the compaction rod being movable through a loading platform to a cartridge holding platform;
a powder loading station configured to hold a predetermined volume of propellant powder and positioned below the loading platform and above the cartridge holding platform, wherein the compaction rod is movable through the powder loading station and configured to receive the predetermined volume of propellant powder into one or more reliefs defined in the compaction rod as the compaction rod moves through the powder loading station to the cartridge holding platform;
the cartridge holding platform removably holding a cartridge fixture having a hollow interior chamber configured to receive an ammunition cartridge and a funnel defined at an upper portion of the cartridge fixture, the funnel opening into the hollow interior chamber;
wherein the one or more reliefs releases the loaded propellant powder into the funnel to be funneled into the hollow interior chamber after the compaction rod passes through the powder loading station; and
