The Bangerter powderless gun was an external driven machine gun capable of firing 10000rpm without propellant, pneumatics or even making a sound.
When the weapon was tested, it was kept out of sight in a cubicle in the corner of a room with half inch thick pine target boards 65 feet away. It fired 100 rounds a second and within 2 seconds, all 3 target boards were penetrated. It made no sound whatsoever other than the engine, loading of the BB's in the hopper and ricochets around the targets.
The Bangerter powderless gun was described by the inventor himself as extremely simple. It is a hopper fed weapon driven by a 7hp gas/electric driven engine although it is still unknown was the weapon looked like although portrayed in a newspaper article as a hopper fed, 4 barrel weapon mounted on a tripod.
