ABSTRACT:
This weapon has an axially moveable bolt which is removed from the path of an incoming cartridge so that the cartridge can be moved from its feed position directly along the axis of the bore into the gun chamber. After the bolt "disappears" from the path of the incoming ammunition, it then reappears behind the cartridge to move it along the barrel axis. This chambers the cartridge without the need for ramping since the cartridge is already aligned with the bore chamber
