A separate-loading firearm uses a battery-powered electric resistance heating element to ignite a propellant charge. Both ignition reliability and ballistic reproducibility are enhanced when a first portion of the propellant charge is consistently and firmly packed into a cavity formed in a rear surface of a bullet. This first portion may be sealed in the cavity by a membrane. A second portion of the propellant charge is packed within a firing chamber so that it abuts both the heating element and the first portion of the propellant charge.

The present disclosure relates to an induction annealing apparatus adapted to anneal cartridge cases to improve their reusability. In one implementation, the apparatus includes a power supply unit and a plurality of annealing units, each including a magnetic core having ends separated by an air gap. An induction coil is wound around the magnetic core to generate a magnetic field in the air gap. A cartridge case holder holds the cartridge case such that the neck of the cartridge case is positioned in one of the air gaps. The power supply unit selectively connects to the annealing units to supply power for a predetermined length of time, and the size of the air gap of the magnetic cores of each of the annealing units may differ. In other implementations, the size of the air gap may be adjustable, and a temperature sensor or a ferrite stake may be included.

The invention relates to a system to increase the effectiveness of direct fire weapon systems in targeting and destroying a target utilizing the military's existing direct fire weapon systems. The invention consists of a network which communicates with the devices of the invention and that are capable of directing the fire to a specific location.

The invention relates to a disintegrating bullet that breaks apart at set distances in order to better engage targets such as unmanned aerial systems.

Disclosed is a cartridge case for various caliber ammunition that can consist essentially of a powdered metal and/or powdered metal alloy(s) that is formed into the cartridge case through an injection mold processing. Also disclosed is a method for forming a cartridge case, which may include use of Metal Injection Molding (MIM) processes to produce the cartridge case which retains a primer, propellant, and/or a bullet. Also disclosed are embodiments related to a case telescoped cartridge that may include a cap and a body. The body can consist essentially of or consists entirely of a powdered metal and/or powdered metal alloy(s) that has been formed through MIM. The cap can comprise plastic that has been formed through plastic molding or comprise powdered metal and/or powdered metal alloy(s) that has been formed through MIM.
