Disclosed is a cartridge case for various caliber ammunition that consists essentially of a powdered metal and/or powdered metal alloy 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. The method can include metal injection molding an initial part, and also at least one of tapering and trimming the initial part to form the finished cartridge case. Further embodiments can include the use of Finite Element Method (FEM) analysis to develop an optimized MIM design.

The present invention provides a method of making a subsonic ammunition having a polymeric casing body having a generally cylindrical hollow polymer body having a body base at a first end thereof and a mouth at a second end to define a propellant chamber; a propellant insert positioned in the propellant chamber to reduce the internal volume of the propellant chamber, wherein the propellant chamber has an internal volume that is at least 10% less than the open internal volume of a standard casing of equivalent caliber; and a primer insert positioned in the body base and in communication with the propellant chamber.

Ammunition for a conductive energy weapon. A receptacle includes a cavity accessible through each of a first opening in a first face of the receptacle, a second opening in the first face of the receptacle, a third opening in a second face of the receptacle and a fourth opening in a third face of the receptacle. A propellant unit is included within the cavity proximate the second opening and a projectile is included within the cavity proximate the second opening. A housing is coupled to at least the second face and the third face of the receptacle and is further configured to couple to the conductive energy weapon. The propellant unit releases a propellant into the cavity, in a direction substantially opposite the projectile's direction of flight, in response to a trigger pull of the conductive energy weapon, and the cavity directs the propellant in the projectile's direction of flight.

A firearm ammunition cartridge comprises a case having a substantially tubular body portion, an open leading end, and a trailing end defining a primer port. An insert is received within the case and extending along the body portion. The insert has an exterior surface conforming to an interior surface of the body portion and a central cavity extending along an axial dimension of the insert. The central cavity opens to the primer port at the trailing end of the case and to a leading end of the insert. A quantity of gunpowder is disposed within the central cavity, and a projectile is received and retained within the leading end of the case. The gunpowder is confined to a chamber comprising at least a portion of the central cavity between said case trailing end and the projectile.

A projectile includes a component that is highly reflective and configured to reveal the projectile's trajectory when the projectile is fired from a gun and electromagnetic radiation is directed toward the projectile. With the reflective component, one can more easily limit the visibility of the projectile to areas from where the projectile was fired because the reflective component is passive, not active. As the projectile moves down range, the areas behind the projectile are typically where a shooter and/or spotter for the shooter are located, not where an enemy combatant is located. Thus, the trajectory of the projectile is revealed to the people who can use the information to adjust their fire, and remains hidden from the people who could use the information to locate the shooter.
