The present invention provides a method of making a metal injection molded ammunition cartridge comprising the steps of: providing an ammunition cartridge mold comprising a bottom portion having a primer recess extending into the bottom portion adapted to receive a primer, a flash hole positioned in the primer recess through the bottom surface; side walls extending from the bottom portion to a nose end aperture, wherein a propellant chamber is formed between the nose end aperture and the bottom surface; injecting a metal composition into the ammunition cartridge mold to form a metal injection molded ammunition cartridge; and removing the metal injection molded ammunition cartridge from the ammunition cartridge mold.

A fin-stabilized sub-caliber projectile adapted to be fired from a rifled barrel, the projectile having a penetrator with a tail fin assembly, a sabot arranged on the penetrator and having at least two sabot segments circumferentially joined to one another that are separated from one another after leaving the barrel by centrifugal forces acting on the projectile during firing. The sabot includes a main body and a front guide flange that is adapted to be supported on an inner wall of the barrel and a rear guide flange arranged at an axial distance. A connecting section of the sabot is arranged between the front guide flange and the rear guide flange and has a smaller outer diameter than the front guide flange or the rear guide flange. The sabot and the penetrator are joined together in a positive manner in a region of the rear guide flange.

A sabot in which bionic structures are provided. The structures are generated or created by way of an additive manufacturing process during the manufacture of the sabot in a defined manner with respect to size, shape and/or volume and in a targeted manner with respect to the local and quantitative embedding in the sabot.

An aeromechanically stable sabot system that includes a center of gravity that is placed forward of an aerodynamic center of the aeromechanically stable sabot system when in steady-state flight. By placing the center of gravity forwards of the aerodynamic center, the sabot system exhibits positive longitudinal and directional stability. To illustrate, the sabot system and/or portions thereof will return to stable flight after being disturbed in pitch (vertically or about a transverse horizontal axis) or yaw (side to side or about a vertical axis) when traveling horizontally.

Gun and ammunition solutions which permit the use of High Explosive (HE) rounds and Armor Piercing Fin Stabilized Discarding Sabot (APFSDS) rounds in one weapon. A first system has a gun barrel chamber sized to receive the outer cases of both APFSDS and HE rounds. The chamber has a smooth rear section which abuts a front section having internal helical rifling. A HE round has an outer case with a length that is the same as the length of the smooth rear section of the barrel. A projectile held by the case has a rotating band on a rear end configured to engage the internal helical rifling in the chamber. A second system has a conventional smooth barrel and utilizes a HE round with an outer case having internal rifling in a forward section. A projectile held by the outer case has a circular band mounted to rotate about a rear end thereof to engage the internal rifling.

The invention relates to a cartridge having a projectile secured to a case that contains a propelling charge and closed by a base. A device for igniting the propelling charge has at least two energetic igniter cords that extend between an initiating means secured to a rear part of the case and the projectile. In this cartridge, the cords are joined at their rear part so as to form a strand, and they are fastened by at least one fastening means secured to the cartridge, the strand being connected to the initiating means by a packing gland making it possible to immobilize the cords both radially and axially relative to the initiating means while keeping the cords tight between their fastening means and the initiating means.

The present invention provides a metal injection molded ammunition cartridge comprising a metal injection molded bottom portion comprising a primer recess in communication with a primer flash hole that extends into a propellant chamber and a metal injection molded body extending form the metal injection molded bottom portion.
