The light-weight handheld less-lethal ballistic projectile launcher is configured as an “over / under” double barrel handheld device with a “break open” loading action. The launcher includes a barrel section pivotally connected to receiver section. The barrel section pivots between an open load / unload position and a closed firing position. The barrel section includes two metal barrel sleeves that are press fit into axial bores formed in the body of the barrel section.

A tracer cylinder for use with a shotgun shell to provide an aiming and training aid for shotgun shooting sports, which also can be used for military and police applications. The tracer cylinder, which contains a liquid, is positioned in a shotgun shell above a disk-shaped piercing valve. The shell is loaded into a shotgun and fired. The forces of ignition cause the point on the piercing valve to puncture the bottom of the cylinder, and, when the cylinder is airborne, tracer liquid is released through the resulting opening by physical forces, creating a long-lasting mist or fog cloud that is visible to the shooter. The shooter is provided with a consistent and durable reference, allowing him or her to make effective corrections to his or her shooting technique. The tracer cylinder can be loaded into a shot holder, with or without shot pellets.

A deployable fairing is driven off of high-pressure gun gases to reduce aerodynamic drag and extend the range of the artillery shell. An artillery shell is provided with a fabric fairing and a piston attached thereto in a rear section of the shell in a stowed state and a chamber. During launch high-pressure gun gasses are captured and stored in the chamber. Once the shell clears the end of the artillery tube, the pressure aft of the shell drops from the high pressure inside the tube to atmospheric pressure outside the tube. The high pressure gun gasses stored in the chamber act over the top surface of the piston to drive the piston aft against the much lower pressure behind the projectile to deploy the fabric fairing attached thereto to reduce the base area of the projectile creating or extending the boat-tail of the shell, hence reduce aerodynamic drag. The aft driven piston engages a locking mechanism that locks the piston in a deployed position.

Positioned in the second compartment proximate to the frangible barrier is a fill port member that is movable in response to an applied force for rupturing the frangible barrier. The fill port member also has a fluid passageway for use in transferring an amount of the electrolyte to the second compartment. The dual purpose of the fill port member is that it efficiently uses the available space and permits the design and production of a more compact reserve battery for use in space-limited applications, such as artillery shells.

A method for the dispersion of projectiles from guns capable of firing multiple projectiles in rapid succession whereby some of the projectiles are modified by moving the center of mass of the projectile away from it's central axis and oriented prior to firing. This, in combination with bring fired from a rifled gun barrel, imparts velocity to the projectile upon exiting the gun barrel at right angles to the barrel. This velocity along with the higher muzzle velocity will cause the modified projectile to diverge away from the trajectory of a standard projectile. The magnitude of the divergence will vary with the distance the projectile's center of mass is away from its central axis, and the placement of the modified projectile strikes around the bull's-eye will be determined by the loading orientation of the modified projectile. Firing a multiplicity of standard and modified projectiles in rapid succession will produce an accurate dispersion pattern on a target, increasing the hit probability on that target.
