Abstract: A method and apparatus for drilling and penetrating hard materials utilizes a high velocity gun system that fires multiple shots of a projectile and an energetic slurry at the surface of the material to be penetrated. The penetrating device includes one or more firing barrels that are loaded with a propellant, a projectile and an energetic (explosive) slurry, and are controlled to fire in a preselected firing sequence. The projectile enters the material to be penetrated generating a hole into which the energetic slurry is also fired. The energetic slurry detonates upon contact with the material causing an explosion that further fractures the material and which blows the material out of the hole. The process is repeated until a desired penetration depth is obtained.

Abstract: A disc for use in the manufacture of gun ammunition and a round of gun ammunition which includes the disc. A preferred disc comprises a mixture of metal powders compressed into self-supporting deformable disc that is incorporated along with a core into a jacket to define the projectile of a round of gun ammunition. The disc is frangible upon the projectile striking a solid or semi-solid target. Preferably the core is likewise frangible. In one embodiment the disc is incorporated into the ogive of a projectile. In another embodiment, a disc may be incorporated into a projectile comprising multiple cores, the disc being disposed between adjacent surfaces of the cores. This latter disc commonly is in addition to the disc which is incorporated into the ogive of the projectile. A round of gun ammunition incorporating a powder-based disc in the projectile thereof is disclosed.

The high energy material is configured as a shaped charge and surrounds the ordnance housing of a rocket motor. During cook-off of the munition, the high energy material detonates, rupturing the structural integrity of the ordnance housing sufficiently to release pressure therefrom.

Abstract: A projectile for small arms, incorporating a core, skirt, and driving band. The present invention's design acts to increase muzzle velocity in three main ways. The core is lightweight, therefore, the same amount of propellent will cause the present invention to be pushed out of the barrel at a higher rate than a conventional heavier bullet. Additionally, a thin skirt circumscribing the base of the projectile is incorporated into it during manufacture. All of the design characteristics of the present invention act to increase the muzzle velocity of the projectile when used with a conventional load as compared to the same load used with a conventional projectile. The increased velocity is achieved in standard small arms without modification to barrels, recoil springs, or other devices. Law enforcement officers must be extremely careful in regard to innocent bystanders who may potentially be hit be an errant bullet, or by a bullet that over-penetrates its target.
