A medium caliber high kinetic energy round with tracer and self-destruct mechanism having an optimized kinetic energy projectile incorporating a fully hardened projectile body and an explosive self-destruct mechanism for a medium caliber high rate of fire round. The medium caliber high kinetic energy ammunition round incorporates a multiple piece sub-projectile that integrates a tracer and high explosive self-destruct mechanism to neutralize the penetrator during self-destruct and minimize collateral damage during firing.

A fragmentation projectile in one aspect has a frontal cavity and defined fragments of medium to high density. The fragments are nearly form fitting together to form a compact projectile until its impact on the target. To achieve these specific mechanical properties, Additive Manufacturing (AM) methods are applied.

In making frangible objects, including lead-free bullets and other projectiles, powdered metal primary and powdered ceramic secondary phases are mixed and densified at an elevated temperature such that the ceramic phase forms a brittle network. Different combinations of metal and ceramic phases may be used to achieve desired chemical and physical properties. Any appropriate mixing, forming, and/or thermal processing methods and equipment may be used. Degrees of frangibility, strength, and toughness can be adjusted to suit a given application by precursor selection, degree of mixing, relative amounts of metal and ceramic phases, forming method, and thermal and mechanical processing parameters.

A projectile may be formed having a caliber in the range from 4.6 mm to 20 mm for ammunition. The projectile may be a deformation bullet, a partial fragmentation bullet, a partial or full jacket bullet, a hard-core bullet or tracer bullet. The projectile may be formed by cold forming, in particular extrusion, from an intermediate with a tube section of substantially constant wall thickness, which constitutes at least 50% of the longitudinal extension of the intermediate.

In one aspect, the invention relates to compositions useful in frangible projectiles, methods of making same, and articles comprising same This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present invention.

A cartridge incorporating a projectile assembly, the projectile assembly having a base, mid body component housing a marking powder and lighter metallic nose cap. The projectile's mid-body component undergoes wall failure at impact, the wall failure is induced as forward momentum of the base and other residual forces act to expel the marking powder from the projectile, the manner of ejection suspending a low density material with contrast dye, in the vicinity of the impact, providing a gunner with visual cue in regard to a projectile's impact location.

A small arms ammunition round comprises a non-brass casing comprising stainless steel and a non-lead projectile housed within the casing, the non-lead projectile comprising a matrix of at least one epoxy, at least one non-epoxy polymer, and copper. The casing includes a stainless steel shell housing and an aluminum primer housing which are press-fit together. The projectile has a tapered nose with spiral flutes.
