A projectile for use in a firearm ammunition cartridge, and a method of forming the projectile, the projectile including a core, and a jacket in which the core is disposed, the jacket having a closed rearward end and an open forward end, the forward end tapering inwardly toward a longitudinal centerline of the jacket to define an ogive portion of the projectile, wherein the forward end of the jacket terminates in a plane that is perpendicular to the longitudinal centerline of the jacket, and wherein an outer perimeter of the forward end of the jacket has a machined sharp edge.

A cartridge with a bullet has desirable penetration capabilities and controlled separation of components upon terminal impact. In embodiments of the invention, the bullet comprises a forward component, a lead core, and a copper jacket. The bullet having a forward nose portion with a plurality of cutaways spaced circumferentially about the nose portion. The copper jacket having a leading edge portion positioned at the cutaways.

A supercavitating cargo round comprises an energetic payload and an electronic payload. The electronic payload includes programmable circuitry suitable for implementing a digital delay of arbitrary length. The supercavitating cargo round is programmable while in a barrel or loader of a weapon.

This invention relates to a combination of a gun having a rifled barrel and a round of enhanced performance ammunition, and to a projectile for use in the combination. The invention is especially, but not exclusively related to a projectile with a nominal calibre, for use in a rifled barrel, the projectile comprising: an elongate metal core, a ceramic tip with a Vickers Hardness greater than said metal core, said ceramic tip abutted with one end of the elongate metal core, wherein a deformable jacket or deposited coating, surrounds the elongate metal core and ceramic tip, such that said jacket or coating defines the nominal calibre of said projectile.
