Abstract

A cartridge with component bullet has desirable penetration capabilities and controlled separation of components upon terminal impact. In embodiments of the invention, the cartridge comprises a component, a lead core, and a copper jacket. The lead jacket having a leading edge portion that exposes the cutaways. The component bullet may have a forward pointed ogive portion with cutaways spaced circumferentially.

Claims

1. A pistol cartridge comprising a cartridge casing with open mouth and an interior, propellant in the interior of the cartridge casing, and a bullet secured in the mouth of the cartridge casing, the bullet comprising:

a forward component, the forward component having forward ogive portion with a forward tip, a plurality of circumferential spaced divots exposed on the ogive portion;

a core portion positioned rearwardly of the forward component; and

a jacket defining a cup, the forward component and core portion seated the cup, the jacket having a forward lip positioned such that the plurality of divots are forwardly exposed.

2. The pistol cartridge of claim 1 wherein the core comprises lead, the lead positioned rearwardly of the steel component in the cup and forming a lead core, the forward component in direct contact with the lead core.

3. The pistol cartridge of claim 2, wherein the jacket comprises copper and has a forward leading edge portion that engages the forward component.

4. The pistol cartridge of claim 3 wherein the leading edge portion and the cylindrical mid portion define a forward facing annular recess that facilitates opening of the jacket upon impact with a target.

5. The pistol cartridge of claim 2 wherein a rearward facing end surface of the forward component has structural features thereon that are reflected in a forward facing surface of the lead core inhibiting rotation of the forward component with respect to the lead core

6. The pistol cartridge of claim 1 wherein the forward component is comprised of steel.

7. A pistol cartridge comprising a cartridge casing with open mouth and an interior, propellant in the interior of the cartridge casing, and a bullet secured in the mouth of the cartridge casing, the bullet comprising:

a forward component a forward ogived portion with a forward tip, a cylindrical mid portion, and a tail portion, the ogived portion having cutouts spaced circumferentially around the ogive portion to open the jacket upon impact; and

a jacket formed of copper and defining a cup, the forward component seated in the cup, the jacket having a forward taper and a forward edge portion;

a lead core positioned rearwardly of the forward component in the cup.
