Abstract

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.

First claim

What is claimed is:

1. A pistol cartridge, comprising:
a cartridge casing with an 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 core component positioned rearwardly of the forward component, and
a jacket defining a cup, the forward component received within the cup and the core component seated in the cup, the jacket having a leading edge portion at an adjacent portion of the forward component, the leading edge portion comprising a reverse taper such that the leading edge portion is separated from the adjacent portion of the forward component.

2. The pistol cartridge of claim 1 , further comprising a V-shaped recess formed by the leading edge and the forward component and defining a circumferential scoop.

3. The pistol cartridge of claim 1 , the bullet comprising a rearward facing concavity.

4. The pistol cartridge of claim 1 , the forward component in direct contact with the core component.

5. The pistol cartridge of claim 1 , the forward component comprising a mid portion adjoining a forward nose portion, and a rearward portion adjoining the mid portion, wherein the leading edge portion of the jacket terminates at the mid portion.

6. The pistol cartridge of claim 5 , the forward nose portion being ogival.

7. The pistol cartridge of claim 5 , the forward nose portion comprising cutouts spaced circumferentially around the ogive portion to facilitate opening the jacket upon impact.

8. The pistol cartridge of claim 5 , the mid portion further comprising a profile selected from cylindrical, slight forward taper, and conical.

9. The pistol cartridge of claim 1 , the jacket comprising copper.

10. The pistol cartridge of claim 1 , the core being unitary with the jacket.

11. 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 jacket formed of copper and defining a cup, the forward component received in the cup, the jacket having a forward edge portion comprising a reverse taper such that the leading edge portion is separated from the adjacent forward nose portion; and
a rearward facing concavity.

12. The pistol cartridge of claim 11 , further comprising a V-shaped recess formed by the leading edge and the forward component and defining a circumferential scoop.

13. The pistol cartridge of claim 11 , the bullet further comprising a core, the core positioned rearwardly of the forward component, the forward component in direct contact with the core.

14. The pistol cartridge of claim 11 , the forward component comprising a mid portion adjoining a forward nose portion, and a rearward portion adjoining the mid portion, wherein the leading edge portion of the jacket terminates at the mid portion.

15. 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 comprising a forward nose portion and a cylindrical portion directly rearward of the forward nose portion;
a jacket comprising copper and defining a cup, the jacket having a leading edge portion, the leading edge portion comprising a reverse taper such that the leading edge portion is separated from the adjacent cylindrical portion; and
a core in the cup of the jacket.

16. The pistol cartridge of claim 15 , further comprising a V-shaped recess formed by the leading edge and the forward component and defining a circumferential scoop.

17. The pistol cartridge of claim 15 , the bullet comprising a rearward facing concavity.

18. The pistol cartridge of claim 15 , wherein the cylindrical portion is a mid portion and the forward component further comprises a rearward portion comprising a tapered surface.
