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 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 comprising
a forward ogive portion with a forward tip,
a mid portion adjoining the forward ogive portion, and
a rearward portion adjoining the mid portion, the rearward portion comprising a rearward facing end surface, and

a jacket defining a cup, the forward component received within the cup, the jacket comprising
a leading edge positioned at the mid portion of the forward component, the leading edge comprising a reverse taper such that the leading edge is separated from the mid portion and has a greater diameter than the mid portion and forward ogive portion, and

a rearward facing concavity.

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

3. The pistol cartridge of claim 1 , the mid portion further comprising a profile selected from cylindrical, slight forward taper, and conical.

4. The pistol cartridge of claim 1 , comprising the forward component comprising the forward ogive portion of the forward component being contiguous, without any intermediate structure, with the mid portion, the mid portion being contiguous, without any intermediate structure, with the rearward portion.

5. The pistol cartridge of claim 1 , comprising the forward component comprising the entirety of the rearward portion diametrically larger than the mid portion, and the entirety of the mid portion diametrically larger than the forward ogive portion.

6. The pistol cartridge of claim 1 , the bullet further comprising a core, the core positioned rearwardly of the forward component, the forward component in direct contact with the core.

7. The pistol cartridge of claim 6 , the forward component comprising steel.

8. The pistol cartridge of claim 6 , the jacket comprising copper.

9. The pistol cartridge of claim 6 , the core comprising lead.

10. The pistol cartridge of claim 6 , the core comprising copper.

11. The pistol cartridge of claim 6 , the bullet comprising the core that is unitary with the jacket.

12. The pistol cartridge of claim 6 , the rearward facing end surface of the forward component comprising rotation inhibiting features thereon that interface with the core comprising an interface feature, inhibiting rotation of the forward component with respect to the core.

13. The pistol cartridge of claim 1 , the mid portion comprising a mid portion surface that adjoins a forward ogive portion surface of the forward ogive portion, the rearward portion further comprises a tapered surface adjoining the mid portion surface, and the rearward portion comprising a maximum diameter portion positioned at a unitary rearward portion of the rearward portion, the maximum diameter portion comprising a diameter greater than the diameter of the mid portion.

14. The pistol cartridge of claim 1 , the forward ogive portion comprising cutouts spaced circumferentially around the ogive portion to facilitate opening the jacket upon impact.

15. The pistol cartridge of claim 14 , the forward ogive portion comprising cutouts extending rearwardly of the forward ogive portion and radially inward from the leading edge of the jacket.

16. The pistol cartridge of claim 14 , the bullet comprising a forward facing scoop area at each of the cutouts defined by the jacket and the forward component.

17. The pistol cartridge of claim 14 , wherein each cutout extends the full axial length of the mid portion.

18. The pistol cartridge of claim 1 , the mid portion further comprising a profile selected from cylindrical, slight forward taper, and conical.

19. The pistol cartridge of claim 1 , the jacket further comprising skives on a forward portion of the jacket.
