Abstract

A bullet for a firearm includes a rear unit that comprises substantially a solid structure. Additionally, the bullet includes a front unit separate and discrete from the rear unit. The front unit defines a cavity and at least a portion of the rear unit is secured in the cavity of the front unit.

Claims

1. A bullet for a firearm comprising:

a rear unit comprising a substantially solid structure; and

a front unit separate and discrete from the rear unit, the front unit defining a cavity, at least a portion of the rear unit is secured in the cavity of the front unit.

2. The bullet of claim 1, wherein at least one of the rear and front units has an outer peripheral configuration dimensioned to be slidingly secured in a barrel of a firearm.

3. The bullet of claim 1, wherein both of the rear and front units have an outer peripheral configuration dimensioned to be slidingly secured in a barrel of a firearm.

4. The bullet of claim 1, wherein the front unit comprises a substantially hollow configuration of material.

5. The bullet of claim 1, wherein the front unit defines an opening extending from an end of the front unit and providing fluid communication with the cavity.

6. The bullet of claim 1, wherein the front unit defines a plurality of slots extending radially from the cavity and circumferentially-spaced around a periphery of the front unit.

7. The bullet of claim 1, wherein the front unit defines a plurality of slots extending radially from the cavity and circumferentially-spaced equally around a periphery of the front unit.

8. The bullet of claim 1, wherein the front unit defines a plurality of slots extending axially from a first end toward an opposite second end of the front unit.

9. The bullet of claim 8, wherein the plurality of the slots comprises four slots.

10. A cartridge for a firearm comprising:

a solid structure comprising a rear portion and a front portion extending from the rear portion;

a hollow structure defining a bore in fluid communication with a cavity, the cavity being defined at one end of the hollow structure, at least a segment of the front portion of the solid structure is secured in the cavity of the hollow structure;

a casing comprising propellant and having an open end, the rear portion of the solid structure is secured in the open end; and

a primer configured in igniting relationship with the propellant.

11. The cartridge of claim 10, wherein the front portion of the solid structure comprises a first diameter dimension and the rear portion comprises a second diameter dimension that is greater than the first diameter dimension.

12. The cartridge of claim 10, wherein the hollow structure comprises an outer periphery having an ogival configuration.

13. A method of forming a bullet for a firearm, the method comprising:

forming an ogival unit defining an opening at one end;

forming a solid unit, the solid unit being separate and discrete from the ogival unit; and

securing at least a portion of the solid unit in the opening of the ogival unit.

14. The method of claim 13, wherein the forming of the ogival unit occurs before the forming of the solid unit.

15. The method of claim 13, wherein the forming of the ogival unit occurs after the forming of the solid unit.

16. The method of claim 13, wherein the forming of the ogival unit occurs substantially simultaneously with the forming of the solid unit.

17. The method of claim 13, wherein the forming of the ogival unit comprises configuring the ogival unit to separate into a plurality of separate fragments upon impact with a substrate.

18. The method of claim 17, wherein the plurality of the separate fragments comprises at least three fragments.

19. The method of claim 13, wherein the forming of the solid unit comprises configuring the solid unit to remain intact upon impact with a substrate.

20. The method of claim 13, wherein the forming of the solid unit comprises forming the solid unit to have an aerodynamic configuration, wherein the solid unit comprises substantially the same aerodynamic configuration upon impact with a substrate.
