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 having a forward-most portion, the forward-most portion comprising a point configuration;

a front unit separate and discrete from the rear unit, the front unit defining a cavity, at least a portion of the rear unit comprising the point configuration is secured in the cavity of the front unit; and

wherein the front unit defines a plurality of slots extending radially from the cavity and circumferentially-spaced around a periphery of the front unit, the plurality of slots extending from the cavity through an entirety of the front unit to the exterior of the bullet.

2. The bullet of claim 1, wherein the front unit defines an opening extending through an entire length of the front unit, a portion of the opening defined by the cavity.

3. 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.

4. The bullet of claim 1, wherein the rear unit comprises at least three portions, the at least three portions comprising:

a first portion comprising a conical configuration wherein the terminus of the conical configuration comprises the point configuration;

a second portion extending from the first portion, the second portion comprising a cylindrical configuration having a first diametric dimension; and

a third portion extending from the second portion, the third portion comprising a cylindrical configuration having a second diametric dimension different from the first diametric dimension of the second portion.

5. The bullet of claim 4, wherein the first diametric dimension is less than the second diametric dimension.

6. The bullet of claim 1, wherein the cavity is configured as a cylindrical opening.

7. The bullet of claim 1, wherein the cavity is configured as a first cylindrical opening and a second cylindrical opening, the first cylindrical opening having a first diametric dimension and the second cylindrical opening having a second diametric dimension, wherein the first diametric dimension is greater than the second diametric dimension.

8. The bullet of claim 7, wherein the cavity is further configured with a tapered portion extending between the first and second cylindrical openings.

9. The bullet of claim 1, wherein the plurality of the slots is devoid of material.
