Abstract

A plated hollow-point bullet has a metallic plating which completely encapsulates a metallic core. A core precursor is formed having a nose compartment with an inwardly extending cavity. A metallic coating is applied to the precursor to completely encapsulate the precursor. The coated precursor is mechanically deformed by grooves formed along a surface of the cavity without breaching the coating.

Claims (17)

1. A bullet comprising:

a metal-containing core, having an aft end and a sidewall extending forward therefrom to a nose, said nose having a cavity extending therein;

a metallic plating having an inner surface contacting said core and an opposing outer surface, said metallic plating completely encapsulating the core including an entire surface of the core that defines an interior of said cavity, and including encapsulating the entire interior of said cavity; and

a plurality of grooves formed in said outer surface within said interior of said cavity that do not rupture said metallic plating,

wherein said plurality of grooves extend at least one half the length of said cavity.

2. The bullet of claim 1 wherein the metallic plating, along at least a majority of the surface of the core, has a thickness of at least 0.004 inch.

3. The bullet of claim 2 wherein said thickness along said majority is 0.0045 inch-0.010 inch.

4. The bullet of claim 2 having a maximum diameter between 0.35 and 0.46 inch.

5. The bullet of claim 4 wherein a ratio of said overall length to said maximum diameter is 1.5-2.5.

6. The bullet of claim 5 wherein said plating completely encapsulating the core is an electroplating.

7. The bullet of claim 5 wherein said plating completely encapsulating the core is a mechanical plating.

8. The bullet of claim 2 wherein said plating completely encapsulating the core is copper-based.

9. The bullet of claim 2 wherein a flash of copper is deposited between a nickel plating and said core.

10. The bullet of claim 2 in combination with:

a case selected from the group consisting of .357 Magnum, .357 Sig, .38 Special, .40 Smith & Wesson, .44 Magnum, .45 Automatic, 9 mm Luger and 10 mm Automatic, the bullet being accommodated by a mouth of the case;
