Abstract

The disclosed ammunition is adapted for flowering into a plurality of sections upon impact with a body or object. The ammunition comprises a cylindrical casing, a charge disposed within the cylindrical casing and cylindrical projectile, defining a first portion within the casing and a second portion extending from the casing. The projectile comprises a projectile body and projectile jacket. The projectile jacket is disposed about at least a portion of the projectile body. The projectile body and/or the projectile jacket each define a leading end and a plurality of radially arrayed score lines formed therein, extending from the leading end. Upon impact, the projectile body and/or the projectile jacket flower into a plurality of radially arrayed sections, the sections being defined by the score lines formed in the projectile body and/or the projectile jacket.

Claims

1. Ammunition adapted for flowering into a plurality of sections upon impact with a body or object, the ammunition comprising:

a charge disposed within the cylindrical casing; and

a cylindrical projectile defining a first portion disposed within the casing and a second portion extending from the casing, the projectile comprising a projectile body and projectile jacket, the projectile jacket being disposed about at least a portion of the projectile body;

the projectile body defining a projectile body leading end, the projectile body leading end defining a circumference, the projectile body defining a hollow core extending longitudinally from the circumference toward an opposite end of the projectile body, the hollow core having a closed end, the closed end defining a circumference, and the projectile body defining a plurality of radially arrayed score lines formed in the projectile body, the plurality of the radially arrayed score lines extending along a portion of the projectile body from the projectile body leading end;

the projectile jacket comprising an exterior surface portion defined by a plurality of radially arrayed score lines, the plurality of radially arrayed score lines extending from a circumference of a projectile jacket opening longitudinally toward a base of the cylindrical projectile, along the projectile jacket exterior surface, to a circumference on a perimeter of the projectile jacket exterior surface proximal of a projectile jacket leading edge, the exterior surface portion defining a convex surface, and the plurality of radially arrayed score lines extending through the projectile jacket to the projectile body;

wherein the projectile jacket opening defines a projectile jacket leading edge, the circumference on a perimeter defines a common base of the sections, and the circumference of the projectile jacket opening, the circumference of the leading end of the projectile body, and the circumference of the closed end are equal;

wherein upon impact, the projectile body and the projectile jacket each flower in sections, connected only by the common base of the sections, radially outward into a plurality of radially arrayed sections, the sections being defined by the score lines formed in the projectile body and the projectile jacket.

2. The Ammunition of claim 1, further comprising a prong having a first end on a first portion disposed within the cylindrical hollow core, and a second portion extending outwardly therefrom, and wherein upon impact the prong is urged into the projectile, facilitating flowering of the projectile body and the projectile jacket into the plurality of sections;

wherein the first end of the prong is in contact with the closed end of the cylindrical hollow core.

3. The Ammunition of claim 2, wherein the projectile jacket is not attached to the prong.

4. The Ammunition of claim 1, further comprising a cylindrical prong within the hollow core, the cylindrical prong in contact with the closed end.

5. The ammunition of claim 1, wherein the projectile jacket opening defines a diameter, the leading end of the projectile body defines a diameter, and the closed end defines a diameter, and the diameter of the projectile jacket, the leading end of the projectile body, and the closed are all equal.

6. Ammunition adapted for flowering into a plurality of sections upon impact with a body or object, the ammunition comprising:

a prong;

a casing;

a projectile disposed at least in part in the casing, the projectile comprising a projectile body and projectile jacket, the projectile jacket being disposed about at least a portion of the projectile body;

the projectile body defining a hollow core extending longitudinally from a projectile body opening, the projectile body opening defining a projectile body leading end, toward an opposite end of the projectile body, and the hollow core having a closed end opposite the projectile body opening, and the projectile body defining a plurality of radially arrayed score lines formed in the projectile body, the plurality of radially arrayed score lines extending along a portion of the projectile body from the projectile body leading end;

the projectile jacket comprising an exterior surface portion including a plurality of radially arrayed score lines, the plurality of radially arrayed score lines extending from a projectile jacket opening, longitudinally toward a base of the cylindrical projectile, to a circumference on a perimeter of the projectile jacket exterior surface proximal of the projectile jacket opening, the plurality of radially arrayed score lines extending through the projectile jacket to the projectile body, and the projectile jacket opening defining a projectile leading edge;

wherein the circumference on a perimeter defines a common base of the sections, and wherein the prong is in abutting contact with the projectile jacket opening, the projectile body opening, and the closed end;

wherein upon impact, the projectile body and the projectile jacket each flower in sections, connected only by the common base of the sections, radially outward into a plurality of radially arrayed sections, the sections being defined by the score lines formed in the projectile body and the projectile jacket.

7. The ammunition of claim 6, wherein the prong extends distally and proximally from the projectile jacket opening.

8. The ammunition of claim 6, wherein the hollow core defines a length and a circumference, and the circumference is constant for the entire length.

9. The ammunition of claim 6, wherein the prong is cylindrical and defines a diameter, and the projectile jacket opening defines a diameter, the projectile body hollow core defines a diameter, and wherein the prong diameter, the projectile jacket opening diameter, and the projectile body hollow core diameter are substantially equal.

10. Ammunition adapted for flowering into a plurality of sections upon impact with a body or object, the ammunition comprising:

a cylindrical casing;

a charge disposed within the cylindrical casing; and

a cylindrical projectile defining a first portion disposed within the casing and a second portion extending from the casing, the projectile comprising a projectile body and projectile jacket, the projectile jacket being disposed about at least a portion of the projectile body;

the projectile body defining a hollow core extending longitudinally from an opening defining a leading end of the projectile body toward an opposite end of the projectile body, and the hollow core having a closed end opposite the opening defining the leading end of the projectile body, and the projectile body defining a plurality of radially arrayed score lines formed in the projectile body, the plurality of radially arrayed score lines extending along a portion of the projectile body from the projectile body leading end;

the projectile jacket comprising an exterior surface portion including a plurality of radially arrayed score lines, the plurality of radially arrayed score lines extending from a projectile jacket opening, longitudinally toward a base of the cylindrical projectile, to a circumference on a perimeter of the projectile jacket exterior surface proximal of a projectile jacket leading edge, the plurality of radially arrayed score lines extending through the projectile jacket to the projectile body, and the projectile jacket leading edge defining a projectile leading edge;
