Abstract

A cartridge bullet having a truncated conical nose with radial rearwardly extending ribs with grooves defining curved surfaces between the ribs.

Claims

1. A small arms projectile, comprising:

(a) a substantially cylindrical main body;

(b) a front portion formed as one-piece with the main body and terminating in a flat front end which is smaller than the diameter of the main body;

(c) the front portion formed of a plurality of narrow ribs with parallel sides extending along their entire length, said ribs also extending radially outward and equally spaced around the front portion, the ribs extending from the main body to the flat front end, at least a major portion of the outer surface of the ribs continuously tapering from the outer diameter of the main body to the flat end; and

(d) cavities formed between the ribs, at least a major portion of which form a continuously curved surface from the outer diameter of the main body inwardly toward the flat front end.

2. The small arms projectile of claim 1, wherein the plurality of ribs include six ribs equally spaced around the outer surface of the front portion.

3. The small arms projectile of claim 1, and further including the ribs extending a short distance along the diameter of the main body and then tapering linearly to the flat end.

4. The small arms projectile of claim 1, wherein the curved surface of the cavities is in the shape of a parabolic curve.

5. The small arms projectile of claim 1, wherein the curved surface of the cavities is in the shape of an elliptical curve.

6. The small arms projectile of claim 1, and further including cap means in the cavities for filling the spaces between adjacent ribs and forming a smooth outer surface on the front portion.

7. A small arms cartridge, comprising:

(a) a small arms projectile including;

(1) a substantially cylindrical main body;

(2) a front portion formed as one-piece with the main body and terminating in a flat front end which is smaller than the diameter of the main body;

(3) the front portion formed of a plurality of narrow ribs with parallel sides extending along their entire length, said ribs also extending radially outward and equally spaced around the front portion, the ribs extending from the main body to the flat front end, at least a major portion of the outer surface of the ribs continuously tapering from the outer diameter of the main body to the flat end;

(4) cavities formed between the ribs, at least a major portion of which form a continuously curved surface from the outer diameter of the main body inwardly toward the flat front end; and

(b) a cartridge case for holding the main body, with a minor portion of the main body and front portion projecting out of the cartridge case.
