Abstract

The present invention provides a projectile device and a method of manufacture of a projectile device and in particular to a pistol bullet and a rifle bullet and method of manufacture of same. In one embodiment, the projectile apparatus has a cylindrical body portion having a diameter, a front nose section tapering from a most proximal point of the projectile to the cylindrical body portion, and a rear tail section connected to the body portion and extending to the most distal point of the projectile, in which the front nose portion comprises a plurality of twisting depressions forming troughs.

Claims

1. A projectile with enhanced performance characteristics for use with a firearm, comprising:

a housing comprising a front end, a rear end having a base, a cylindrical portion integrally interconnected to the base and extending to a nose portion, and a cavity extending from the front end, wherein the cylindrical portion comprises a plurality of angled driving bands and a plurality of angled relief cuts, wherein each angled driving band has a larger circumference than each angled relief cut, and wherein each angled driving band is positioned between two angled relief cuts; and

an insert comprising;

a first end having a tip;

a second end having a base;

a stem portion extending from the second end to a first point of the insert between the first end and the second end;

a nose portion tapering from the tip to the stem portion, wherein the nose portion is integrally interconnected to the stem portion at the first point of the insert;

a plurality of depressions cut into a surface of the insert and originating at a second point of the insert between the tip and the first point of the insert and terminating at a third point of the insert between the second point and the base, wherein each depression in the plurality of depressions has a curved shape with a radius of curvature, and wherein each depression has a centerline positioned at an angle relative to the longitudinal axis of the projectile; and

a plurality of remaining nose portions, wherein each remaining nose portion in the plurality of remaining nose portions is positioned between two of said depressions.

2. The projectile of claim 1, wherein the nose portion of the insert has a concave radius of curvature.

3. The projectile of claim 1, wherein the nose portion of the insert has a convex radius of curvature.

4. The projectile of claim 1, wherein a forward portion of the stem of the insert has a first diameter and a rear portion of the stem of the insert has a second diameter, and wherein the first diameter is larger than the second diameter.

5. The projectile of claim 1, wherein the base of the insert has an angled shape terminating in a point.

6. The bullet of claim 1, wherein each depression in the plurality of depressions has a curved shape with a specific radius of curvature, and wherein each depression has a centerline positioned at an angle relative to the longitudinal axis of the projectile.

7. A bullet adapted for insertion into a casing filled with an explosive propellant, comprising:

a front end having a rounded tip;

a rear end having a base;

a cylindrical portion integrally interconnected on a first end to the base and extending from a first point proximate the rear end to a second point between the front end and the first point, wherein the cylindrical portion comprises a plurality of angled driving bands and a plurality of angled relief cuts, wherein a highest point of each angled driving band in the plurality of angled driving bands has a larger diameter than a lowest point of each angled relief cut in the plurality of angled relief cuts, wherein each angled driving band is positioned between two angled relief cuts, and wherein angles between the angled driving bands and the angled relief cuts relative to a longitudinal axis of the bullet are between about 6 degrees and about 11 degrees;

a nose portion tapering from the tip to the cylindrical portion at the second point, wherein the nose portion is integrally interconnected to the cylindrical portion at the second point;

a cavity formed in a portion of the nose portion; and

an insert positioned at least partially within the cavity, and wherein the insert includes an apex at a first end opposite a base at a second end and a plurality of arcuate-shaped cutout portions originating a predetermined distance behind the apex and terminating at a third point in the cavity.

8. The bullet of claim 7, wherein the insert comprises a first nose portion at the first end and extending to a stem portion that extends to the base, the first nose portion having a first radius of curvature and the stem portion having a substantially linear outer surface, and wherein the first nose portion is positioned outside of the cavity and a forward portion of the stem portion is positioned outside of the cavity and a rear portion of the stem portion is positioned within the cavity.

9. The bullet of claim 8, wherein the plurality of arcuate-shaped cutout portions originate in the first nose portion and terminate in the stem portion.

10. The bullet of claim 9, wherein the plurality of arcuate-shaped cutout portions are cut into the first nose portion and the stem portion such that a diameter of the insert measured through at least one arcuate-shaped cutout portion in the plurality of arcuate-shaped cutout portions is smaller than a diameter of the insert.

11. The bullet of claim 8, wherein the nose portion of the bullet comprises the first nose portion of the insert and a second nose portion with a second radius of curvature.

12. The bullet of claim 8, wherein the insert further comprises a plurality of nose remaining portions, wherein each nose remaining portion in the plurality of nose remaining portions is positioned between two of the arcuate-shaped cutout portions in the plurality of arcuate-shaped cutout portions, and wherein the nose remaining portions have the first radius of curvature.

13. The bullet of claim 7, wherein a lowermost portion of each of the arcuate-shaped cutout portions is positioned at an angle of between 5 degrees and 45 degrees with respect to a longitudinal axis of the insert such that the arcuate-shaped cutout portions twist around the longitudinal axis of the insert.

14. The bullet of claim 7, wherein the base of the insert has an angled shape terminating in a point.

15. The bullet of claim 7, wherein the third point is a second predetermined distance in front of the base.
