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 for use in a handheld weapon, comprising:

a cylindrical body with a longitudinal axis, a first end substantially perpendicular to said longitudinal axis, a second end, and a first length extending from said first end to said second end;

a nose integrally interconnected at a junction to said second end of said cylindrical body, said nose having a tip on a forward-most portion and a second length between said tip and said junction, wherein said second length is longer than said first length, said nose further comprising;

(a) a plurality of cutout portions originating at said tip of said nose and terminating proximate said junction, wherein each cutout portion in said plurality of cutout portions forms a curved trough with a radius of curvature, and wherein a lowermost portion of each of said troughs is positioned at a predetermined angle with respect to said longitudinal axis of said cylindrical body;

(b) a plurality of non-distorted nose portions, wherein each non-distorted nose portion is positioned between two of said cutout portions, and wherein said plurality of non-distorted nose portions extends to said tip of said nose portion; and

(c) wherein said tip of said nose portion is substantially parallel to said first end of said cylindrical body.

2. The projectile of claim 1, wherein each non-distorted nose portion has a substantially triangular shape with a narrow portion of said substantially triangular shape proximate said tip and a wide portion of said substantially triangular shape proximate said junction.

3. The projectile of claim 1, wherein each cutout portion in said plurality of cutout portions has a third length as measured along said longitudinal axis that is slightly less than or equal to said second length.

4. The projectile of claim 1, wherein each cutout portion in said plurality of cutout portions has a radius of curvature of between about 0.05 inches and about 0.25 inches.

5. The projectile of claim 1, further comprising a chamfer portion extending from said first end of said cylindrical body to a point on said cylindrical body, wherein said chamfer is positioned at an angle relative to said longitudinal axis.

6. The projectile of claim 1, wherein said cutout portions have either a right twist or a left twist with respect to said longitudinal axis of said projectile.

7. The projectile of claim 1, wherein said plurality of cutout portions comprises three cutout portions and said plurality of non-distorted nose portions comprises three non-distorted nose portions.

9. The projectile of claim 1, wherein said first length of said cylindrical body is between about 0.11 and 0.285 inches and said second length of said nose is between about 0.20 and 0.45 inches.

10. The projectile of claim 1, wherein each cutout portion in said plurality of cutout portions is oriented at an angle of between about 5 degrees and 15 degrees with respect to said longitudinal axis of said cylindrical body.

11. The projectile of claim 1, wherein said projectile is sized in at least one of a 0.380 inch, a 9 mm, a 0.40 inch, and a 0.45 inch caliber and is adapted for use with a handgun.

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

a longitudinal axis;

a housing comprising;

a front end;

a rear end having a base, the rear end positioned opposite the front end;

a boat tail portion extending from the rear end to a first point of the housing between the front end and the rear end, wherein the boat tail portion tapers inwardly toward the longitudinal axis such that the rear end has a smaller diameter than a diameter at the first point of the housing;

a cylindrical portion integrally interconnected on a first end to the boat tail portion at the first point of the housing, the cylindrical portion extending from the first point of the housing to a second point of the housing between the front end and the rear end;

a nose portion tapering from the front end to the cylindrical portion at the second point of the housing, wherein the nose portion is integrally interconnected to the cylindrical portion at the second point of the housing; and

a cavity for receiving an insert, the cavity extending from the front end to a third point of the housing between the front end and the rear end; and

the insert comprising;

a first end having a tip;

a second end having a base, the second end positioned opposite the first end;

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 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.

13. The projectile of claim 12, wherein the nose portion of the insert has a concave radius of curvature.

14. The projectile of claim 12, wherein the nose portion of the insert has a convex radius of curvature.

15. The projectile of claim 12, 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.

16. The projectile of claim 12, wherein the base of the insert has an angled shape terminating in a point.

17. The projectile of claim 12, wherein the cylindrical portion of the housing comprises a plurality of angled driving bands and a plurality of angled relief cuts, wherein each angled driving band in the plurality of angled driving bands has a larger diameter than each angled relief cut in the plurality of angled relief cuts, and wherein each angled driving band is positioned between two angled relief cuts.

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