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.

A projectile for use in a handheld weapon, comprising:
- a front end having a tip;
- a rear end having a base and positioned opposite the front end;
- a longitudinal axis extending from the tip to the base;
- a boat tail portion extending from the rear end to a first point 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 an end diameter that is smaller than a first diameter at the first point;
- a cylindrical portion integrally interconnected on a first end to the boat tail portion at the first point, the cylindrical portion extending from the first point 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 each angled driving band in the plurality of angled driving bands is positioned between two angled relief cuts in the plurality of angled relief cuts, wherein each angled driving band in the plurality of angled driving bands has a rounded peak and a driving band diameter measured at a top of the rounded peak, wherein each angled relief cut in the plurality of angled relief cuts has a rounded valley having a radius of curvature and a relief cut diameter measured at a bottom of the rounded valley, and wherein each driving band diameter is larger than each relief cut diameter;
- and
- a nose portion tapering outward from the tip to the second point, wherein the nose portion is integrally interconnected to the cylindrical portion at the second point.
