1. A projectile for use in a handheld weapon, comprising:
- a housing with a first end, a second end, and a longitudinal axis defined therebetween with a first length, the housing comprising;
a hollow portion extending a first predetermined distance between the first end and the second end;
a base positioned at the second end; and
a cylindrical portion positioned between the first end and the base, wherein the cylindrical portion comprises a plurality of angled relief cuts and a plurality of angled driving bands; and
an insert with a forward end, a rear end, and a longitudinal axis defined therebetween with a second length, the insert comprising;
a cylindrical body;
a nose portion at the forward end and integrally interconnected to the cylindrical body, wherein the nose portion tapers outwardly from a tip such that a diameter of the nose portion increases from the tip to the cylindrical body; and
a plurality of cutout portions cut into a surface of the insert and originating a second predetermined distance from the forward end and extending along the cylindrical body a third length, wherein each cutout portion in the plurality of cutout portions forms a curved trough with a radius of curvature, and wherein a lowermost portion of each of said curved troughs is positioned at an angle of between 5 degrees and 45 degrees with respect to the longitudinal axis of the insert;
wherein the insert is positioned within the hollow portion of the housing, and wherein the longitudinal axis of the insert is substantially parallel with the longitudinal axis of the housing.
