Expandable bullet
First Claim
1. A bullet comprising:
- a generally cylindrically-shaped body having a cavity disposed in the front end thereof, said cavity comprising a tapered front end adapted to mate with the head of a screw;
a centrally disposed cylindrical portion having an internal diameter greater than the diameter of the threads of said screw at the largest cross-section thereof;
a narrow portion near the rear end of said bullet having a diameter sufficiently narrow to secure the threads of said screw therein;
fault lines disposed in said body between said cavity and the exterior surface of said body, said fault lines extending from the front end of said body to a predetermined position along the length thereof;
a cavity disposed in the rear end of said body such that said bullet is substantially balanced at the midpoint along its longitudinal axis;
a screw disposed in said cavity with the head of said screw disposed adjacent the tapered portion of said cavity;
whereby when said bullet is fired from a firearm and strikes a target, said screw is threaded through said body such that said body expands in a fan-like manner to form blades out of the body from adjacent fault lines.

Abstract
A bullet is described having a series of slits disposed along the length thereof about the circumference of the bullet and through to a cavity disposed in the front of the bullet through the center. The cavity is comprised of three sections and is adopted to hold a screw having a generally tapered profile. The rear end of the bullet is provided with a cavity which balances the bullet longitudinally and provides a volume to permit the rear portion of the bullet to expand when the screw is threaded therethrough.
When the bullet is fired and strikes a target, the rotation of the bullet as a result of the rifling causes the screw to thread its way through the bullet thereby expanding the bullet along its slits into a fan-like configuration. The expanded bullet, and the whirling of the blades formed by the screw increases the destructive power of the bullet.
