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.
