ABSTRACT:
In certain types of firearm competition bowling pin-like objects are shot at, with the goal of knocking them off of a platform. To accomplish this with conventional bullets having a standard tapered bullet requires great skill. This invention relaxes the precision requirement by using a bullet which has a sawtooth section cut from the face of the bullet. A bullet fired from a firearm normally rotates axially due to the rifling in the gun barrel. The rotation coupled with a sawtooth edged slug causes the bullet to penetrate the bowling pin-like object by boring into the surface. The kinetic energy of the bullet's forward movement impacts the bowling pin-like object moving it away from the line of fire. The kinetic energy of the bullet's rotational moment causes the bowling pin-like object to rotate about the axis of the bullet. The composite forces cause the pin to be knocked off the platform.
