ABSTRACT:
A gun firing method whereby multiple projectiles segments that are contained within a cartridge are fired simultaneously in a symmetrical pattern. Some of the multiple projectile segments are modified by moving the center of mass of the projectile segments away from the central longitudinal axis of the cartridge. This in combination with bring fired from a rifled gun barrel will impart velocity to the modified projectile segments upon exiting the gun barrel at right angles to the gun barrel. This velocity along with the higher muzzle velocity will cause the modified projectile segments to diverge away from the trajectory of a standard projectile segment and strike the target away from the bullseye. The magnitude of the divergence will vary with the distance the projectile segment's center of mass is away from the central longitudinal axis of the cartridge. The placement of the modified projectile segments strikes around the bull's-eye will be determined by the orientation of the centers of mass of the modified projectile segments prior to firing. Simultaneously firing a multiplicity of standard and modified projectile segments will produce a symmetrical pattern on a target, which will substantially increase the hit probability of a gun.
