Abstract: A gun firing method whereby four projectile segments that are contained in a cartridge case are fired simultaneously which creates a predetermined square pattern on a target to increase the hit probability of the dispersion. Two sets of projectile segments that are contained in the cartridge case, are fired by a gun, spin around the central longitudinal axis of each projectile segment, and provide a powerful square salvo of projectile segments. The dispersion produces a substantial increase in the hit probability when compared to a single shot.

Abstract: A gun firing method whereby 4 projectile segments that are contained in a cartridge case are fired simultaneously which creates a predetermined square pattern on a target to increase the hit probability of the dispersion. In the primary embodiment of the invention two sets of side by side projectile segments that are contained in the cartridge case are fired by a gun, spin around their fore and aft axis, and provide a powerful square salvo. The dispersion produces a substantial increase in the hit probability when compared to a single shot.

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.
