Abstract

A gun firing method whereby multiple projectiles segments that are contained in a cartridge case are fired simultaneously to create a pattern on the target to increase the hit probability of the dispersion. Some of the multiple projectile segments are side by side within the cartridge case and have ends that are approximately 90 degrees to the central longitudinal axis of the cartridge. This causes the projectile segments to rotate around their for and aft axis upon leaving the gun barrel, improves their accuracy, and effectively provides the projectile segments with a higher ballistic coefficient and a higher sectional density, to strike the target at a higher velocity and with greater retained energy to efficiently penetrate the target. Rotationally orienting the cartridges in the chamber of the gun is a further embodiment that provides a predetermined symmetrical pattern of projectile segment strikes on the target to further increase the hit probability of the dispersion.

Claims

a gun having a rifled barrel;

a projectile having a main body, having a front end, a back end, and a side, positioned within a cartridge case, with a central longitudinal axis along the center of said cartridge case;

wherein said projectile is divided into at least three projectile segments;

wherein at least two of said projectile segments have centers of mass that are offset from the said central longitudinal axis of the cartridge and are positioned side by side totally within said cartridge case and said front ends and said back ends are approximately 90 degrees to said central longitudinal axis of the cartridge;

wherein a standard projectile segment, that has its center of mass along said central longitudinal axis of the cartridge is positioned at the forward end of said cartridge case;

whereby said standard projectile segment positioned forward promotes reliable loading, and upon firing simultaneously said forward standard projectile segment and at least two said projectile segments with ends approximately 90 degrees to said central longitudinal axis of the cartridge that are positioned side by side within said cartridge case, said projectile segments that were side by side thereby rotate around their fore and aft axis after leaving the gun barrel, providing accurate projectile segments that effectively have a higher ballistic coefficient, and a higher sectional density, and therefore strike said target at a higher velocity and with greater retained energy to efficiently penetrate said target to a greater depth and to create an accurate pattern on said target to increase the hit probability of said gun.
