Embodiment Construction

[0034]While the making and using of various embodiments of the present invention are discussed in detail below, it should be appreciated that the present invention provides many applicable inventive concepts that can be embodied in a wide variety of specific contexts. The specific embodiments discussed herein are merely illustrative of specific ways to make and use the invention and do not delimit the scope of the invention.

[0035]As used herein the term “shell,”“bullet” and “projectile” are used interchangeably and denote a projectile that is positioned in an ammunition cartridge until it is expelled from a gun, rifle, or the like and propelled by detonation of a powdered chemical propellant or other propellant that may be non-powdered, solid, gaseous or gelatin. And includes payload-carrying projectiles contains shot, an explosive or other filling, though modern usage sometimes includes large solid projectiles properly termed shot (AP, APCR, APCNR, APDS, APFSDS and proof shot).
