Description: CROSS REFERENCE TO RELATED APPLICATION This application is a national stage application under 35 U.S.C. 371 of PCT Application No. PCT/US2010/055150 having an international filing date of Nov. 2, 2010, which designated the United States, the entire disclosure of each of which ishereby incorporated herein by reference. The present disclosure is generally directed toward projectiles for use with rifled barrels and methods of manufacturing the same.BACKGROUND It is well understood by those skilled in the art of weaponry that firearms typically fall into two separate families, those being: smooth bore and rifled bore. A smooth bore was the original design of all early firearms (cannons and hand heldguns) smooth bore barrels fire mono- or multi-projectile shot without inducing a spin. The most recognized non-spinning mono projectiles would be fired from a colonial smooth bore musket, (i.e., the sphere configuration dominated in popularity and thenthe min-ball (a more aerodynamically shaped version)). Due to the advent of the second member of the firearm family, the rifled barrel, a superior method of firing a mono-projectile with a predictable flight path was achieved and the practice of firingslugs form a smooth boor is all but forgotten. In contrast, most modern marksmen frequently use smooth bore barrels to fire non-spinning multi-projectile shot as buckshot or birdshot, which are most often referred to as "scatter shot" due to the reliance on random events/influences to causea spreading out of the plurality of projectiles. This shot type was originally referred to as "scatter-shot" because it relies on random influences (e.g., wind, barometric pressure, temperature, velocity, collisions, turbulence, etc.) to achieve arandom but semi-predictable rate/pattern of ever expanding separation. As the plurality of projectiles travel down the barrel of the gun and further travel down range toward the target, the spreading out of the projectiles occurs randomly andsimul
