A finless projectile provides improved ease of use, aerodynamics, muzzle velocity, drag, target, and excursion accuracy, structural integrity, terminal effectiveness and safety, at lower cost. The finless projectile includes a slug, a forward projectile body, an aft projectile body, an obturator, and a pad. The finless projectile is a full bore projectile that defines a hollow core, but does not include a sabot nor does it carry explosives. The finless projectile functions by kinetic energy transfer from the projectile to the target by deforming the target. The center of gravity of the finless projectile is forward of the center of pressure to provide static stability to the finless projectile.

What is claimed is: 1. A finless projectile for firing from a barrel of a weapon, to impart kinetic energy to a target, comprising: an inner hollow core; a slug including a cylindrical body and a tip; a cylindrical forward projectile body that forms the inner hollow core and that includes a front open end and an aft open end, wherein when assembled, the front open end integrally engages the cylindrical body of the slug; a generally cylindrical aft projectile body that forms the hollow core and that includes a front open end and a closed aft end, wherein when assembled, the front open end integrally engages the forward projectile body; an obturator disposed between the forward projectile body and the aft projectile body, wherein the obturator seals propellant cases inside the weapon; wherein the finless projectile is full bore so that a cross-section of the forward projectile body approaches a cross-section of the barrel, thus eliminating the need for a sabot; wherein the finless projectile includes a center of gravity and a distinct center of pressure, wherein the center of gravity is disposed forward of the center of pressure, in order to provide static stability to the finless projectile; and wherein the tip of the slug has a truncated bullet shape to transfer the kinetic energy to the target, wherein the aft projectile body comprises an aft circumferential flange with grooves that are disposed at an angle relative to a longitudinal axis of the finless projectile, in order to induce spin during flight, wherein the finless projectile further comprises a pad that attaches to the aft surface of the aft projectile body, in order to absorb forces on the projectile from mechanical contact. 2. The finless projectile of claim 1, wherein when the projectile is assembled, the slug has an outer diameter that is smaller than an outer diameter of the forward projectile body, to provide a circumferential shoulder between the slug and forward projectile body. 3. The finless projectile of claim 2, wherein the tip of the slug is frontal to the forward projectile body, in order to concentrate the weight of the finless projectile to the front. 4. The finless projectile of claim 1, wherein the aft section of the aft projectile body has an outer diameter that is smaller than an outer diameter of the aft circumferential. 5. The finless projectile of claim 1, wherein the optimal number of grooves ranges between 3 and 8 grooves. 6. The finless projectile of claim 1, wherein the slug is made of stainless steel. 7. The finless projectile of claim 1, wherein the forward projectile body is made of aluminum. 8. The finless projectile of claim 1, wherein the aft projectile body is made of aluminum. 9. The finless projectile of claim 1, wherein the obturator is made from a class of material comprising plastic and nylon. 10. The finless projectile of claim 1, wherein the pad is made of rubber.
