Abstract:
The invention here described of novel aerodynamics and construction has been shown to alleviate the problems inherent in subsonic ballistics, such as, but not limited to, tumbling in flight, loss of impact energy, as well as the changes in both accuracy and precision of the firearm shots fired at subsonic speeds. The subsonic bullet herein described has three main aerodynamic components that aid in subsonic flight: 1) a parabolic or hemispherical nose; 2) a cylindrical center length with parallel sides; 3) a cone-like parabolic tail with an optimized tail geometry to slowly converge the laminar flow around the bullet without introducing turbulence. These features serve to reduce air pressure and turbulent airflow around the bullet during flight.

Claim (Index 35):
A .308 bullet optimized for subsonic applications comprising:\n a. a parabolic nose defined by the equation: y 2 =4PX ; b. a nose section comprised of lead, where said nose section comprised of lead extends to 1.08 inches behind the tip of said parabolic nose, where the center of mass of said nose section is located .54 inches behind the tip of said parabolic nose, where the lead weight of said nose section is .0208 lbf.; c. a cylindrical midsection that is .308 inches in diameter, where said cylindrical midsection is of appropriate diameter to be utilized with a .308 caliber casing; d. a cone-like parabolic tail defined by the equation: y t = D 0.308 * [ \ue89e 0.01605 * ( x c ) 4 + 0.0322 * ( x c ) 3 - 0.1699 * ( x c ) 2 - 0.02335 * ( x c ) + 0.154 ] ; e. a tail section comprised of magnesium, where said cone-like parabolic tail and tail section extends into the interior of a .308 caliber casing; where the center of mass of said tail section is located 1.33 inches behind the tip of said parabolic nose, where said tail section magnesium weight is .0012 lbf.; f. an outer shell, wherein said outer shell is comprised of copper, where the center of mass of said outer shell comprised of copper is located .93 inches behind the tip of said parabolic nose, where said outer shell of copper weight is .0125 lbf.; g. where the center of mass of said .308 bullet is located .71 inches behind the tip of said parabolic nose; h. where the overall length of said .308 bullet is 2.08 inches; and i. where the weight of said bullet is .0345 lbf (241.5 grains).
