Subsonic Bullet

Abstract

A bullet whose aerodynamics is suitable for stable subsonic flight, including a parabolic or hemispherical nose section, cylindrical midsection, and a parabolic into conical tail section. It is constructed of a copper shell filled, in the tail, with a material having a density less than or equal to 3.0 g/cm 3 , and in the nose with a material having a density greater than or equal to 11 g/cm 3 . The bullet further includes a length sufficient to fill an appropriate standard casing combined with the proper amount of smokeless powder for subsonic flight. These characteristics allow for the bullet's stable and accurate flight at speeds below 343.2 m/s.

What is claimed is: 
     
         1 . A bullet for subsonic applications, aerodynamically comprising: a parabolic or hemispherical nose section, a cylindrical midsection of diameter such that the bullet fits snugly into a casing of appropriate caliber, and a parabolic into conical tail section. 
     
     
         2 . The bullet of  claim 1 , comprising physically of a copper shell, the tail filled with a material having a density less than or equal to 3.0 g/cm 3 , and the nose with a material having a density greater than or equal to 11.0 g/cm 3 . 
     
     
         3 . A method for loading the bullet of  claims 1  and  2 , comprising the use of smokeless powder within a standard casing such that the bullet, while being loaded into the casing with the appropriate amount of the smokeless powder, fills the casing, leaving limited air voids. 
     
     
         4 . The method of  claim 3  such that the amount of powder within the casing does not cause the flight speed of the bullet to exceed 343.2 meters per second when the primer is struck.
