Subsonic Bullet

摘要

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/cm3, and in the nose with a material having a density greater than or equal to 11 g/cm3. 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.
