To bring about high density state of a small spherical metal material by employing a heavier metal, e.g. tungsten, than lead in a bullet, e.g. a shot, a rifleshot or an air gunshot, and filling a shell with multiple small spherical balls composed of a heavier metal, e.g. tungsten, than lead while pressing.

The bullet comprises a shell 1 having front face closed by press, and a small spherical metal material 2. The bullet, e.g. a shot, a rifleshot or an air gunshot, is made of a heavier metal 2, e.g. tungsten, than lead in the form of small spherical bodies which are inserted into the shell 1 having front face closed by press.
