1. A method for producing an expanding bullet, comprising:
providing a solid material; and
processing, using massive forming, the solid material to produce the expanding bullet, wherein:
the expanding bullet has a cylindrical section and a truncated-cone-shaped section divided into segments, a bullet tip being situated at an end of the truncated-cone-shaped section that faces away from the cylindrical section;
the truncated-cone-shaped section includes at least one planned breaking point formed therein, and a channel having a mouth in a region of the bullet tip;
the processing of the solid material comprises splitting the end of the truncated-cone-shaped section into a plurality of segments and forming a central recess in the split end of the end of the truncated-cone-shaped section; and
forming the central recess comprises penetrating, starting from the split end into the truncated-cone-shaped section to a depth and pressing portions of the solid material towards the cylindrical section.
