Expanding bullet
An expanding bullet having a one-piece structure has a cylindrical section and a section that is essentially shaped as a truncated cone, with the bullet tip being situated at the end of the latter section, which end faces away from the cylindrical section, and at least one planned breaking point being formed in this section, wherein the section shaped as a truncated cone is divided into segments and has a channel that has a mouth in the region of the bullet tip, wherein the channel has a bell-shaped widened region, which has its greatest diameter in the region of the transition from the cylindrical section to the section shaped as a truncated cone.
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.
2. The method according to claim 1 , wherein the channel has a bell-shaped widened region, a greatest diameter of the bell-shaped widened region being in a region of transition from the cylindrical section to the truncated-cone-shaped section.
3. The method according to claim 1 , wherein the solid material is wire, the processing of the solid material comprising cutting the wire to length using a massive-forming machine and/or center-punching the wire at one end face with a graining tool.
4. The method according to claim 1 , wherein the processing of the solid material comprises forming a central depression in the end of the truncated-cone-shaped section, the splitting starting from the central depression.
5. The method according to claim 1 , wherein the depth corresponds to a transition from the cylindrical section to the truncated-cone-shaped section.
6. 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
the processing of the solid material further comprises closing a bullet mold after forming the central recess, the segments being bent over in a direction of a central axis of the expanding bullet to form the channel.
7. The method according to claim 6 , wherein the central recess is formed using a pin, the bullet mold being closed after extracting the pin from the solid material.
8. The method according to claim 6 , wherein
the processing of the solid material further comprises forming at least one flaw on a mantle surface of the truncated-cone-shaped section when the bullet mold is closed.
9. The method according to claim 6 , wherein the processing of the solid material comprises:
splitting the end of the truncated-cone-shaped section into the segments;
penetrating, starting from the split end, into the truncated-cone-shaped section to a depth to form a central recess in the split end of the end of the truncated-cone-shaped section; and
closing a bullet mold after forming the central recess to press the segments in a direction of a central axis of the expanding bullet to form the channel.
10. The method according to claim 9 , wherein the depth corresponds to a transition from the cylindrical section to the truncated-cone-shaped section.
11. The method according to claim 9 , wherein the channel has a bell-shaped widened region, a greatest diameter of the bell-shaped widened region being in a region of transition from the cylindrical section to the truncated-cone-shaped section.
