Abstract
A projectile may be formed having a caliber in the range from 4.6 mm to 20 mm for ammunition. The projectile may be a deformation bullet, a partial fragmentation bullet, a partial or full jacket bullet, a hard-core bullet or tracer bullet. The projectile may be formed by cold forming, in particular extrusion, from an intermediate with a tube section of substantially constant wall thickness, which constitutes at least 50% of the longitudinal extension of the intermediate.
Claims20
A projectile for ammunition, comprising:
- a central cavity;
- and
- a bullet jacket surrounding the central cavity, the bullet jacket including a bullet front tapering in an ogive-like manner and an adjoining bullet rear with a solid rear portion leading to a bullet bottom, wherein the projectile is formed cold forming from an intermediate with a tube section of constant wall thickness, which constitutes at least 50% of the longitudinal extension of the intermediate.
A tool for pressing an intermediate inserted in a die having a tube section with a cavity of constant diameter to produce a projectile, the tool comprising:
- a holding section;
- and
- a tapering forming section including:
- a tip,
- an elongated guide part adjoining the tip and configured to guide the tool within the cavity of the tube section, wherein the guide part is at least sectionally curved and concave-shaped or conically-shaped, and
- a press part adjoining the elongated guide part in a projection-free manner, the press part being at least sectionally curved and concave-shaped or conically-shaped, wherein the press part has a different inclination to a longitudinal axis of the tool.
A method of producing a projectile, comprising:
- inserting an intermediate including a tube section of constant wall thickness into a die, and
- cold forming the intermediate using a tool such that, at least sectionally, an outer diameter of the intermediate remains constant and determines the projectile caliber.
