  • Publication number: 20240302145
    Abstract: The present invention relates to a projectile, in particular deformation and/or partial fragmentation bullet, comprising an essentially cylindrical projectile tail, an adjoining bow sided projectile head with an essentially central opening which opens into a cavity that extends axially from the projectile head in the direction of the projectile tail, preferably into the projectile tail, which has a cavity bottom and is bounded by a wall, and an tear-off groove introduced into the wall and, at least partially surroundings the cavity, which is arranged at a distance of at least 10% of the longitudinal extension of the cavity from the cavity bottom and has a radial depth of at least 10% of a caliber diameter and/or of at least 30% of a radial wall thickness of the wall surrounding the cavity.

  • Patent number: 12000682
    Abstract: 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.

  • Patent number: 11953300
    Abstract: Metallic solid projectile for practice cartridges, in particular for use on preferably police shooting ranges, wherein the solid projectile comprises a front-side ogival portion and a cylinder portion for holding the solid projectile in a cartridge case and defines a projectile length in the axial direction, wherein the ogival portion has an ogival wall and a rotationally symmetrical ogival cavity circumferentially bounded by the ogival wall, wherein it is provided that a fully cylindrical stem portion of the solid projectile extends in the axial direction over less than 45% of the projectile length.
