  • Patent number: 7543535
    Abstract: Rifle bullet for hunting purposes, with a jacket of a lead-free soft ductile material and a core, connected to the jacket, made from a material softer than the jacket. The aim of the invention is to improve the bullet to provide a persistent cut of hair and bleeding at the point of entry, mushrooming in a controlled manner with considerable cross-sectional enlargement, whilst only marginally breaking up with a high residual weight (90% and more). The rifle bullet has a thinly-jacketed bullet tip and has a marked sharp edge at the transition point of the jacket on the bullet tip to a substantially thicker-jacketed tail section. The rifle bullet is internally provided with a circumferential channel reducing the wall thickness of the jacket at said point, filled with the core material.
