Title:
FRANGIBLE BULLET
Document Type and Number:
WIPO Patent Application WO2003056270
Kind Code:
A3
Abstract:
A frangible hollow point bullet (10) is disclosed. The bullet (10) is formed from a frangible material such as sintered copper to provide a bullet-shaped body. A plurality of coaxial, substantially cylindrical cavities (23,24,25) having progressively decreasing bore diameters are formed in the nose of the bullet-shaped body, extending rearwardly therefrom, to provide a bullet (10) that both expands and fragments in a semicontrolled fashion upon impact with a target. In a preferred embodiment, at least one of the coaxial cavities (23,24,25) is multiply scored to provide a substantially symmetric fragmentation pattern and a controlled and uniform fragment size.
