Title:
CAP FOR AN AMMUNITION PROJECTILE AND METHOD
Document Type and Number:
WIPO Patent Application WO2003002928
Kind Code:
B1
Abstract:
Method of manufacture of a multi-component projectile (14) for gun ammunition (16) including the steps of providing a uniformly spherical ball (18) of a ductile metal, either solid metal or a self-supporting pressed compact of metal powder particles, inserting the metal ball into the open end (10) of a cup-shaped jacket (54) which houses at least one core (30), the ball being disposed between that end of the core adjacent the open end of the jacket and the open end of the jacket. Axially directed pressure against the ball deforms the ball into a generally flat disc (36). Simultaneously, the core (30) may be seated within the closed end (26) of the jacket. Thereafter, the jacket/core/disc combination is die-formed to define an ogive (42) at the open end of the jacket. This action, among other things, deforms that end of the core adjacent the ogive, the disc and the open end of the jacket into the desired ogive geometry, the disc being deformed into a cap (70) of generally hollow hemispherical geometry and containing powder particles (50) from the core within the hollow of the cap.
