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.
