Abstract: A highly separable bullet which disintegrates in a controlled fashion is provided, which highly separable bullet comprises a bullet core and a jacket, and which highly separable bullet is fabricated by method comprising a three step low-impact swaging process. A highly separable bullet is provided which easily, consistently, and predictably separates, fragments and disintegrates in a controlled fashion after entering soft tissue, water or ballistic geletin as such. The first step bullet core swaging process is a low-impact swaging process comprising placing a preselected number of a plurality of malleable strands of metal in a bullet core swaging die and swaging the plurality of malleable strands of the bullet core into a cylindrical core having a unique, uniform interlocking pattern between the plurality of malleable strands of metal.
