A bullet for law enforcement and personal defense use capable of meeting current FBI and IWBA standards and comprised of a jacket of malleable metal having a cylindrical side wall, tapered nose portion, an open forward end, and a plurality of deep longitudinally extending scores formed in the nose portion and defining petals therebetween which extend rearwardly from its mouth, and a malleable core mounted within the jacket and having a plurality of separate segments extending forwardly from its cylindrical base into the nose portion of the jacket and terminating adjacent said open jacket end in a shallow hollowed point, the bullet being capable of piercing substantial barrier materials before entering its target and thereafter expanding radially to about 1.5-2.0 times its diameter, while traveling 9-16 inches within its target.

1. A bullet comprising:(a) a malleable core having a generally cylindrical one piece base portion and a nose portion, the nose portion having a plurality of physically separate swaged core segments extending forwardly from the base portion and circumferentially arranged about the longitudinal axis of the base portion and cooperatively defining a hollow-point at their forward ends, the swaged separate core segments defining weakening planes between each of the segments;(b) a jacket formed of a malleable material and surrounding the core, the jacket having a base, a nose and an open forward end, the jacket nose having a plurality of circumferentially spaced scorings where each pair of scorings defines a petal, each of which is separate from and disposed radially opposite and outwardly of one of said segments in cooperative-position to expand radially, and where the weakening planes of the core are aligned with the scorings of the jacket. 2. The bullet of claim 1 wherein the jacket nose has an inner and an outer wall, the scorings positioned on the outer wall. 3. The bullet of claim 1 wherein the jacket nose has an inner and an outer wall, the scorings positioned on the inner wall. 4. The bullet of claim 1 wherein the jacket nose has an inner and an outer wall, the scorings positioned on both the inner and outer walls, the scorings being radially aligned. 5. The bullet defined in claim 1, wherein upon the bullet striking a viscous target, each of the petals is moved outwardly and rearwardly by one of the segments, which greatly expands the radial compass of the bullet. 6. The bullet defined in claim 1, wherein the hollow point is comprised of a cavity having an angled wall the angle of which, relative to the longitudinal axis of the bullet, is within about a 30°-50° range. 7. The bullet defined in claim 1, wherein the jacket has a variable wall thickness which increases from the nose toward the base of the jacket. 8. The bullet defined in claim 1, wherein the hollow point has a generally conical shape. 9. The bullet defined in claim 1, wherein the segments separate along the weakening planes and cause the petals to expand radially, upon the bullet striking a viscous target. 10. The bullet defined in claim 1, wherein the jacket has a uniform wall thickness. 11. The bullet defined in claim 1, wherein the jacket is made principally of a metal taken from a group of metals including copper, aluminum, tungsten, tin, brass, zinc, steel, iron or alloys thereof. 12. The bullet defined in claim 1, wherein the core is made principally of materials taken from a group including lead, tungsten, tin, zinc, polymers, or alloys thereof. 13. The bullet defined in claim 1, wherein the core is mainly polymeric. 14. A bullet for optimal penetration and expansion for law enforcement and personal defense use comprising:(a) a malleable bullet core having a generally cylindrical one-piece base portion;(b) said core having a plurality of physically separate radially-expandable, inter-engaging, swaged nose-forming core segments extending forwardly from said base portion and disposed in circumferentially arranged relation about the longitudinal axis of said cylindrical base portion and cooperatively defining a barrier material-shedding hollow-point at their forward ends and said swaged core segment defining weakening planes between each of said segments;(c) a jacket formed of a malleable material and surrounding said core and having a plurality of adjacent nose-and-mouth-defining petals, each of which is separate from and disposed radially opposite and outwardly of one of said segments in cooperative-position to expand radially; and(d) said petals being defined by a plurality of circumferentially spaced deep scorings in said jacket which extend longitudinally of said jacket and wherein the weakening planes of the core are aligned with the scorings of the jacket. 15. The bullet defined in claim 14, wherein upon said bullet striking a viscous targe t, each of said petals is moved outwardly and rearwardly by one of said segments, which expands the radial compass of the bullet. 16. The bullet defined in claim 14, wherein said hollowed point is comprised of a cavity having an angled wall the angle of which, relative to the longitudinal axis of said bullet, is within about a 30°-50° range. 17. The bullet defined in claim 14, wherein said jacket has a forward end and a rearward portion and a variable wall thickness which increases from said forward end toward the rearward portion of said jacket. 18. The bullet defined in claim 14, wherein said hollowed point has a generally conical shape. 19. The bullet defined in claim 14, wherein said jacket includes a cylindrical wall and further wherein upon said bullet striking a viscous target, said segments and said petals expand radially to a point at least adjacent the forward-most area of said cylindrical wall. 20. The bullet defined in claim 19, wherein said jacket has a uniform wall thickness. 21. The bullet defined in claim 14, wherein said segments separate along said weakening planes and cause said petals to expand radially, upon said bullet striking a viscous target. 22. The bullet defined in claim 14, wherein said jacket is made principally of a metal taken from a group of metals including copper, aluminum, tungsten, tin, brass, zinc, steel, iron or alloys thereof. 23. The bullet defined in claim 14, wherein said core is made principally of materials taken from a group including lead, tungsten, tin, zinc, polymers, or alloys thereof.
