Segmenting pistol bullet
A bullet having a generally cup-shaped jacket, a core disposed inside the jacket, and partially divided into a plurality of segments by a plurality of slits formed therein is mounted at the front of the jacket. A tip is mounted in the core. The tip has a plurality of notches formed its forwardly facing ogival surface; each notch having a forward end adjacent the forward end of the tip, and a rear end rearward of the rearwardly facing shoulder and the front end of the jacket, so that material from the target can enter the jacket and help open the jacket and release the core.
1. A bullet comprising:
a jacket, the jacket being generally cup-shaped with a closed rear end, an open front end, a generally cylindrical sidewall between the rear end and the front end with an inwardly tapering lip adjacent the front end;
a core disposed inside the jacket, the core being generally cylindrical with an axial passage extending from the rear end to the front end, and having a plurality of slits therein extending from the axial passage partway toward the exterior of the core, dividing the core into a plurality of separable segments joined by a web of material adjacent their outer surfaces; and
a tip, having a forwardly facing ogival surface tapering to a forward end, a rearwardly facing surface smoothly tapering to a generally cylindrical shank, the rearwardly facing surface conforming to the face of the core with the shank embedded in and frictionally engaging the core, and a rearwardly facing shoulder abutting the front end of the jacket forming a smooth transition therewith, and a plurality of notches formed in the forwardly facing ogival surface; each notch having a forward end adjacent the forward end of the tip, and a rear end rearward of the rearwardly facing shoulder and the front end of the jacket.
2. The bullet according to claim 1 where there are three notches formed in the forwardly facing ogival surface.
3. The bullet according to claim 2 wherein the notches equally spaced around the circumference of the core tip.
4. The bullet according to claim 3 wherein there are a plurality of scores in the jacket adjacent the front end.
5. The bullet according to claim 4 wherein the scores in the jacket are equally spaced circumferentially around the jacket.
6. The bullet according to claim 5 there are six scores in the jacket adjacent the front end.
7. The bullet according to claim 6 wherein the thickness of the jacket tapers from the rear end to the front end.
