Cartridge with combined effects projectile
A cartridge comprising a bullet, the bullet providing a radially expanding array of bullet fragments upon entering a target and also providing an increase in effective surface area of the bullet within the target by structural features that facilitate tumbling or mushrooming in the target. In an embodiment a pair of axial core members are aligned in a bullet jacket with the forward core member being segmented with separation junctures formed by engaged faces of adjacent segments. Impact causing fracturing of the segments from a base portion.

6. The handgun cartridge of claim 1 , wherein the jacket has a plurality of axially extending tear guides extending rearwardly from a forward margin, whereby when the bullet strikes a target the jacket may petal outwardly, wherein the plurality of axially extending tear guides are at least one of skives, folds, and slits.
7. The handgun cartridge of claim 1 , wherein the separations extend at least 30% of the axial length of the bullet at the outer surface of the core.
8. The handgun cartridge of claim 1 , wherein the separations extend at least 50% of the axial length of the bullet at the outer surface of the core.
9. The handgun cartridge of claim 1 , wherein the separations extend at least 60% of the axial length of the bullet at the outer surface of the core.
10. A handgun cartridge comprising:
a cartridge casing comprising a mouth and an interior, propellant in the interior of the cartridge casing, and a bullet secured in the mouth of the cartridge casing, the cartridge and bullet comprise a central axis, the bullet comprising an axial length, the bullet comprising:
a jacket member;
a core disposed inside the jacket member, the core comprising an outer circumferential surface; and
the core comprising a plurality of core segments spaced apart by portions of the core;
wherein the core has a plurality of axially extending separations between the core segments extending to the outer circumferential surface of the core, the separations extending at least 20% of the axial length of the bullet at the outer surface of the core.
11. The handgun cartridge of claim 10 , the plurality of core segments define a bullet tip comprising an axially extending recess at said tip.
12. The handgun cartridge of claim 10 wherein the core is comprised of lead.
13. The handgun cartridge of claim 10 , wherein the separations extend at least 30% of the axial length of the bullet at the outer surface of the core.
14. The handgun cartridge of claim 10 , wherein the separations extend at least 50% of the axial length of the bullet at the outer surface of the core.
15. The handgun cartridge of claim 10 , wherein the separations extend at least 60% of the axial length of the bullet at the outer surface of the core.
16. A cartridge comprising:
a cartridge casing comprising a mouth and an interior,
propellant in the interior of the cartridge casing, and
