Bullet
A bullet having a jacket, having a rear section, and a front section, having an open front end; a rear core disposed in the rear section of the jacket and bonded thereto; and a front core, separate from the rear core, disposed in the front section of the jacket, adjacent the open front end. The front section of the jacket can expand after impact with the target and release the front core to form an initial volume of disruption, while the rear core and at least the rear section of the jacket penetrate, past the initial volume of disruption.
1. A bullet comprising:
a jacket, the jacket having a rear section, a front section, and an interior surface, the front section of the jacket having an open front end;
a rear core disposed in the rear section of the jacket and bonded thereto;
a front core, separate from the rear core, disposed in the front section of the jacket, the front core being unbonded to either the jacket or the rear core,
a space inside the jacket adjacent the front core communicating with the open front end of the jacket facilitating the expansion of the jacket when the bullet strikes a target;
at least one notch formed on the interior surface of the jacket adjacent the juncture between the front section and the rear section; the at least one notch defining an area of reduced thickness for facilitating the expansion of the jacket and the release of the front core to form an initial volume of disruption after impact with the target, with the rear core and at least the rear section of the jacket, penetrating past the initial volume of disruption.
2. The bullet according to claim 1 wherein the rear section of the jacket is closed.
3. The bullet according to claim 1 wherein the rear core and the front core are made of different materials.
4. The bullet according to claim 1 wherein the rear core and the front core are made of the same material.
5. The bullet according to claim 1 wherein the jacket is made of copper or a copper alloy.
6. The bullet according to claim 1 wherein the front and rear cores are made of lead or a lead alloy.
7. The bullet according to claim 1 wherein the front core is made of a friable material.
8. The bullet according to claim 7 wherein the friable material is made from consolidated powdered metal.
9. The bullet according to claim 1 wherein the jacket is thicker adjacent the rear core than adjacent the front core.
10. The bullet according to claim 9 wherein the thickness of the jacket adjacent the rear core is at least 200% of the thickness of the jacket adjacent the front core.
11. A bullet comprising:
a jacket, the jacket having a rear section, a front section, and an interior surface, the front section having an open front end;
a rear core disposed in the rear section of the jacket and bonded thereto;
a front core, separate from the rear core, disposed in the front section of the jacket, the front core being unbounded to the jacket and the rear core; and
a space inside the jacket adjacent the front core communicating with the open front end of the jacket facilitating the expansion the jacket when the bullet strikes a target, so that the open front end of the jacket opens the front section of the jacket after impact with the target and releases the front core to form an initial volume of disruption with the rear core and at least the rear section of the jacket penetrating past the initial volume of disruption.
12. The bullet according to claim 11 wherein the rearward section of the jacket is closed.
13. The bullet according to claim 11 wherein the rear core and the forward core are made of different materials.
14. The bullet according to claim 11 wherein the rear core and the forward core are made of the same material.
15. The bullet according to claim 11 wherein the jacket is made of copper or a copper alloy.
16. The bullet according to claim 11 wherein the forward and rearward cores are made of lead or a lead alloy.
17. The bullet according to claim 11 wherein the forward core is made of a friable material.
18. The bullet according to claim 11 wherein the friable material is made of consolidated powdered metal.
19. The bullet according to claim 11 wherein the jacket is thicker adjacent the rear core than adjacent the front core.
20. The bullet according to claim 19 wherein there is a smooth tapering transition between the thicker wall thickness adjacent the rear core and the thinner wall thickness adjacent the front core.
21. The bullet according to claim 20 wherein the thickness of the jacket adjacent the rear core is at least 185% of the thickness of the jacket adjacent the front core.
22. The bullet according to claim 21 wherein the thickness of the jacket adjacent the rear core is at least 200% of the thickness of the jacket adjacent the front core.
23. The bullet according to claim 21 wherein the thickness of the jacket adjacent the rear core is 214% of the thickness of the jacket adjacent the front core.
24. The bullet according to claim 11 wherein the rear core penetrates to retain at least 50% of the original mass of the bullet.
25. The bullet according to claim 11 wherein the rear core penetrates to retain at least 65% of the original mass of the bullet.
