Abstract

Ammunition which includes a bullet having an effective caliber that is larger than its nominal caliber, comprised of a bullet body with a longitudinal cavity in the forward end, and one or more bores extending from the cavity to bore openings on the exterior of the bullet. In use, target media is gathered in the cavity and ejected under force through the bore openings, increasing the damage done by the bullet. Optional embodiments include filled, irritant payload, and jacketed embodiments.

Claims

1. A bullet, comprising:

a generally cylindrical body having

a tapered tip section having a forward end,

a longitudinal cavity aligned with a central longitudinal axis of the tapered tip section and having an open end at the tip section forward end, the longitudinal cavity having a cross-sectional area adjacent the open end, the cavity open end having an area, the cavity open end area being substantially equal to the cavity cross-sectional area open end, and an inner end enclosed within the body,

two bores connecting with and extending laterally from the inner end of the longitudinal cavity to bore openings; and

a releasable polymer filler packed into the longitudinal cavity and the two bores, said polymer filler being solidified within the cavity and bores and being releasable on impact to eject from the bores into a soft tissue target without mushrooming of the tip section forward end.

2. The bullet of claim 1, further comprising a frangible jacket fitted over the body, the jacket having an open end aligned with the longitudinal cavity open end.

3. The bullet of claim 1, further comprising a frangible jacket fitted over the body.

4. The bullet of claim 1, wherein the two bores extend from opposite sides of the longitudinal cavity.

5. The bullet of claim 1, wherein the two bores extend generally perpendicularly to the longitudinal cavity.

6. The bullet of claim 1, wherein the bullet has an effective caliber that is larger than a nominal caliber of the bullet.

7. A cartridge for firearms, comprising:

a cartridge case;

a primer;

a powder charge;

a generally cylindrical body having

a tapered tip section having a forward end,

a longitudinal cavity having a substantially open end at the forward end of the tip section and an inner end enclosed within the body,

one or more bores connecting with and extending laterally from the longitudinal cavity to bore opening(s); and

a releasable polymer filler packed in the longitudinal cavity or bores, or both said polymer filler being solidified within the cavity or bores and being releasable on impact to eject from the bores into a soft tissue target, without mushrooming of the tip section forward end.

8. The cartridge of claim 7, further comprising a frangible jacket fitted over the body.

9. The cartridge of claim 8, wherein the frangible jacket has an open end aligned with the longitudinal cavity open end.

10. The cartridge of claim 8, wherein the frangible jacket has opening(s) aligned with the bore opening(s).

23. The cartridge of claim 7, wherein the releasable polymer filler is packed into the longitudinal cavity and the one or more bores.

11. A bullet, comprising:

a generally cylindrical body having

a tapered tip section having a forward end,

a longitudinal cavity having an open end at the forward end of the tip section and an inner end enclosed within the body, the longitudinal cavity and the longitudinal cavity open end having similarly sized cross-sectional areas,

one or more bores connecting with and extending from the longitudinal cavity to bore opening(s); and

a releasable polymer filler packed in one or more of;

the longitudinal cavity and the one or more bores, said polymer filler being solidified within the cavity or bores and being releasable on impact to eject from the bores into a soft tissue target without mushrooming of the tip section forward end.

12. The bullet of claim 11, wherein the one or more bores connect with and extend from the inner end of the longitudinal cavity to the bore opening(s).

13. The bullet of claim 12, where there are two or more of the bores.

14. The bullet of claim 13, wherein there are two of the bores extending from the longitudinal cavity from opposite sides of the longitudinal cavity at locations 180 degrees apart.

15. The bullet of claim 11, wherein there are two of the bores extending from the longitudinal cavity and the two bores are aligned with each other.

16. The bullet of claim 11, wherein the one or more bores extend generally perpendicularly to the longitudinal cavity.

17. The bullet of claim 11, wherein the longitudinal cavity is aligned with a central longitudinal axis of the tapered forward tip section.

18. The bullet of claim 11, further comprising a frangible jacket fitted over the body.

19. The bullet of claim 18, wherein the frangible jacket has an open end aligned with the longitudinal cavity open end.

20. The bullet of claim 18, wherein the frangible jacket has opening(s) aligned with the bore opening(s).

21. The bullet of claim 11, wherein the bullet has an effective caliber that is larger than a nominal caliber of the bullet.

24. The bullet of claim 11, wherein the releasable polymer filler is packed into the longitudinal cavity and the one or more bores.

22. A bullet having a longitudinal cavity having a substantially open end at a forward end of the bullet and one or more laterally extending bores connecting with and extending from longitudinal cavity to bore openings, and a releasable polymer filler packed in the longitudinal cavity or bores, or both, said polymer filler being solidified within the cavity or bores and being releasable on impact to eject from the bores into a soft tissue target, without mushrooming of the tip section forward end, and having an effective caliber that is larger than a nominal caliber of the bullet.
