Abstract

A projectile structured to be discharged from a firearm includes a body having a nose portion and a tail portion separable from one another when the projectile strikes a target. The body further includes an interface disposed intermediate opposite ends of the body of the projectile structured to removably interconnect the nose and tail portions. Separation of the nose and tail portions such as when striking a soft tissue is caused by the tumbling of the projectile and the cooperative structuring of the interface to facilitate separation of the nose and tail portions. The interface is disposed, dimensioned and structured to define the primary area of contact of the projectile body with the rifling or interior surface of the barrel of the firearm. Another embodiment includes one of the nose or tail portions structured to contain a supplemental payload that is carried to the target upon discharge of the firearm.

Claims

1. A projectile structured to be discharged from a firearm, said

projectile comprising:

a body comprising a nose portion and a tail portion,

said body further including an interface portion disposed intermediate opposite ends of said body in interconnecting relation to said nose and tail portions,

said interface portion structured to provide controlled rupturing of said interface portion responsive to said projectile striking a predetermined target,

said interface portion disposed and dimensioned to define a reduced area of contact of said body with the rifling of the firearm, said interface portion maintaining the nose portion and tail portion in synchronized rotation while being fixedly secured to one another by said interface portion whereby upon said projectile striking said predetermined target said interface portion ruptures thereby separating said nose and tail portions of said projectile; and

and at least one of said nose and tail portion structured to carry a supplemental payload.

2. A projectile as recited in claim 1 wherein said body is structured to separate said nose and tail portions and expose the supplemental payload upon said body striking a predetermined target.

3. A projectile as recited in claim 2 wherein said body is further structured to separate said nose and tail portions at a location adjacent said interface.

4. A projectile as recited in claim 3 wherein said interface is removably connected to said nose and tail portions.

5. A projectile as recited in claim 3 wherein said interface is rupturable upon said body striking at least a predetermined target.

6. A projectile as recited in claim 1 wherein said tail portion is structured to carry the supplemental payload.

7. A projectile as recited in claim 6 wherein said tail portion comprises a cavity formed therein, said cavity dimensioned and configured to contain the supplemental payload.

8. A projectile as recited in claim 7 wherein said cavity is disposed adjacent a front face of said tail portion.

9. A projectile as recited in claim 7 wherein said cavity is disposed adjacent said interface.

10. A projectile as recited in claim 9 wherein said tail portion is at least partially separable from said interface to expose the supplemental payload.

11. A projectile as recited in claim 10 wherein said interface is ruptiurable upon striking a predetermined target.
