Abstract

A projectile core is provided formed from a carrier and a colorant. The carrier and colorant are mixed into a core mixture, which is formed into a predetermined core shape. The core mixture is cured until substantially firm, such as by drying, heating or freezing. An outer layer may be formed adjacent the surface of the projectile core by heating. An outer coating may also be applied to the projectile core. A method of forming a projectile core comprises: (a) mixing a carrier and a colorant to form a core mixture; (b) forming the core mixture into a predetermined core shape; and, (c) curing the core mixture until a substantially firm projectile core is formed.

Claims

1. A projectile, comprising:

a substantially spherical core including a carrier and a colorant mixed together and formed into a substantially firm predetermined core shape that is retained by the projectile core prior to impact of the projectile core upon a target; and

,

a generally uniform coating bonded to and enveloping the core, the coating conforming to the shape of the core and providing resistance against breakage of the projectile core prior to impact of the projectile core;

at least a portion of the coating and core adapted to disintegrate or disperse upon impact with a target.

2. The projectile core of claim 1, wherein the colorant is at least one of a pigment and a liquid dye.

3. The projectile core of claim 1, wherein the carrier comprises one of a fibrous, absorbent material and a powder.

4. The projectile core of claim 1, wherein the carrier comprises a plant fiber.

5. The projectile core of claim 1, wherein the carrier comprises a cellulosic material.

6. The projectile core of claim 5, wherein the cellulosic material comprises rice straw.

7. The projectile core of claim 1, wherein the carrier comprises a powder.

15. The projectile core of claim 1, wherein the carrier comprises a powder.

16. The projectile of claim 1, wherein the generally uniform coating comprises a wax coating.

18. The projectile of claim 1, wherein the projectile is a paintball.

8. A projectile for marking a target, comprising:

a substantially spherical projectile core comprising a carrier and a colorant mixed together and formed into a substantially firm predetermined core shape that is retained by the projectile core prior to impact of the projectile core upon a target; and

a generally uniform coating bonded to and enveloping the core, the coating conforming to the shape of the core and providing resistance against breakage of the projectile core prior to impact of the projectile core.

9. The projectile core of claim 8, wherein the colorant is one of a pigment and a liquid dye.

10. The projectile core of claim 8, wherein at least a portion of the projectile core is adapted to disintegrate or disperse upon impact with a target.

11. The projectile core of claim 8, wherein the carrier comprises at least one of a fibrous, absorbent material and a powder.

12. The projectile core of claim 8, wherein the carrier comprises a plant fiber.

13. The projectile core of claim 8, wherein the carrier comprises a cellulosic material.

14. The projectile core of claim 13, wherein the cellulosic material comprises rice straw.

17. The projectile of claim 8, wherein the generally uniform coating comprises a wax coating.

19. The projectile of claim 8, wherein the projectile is a paintball.

20. A paintball, comprising:

a substantially spherical core comprising a powder formed into a substantially firm predetermined core shape that is retained by the paintball core prior to impact of the core upon a target; and

a wax coating enveloping the core, the wax coating conforming to the shape of the paintball core and providing resistance against breakage of the paintball core prior to impact;

at least a portion of the wax coating and paintball core adapted to disintegrate or disperse upon impact with the target.

21. The paintball of claim 20, wherein the paintball is approximately 0.4- 0.75 caliber in size.
