Method and apparatus for self-destruct frangible projectiles
The present invention discloses and claims an apparatus and method for delivering a wide array of selected agents to a target from stand-off distances. The apparatus includes a self-destruct frangible projectile made of primary, binding, and active components. The primary component generally has a specific gravity greater than lead, and the binding component generally has a specific gravity less than lead. The active component may be a metal for penetrating the target, a dye for optically marking the target, or another specially selected agent for delivery to the target, depending on the particular embodiment. The frangible projectile self-destructs upon contact with the target, in proximity to the target, or after passing the target, depending on the particular embodiment.

iii. wherein said primary component and said binding component are cold-pressed together to form said ballistic shape;
b. a penetrator in said longitudinal bore of said ballistic shape;
c. an explosive charge proximate to said penetrator; and
d. a detonator operatively connected with said explosive charge for igniting said explosive charge at a predetermined time, distance, or rotation of travel of said frangible projectile.
2. The self-destruct frangible projectile as in claim 1 , wherein sad primary component comprises particles having a diameter between approximately 0.001 and 0.040 inches.
3. The self-destruct frangible projectile as in claim 1 , wherein said frangible projectile has a specific gravity approximately equal to lead.

10. The self-destruct frangible projectile as in claim 1 , further including a full-metal jacket surrounding said front end of said ballistic shape.
11. The self-destruct frangible projectile as in claim 1 , further including a nose-piece proximate said front end of said ballistic shape.
12. A self-destruct frangible projectile comprising:
a. a ballistic shape having a front end, a distal end, and a longitudinal bore in said distal end, said ballistic shape comprising
i. a primary component having a specific gravity greater than lead;
ii. a binding component having a specific gravity less than lead; and
iii. a penetrator;
iv. wherein said primary component, said binding component, and said penetrator are cold-pressed together to form said ballistic shape;
b. an explosive charge in said longitudinal bore of said ballistic shape; and
c. a detonator operatively connected with said explosive charge for igniting said explosive charge at a predetermined time, distance, or rotation of travel of said frangible projectile.
