Abstract

A reactive material that includes at least one binder and at least one fuel, at least one oxidizer, or combinations thereof; at least one metal and at least one fuel; or at least two fuels. The reactive material is used in a reactive material shot shell in which at least a portion of a slug, shot, or combinations thereof are formed from the reactive material.
