A projectile having a reactive material disposed therein is provided. The projectile includes a housing which defines a cavity, the cavity being open at one end of thereof. A reactive material is disposed within the cavity. A tip is coupled with the housing and substantially encloses the opening of the cavity. The housing, the reactive material and the tip are cooperatively positioned and configured so as to define a void space between a surface of the tip and a surface of the reactive material. Upon impact with a target, the tip of the projectile is designed to become displaced within the cavity until it contacts the reactive material and transfers kinetic energy thereto, thereby causing ignition of the reactive material. The void space may be defined to provide a desired amount of time between initial impact of the projectile with a target and the subsequent ignition of the reactive material.
