1. A reloadable munition comprising: a reusable shell base having a hollow cavity on a bottom face;a reusable projectile that can be inserted into an end of the reusable shell base opposite from the hollow cavity, the projectile having a nose portion that is made from a high impact material that will withstand repeated firings and impacts without shattering, the projectile having at least one void space on a surface of the nose portion or extending into the nose portion of the projectile;a propulsion system reload inserted into the hollow cavity of the shell base; andmeans for mechanically retaining the propulsion system reload in the shell base for loading and firing of the munition. 2. The munition of claim 1 wherein the propulsion system reload is a high/low pressure propulsion system having a propellant charge, a primer, a rupture disk and a vent hole separating a high pressure chamber from a low pressure chamber in the shell base. 3. The munition of claim 1 wherein the mechanical means of retaining the propulsion system reload is a set screw that is threaded into a hole and a side of the shell base running perpendicular to a longitudinal axis of the shell base. 4. The munition of claim 1 wherein the projectile has a plurality of void spaces on a surface of the projectile around a nose portion of the projectile. 5. The munition of claim 4 wherein the void spaces extend parallel to a longitudinal axis of rotation of the projectile. 6. The munition of claim 4 wherein the void spaces are perpendicular to a longitudinal axis of rotation. 7. The munition of claim 1 wherein the projectile has a plurality of void spaces extending into the projectile in a nose portion of the projectile. 8. The munition of claim 7 wherein the void spaces extend into the nose portion at an angle to a longitudinal axis of rotation. 9. The munition of claim 1 wherein the projectile has a driving band positioned between a nose portion and a body portion. 10. The munition of claim 1 wherein the projectile has a body portion having a hollow cavity extending from an end surface and an angled exterior surface adjacent the end surface to increase stability of the projectile.
