Reloadable training ammunition

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;

a propulsion system reload inserted into the hollow cavity of the shell base by hand using no presses or vises or tools other than a small hand tool; and

means for mechanically retaining the propulsion system reload in the shell base for loading and firing of the munition that is reversible and allows the propulsion system reload to be removed by hand using no presses or vises or tools other than a small hand tool.

2. The munition of claim 1 wherein the propulsion system reload is a high/low pressure propulsion system having a propellent charge, a primer, a rupture disc 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 in a side of the shell base running perpendicular to a longitudinal axis of the shell base.

4. The munition of claim 1 wherein the munition is a 40 MM non-lethal impact munition.

5. A reloadable munition comprising:

a reusable shell base having a hollow cavity on a bottom surface;

a reusable projectile inserted into a top portion of the shell base;

a propulsion system reload positioned in the hollow cavity of the shell base by hand using no presses or vises or tools other than a small hand tool; and

a set screw extending through the shell base to retain the propulsion system reload in the shell base.

6. The munition of claim 5 wherein the propulsion system reload is a high/low pressure propulsion system incorporating a propellant charge, a primer, a rupture disc and a vent hole separating a high pressure chamber from a low pressure chamber in the shell base.

7. The munition of claim 5 wherein the munition is a 40 MM non-lethal impact munition.
