Abstract
A projectileless ammunition system (20; 320) includes a metallic case (22; 322). A propellant charge (26; 326) is carried by the case and covered by an over-powder member (24; 324) in the absence of a separate projectile. The ammunition is advantageously used with an industrial ballistic tool operating so that each spent case serves as the effective projectile to be propelled by firing of the next round of ammunition.
Claims7
Ammunition for use with a discharging apparatus that includes a chamber for receiving the ammunition, a muzzle and a barrel between the chamber and the muzzle, the ammunition comprising:

- a propellant charge;
- a primer mounted in an aft portion of the case;
- and
- a cover engaging said fore portion of said case and cooperating with the case to define a powder chamber to enclose both the propellant charge and an open forward volume, wherein a similar case is expelled from said muzzle on ignition of said propellant charge.
