Abstract

A dummy cartridge or ammunition is disclosed comprising a cartridge case containing a case floor portion, a substantially cylindrical case wall, a substantially conical shoulder portion and a mouth portion. A dummy body member or projectile is inserted into the cartridge case and bears against the case floor portion. Means serve for securing one end of the dummy body member to the floor portion of the cartridge case, whereas a further portion of the dummy body member is attached to the mouth portion of said cartridge case. The dummy body member possesses a substantially cylindrical hollow compartment having a forward portion. An adjustable trim body is inserted into the forward portion of the hollow compartment, in order to place the center of gravity of the dummy cartridge at a predetermined desired position.
