Abstract

In a cartridge fitted with a gun-barrel projectile comprising a lead head and a resilient body joined to the head by a plug-in connection, the connection is designed to be a positive and exact fit, and the body is constructed with a forward end part adjacent the head, a rod-like central part, and a rearward end part in the form of a flat top piston connected to the central part at a predetermined breakage point whereby the rearward part can break from the central part and move forwards, hence moving the center of gravity of the projectile forwards, when the cartridge is fired.
