This shot consists of a solid steel body machined externally to form a double ogive. This contour is considered to result in greater penetration and better underwater ballistics. Penetration is also enhanced by heat treating the body of the shot. The after end of the body is recessed to form an empty cavity, and the base of this cavity is closed by a threaded spigot which screws into the shell ring of the rocket motor. The shot is painted black overall, with a 1 inch white tip and a 1/2 inch white band on the nose.
No information about functioning.
