Abstract

A practice projectile has a cylindrical casing having front and rear portions; a bottom section attached to the rear portion of the cylindrical casing; a frontal nose section including at least two subcomponents which have front and rear portions. The subcomponents can assume a closed position in which the projectile has an external configuration identical to that of a live projectile having the same caliber and an open position in which the subcomponents are in a spread-apart state at a given opening angle. The rear portion of the subcomponents is pivotally connected to the front portion of the cylindrical casing. There is further provided a device for holding the subcomponents together in the closed position prior to firing the projectile. The holding device is arranged to be overcome by centrifugal forces derived from a projectile spin subsequent to firing, to thereafter allow the subcomponents to assume the open position.
