1. A practice projectile consisting of a sabot which can be discarded after the gun phase and a sub-projectile (1) of the armour piercing, the projectile being constituted by a front penetrator body (7) fitted with a ballistic ogive (9) and outlet ports (12), and a rear penetrator body (6) possibly fitted with an aerodynamic tail unit (8), the front and rear bodies being interconnected by an elastic coupling (11) and actuated after a predetermined flight path, characterized in that it include a self-contained compressed gas holder (3) co-operating with a perforating striker (4) in order to generate a gas expansion inside an enclosure (2) housed in the front and rear bodies, the striker (4) and the gas holder (3) being located on both sides of the elastic coupling (11) and of the ports (12) which are closed by the interposition of either the striker (4) or the gas holder (3) during the perforation of the membrane (5) and then free when the striker (4) or the gas holder (3) returns to its original position.
