Ammunition constituted by a case containing a propulsive charge and a subcalibre projectile for a firearm, the projectile comprising: an internal element (5) an external element (6) and anti-recoil means (7) for the engagement of the internal element (5) in the external element (6), the internal element (5) comprising: a front part (8) with a stopping shape, a rear shank (9) connected to the front part, and a percussive mass (10) at least partly fitted over the rear shank (9), and the external element (6) being constituted by: an aerodynamically-shaped outer casing (19, 13) covering the front and the side walls of the internal element (5) in order to give the projectile good air-penetration, the anti-recoil engagment means (7) ensuring the connection of the internal element (5) and the external element (6) so that at least initially the external element cannot advance more rapidly than the internal element.
