A system is disclosed for decelerating a rifled projectile in flight. A gun bore rifled with a land pattern having a characteristic number of turns per bore diameter, has a muzzle at a first angular orientation along the projectile's flight axis and a characteristic recoil distance. A deceleration tube having an opened end is located at a separation distance from the gun muzzle along the flight axis. When the projectile is fired from the rifled gun, it has a rifle pattern engraved thereon and it travels along the flight axis undergoing rotational motion imparted by the rifle land pattern of the gun. The angular orientation of the deceleration tube causes the projectile to be brought into positive engagement with the rifled land pattern in the deceleration tube, so as to be decelerated without damaging the projectile. A pneumatic or hydraulic pressure can be efficiently brought to bear against the advancing projectile in the tube, by virtue of the accurate engagement of the projectile's engraved pattern with the rifle land pattern in the deceleration tube.
