Abstract
A sub-caliber projectile, having a detachable sabot means which comprises leading and trailing obturating members spaced apart along a longitudinal axis of the projectile and releasably secured thereto. A pressure cell is defined between the obturating members communication means being located in the trailing obturating member for effecting communication between the interior of the barrel and the pressure cell and being so designed that the maximum pressure generated in the pressure cell by the influx of propellant gases from the barrel and through the communication means during the launching of the projectile is substantially less than the maximum pressure generated in the barrel and exerted on the trailing obturating member.
