An armor piercing projectile configuration which provides strength, rigidity and mass properties sufficient to permit long thin armor piercing cores to be fired from guns in a stable and accurate manner. The core is supported at both ends in such a way that a monocoque skin or shell provides rigidity and the space between the core and the shell is filled with rigid material or structure so as to support the core throughout substantially all of its length. The shell is of relatively high density adding to the lateraltransverse moment of inertia ratio to provide gyroscopic stability for the long thin core. Author
