Abstract: A jacketed structure includes at least one penetrator slug; a jacket surrounding the at least one penetrator slug; and a deformable sleeve surrounding a portion of the at least one penetrator slug and encased by the jacket. The deformable sleeve includes porous material, which absorbs plastic deflection of the jacket during an engraving process with a barrel of a weapon during firing. The at least one penetrator slug includes material having a hardness value greater than a hardness value of the jacket and the deformable sleeve. The deformable sleeve surrounds a rear portion of the at least one penetrator slug. The deformable sleeve surrounds approximately half of the at least one penetrator slug. The deformable sleeve is configured to deform symmetrically during firing of a weapon containing the jacketed structure.
