The 110JHP used by Treasury (Super-Vel and later Federal) was tested and designed to dump all the energy into the target, without exiting the target. The wound cavity was replicated using "gel blocks" and with the aid of high speed photography. The damage recorded during testing indicated that the ammo would be very effective in close quarters man-to-man combat situations. The criteria was not to penetrate car doors, windshields, or engine blocks. It was and is strictly a man stopper which can do considerable damage. Don't get in front of one.
