Not for penetration, velocities below 1800 ft/s in steel and 1100 ft/s in Alum act about a 3/2 power while mass is only at a power of 1. It's more than energy that gets involved. It also involves shock waves and adiabatic shear. Fortunately Kevlar belts have a whole different mechanism going on at the engine level
