As mavracer mentioned, bullet momentum will often be more important than kinetic energy of the bullet, especially for penetration. Mass is the more important component for momentum and velocity is the more important component for kinetic energy. You can see this in the formulas where M is mass and V is velocity:

Kinetic Energy = 1/2M x V2

Momentum = M x V
