Peetzakilla - the energy is most certainly -not- identical. See above. This is misinformation.

It most certainly is not. You are making assumptions about my statement that are not valid. Conservation of energy is an absolute, indisputable law of physics. Conservation of momentum can not be violated. The total energy of the system is a constant. The energy transfered by the bullet to the target is identical to the energy transfered to the gun and shooter, discounting loses than can all be essentially traced to friction and/or noise.
Your statement that "you are confusing momentum with energy" is misleading. Momentum
IS energy. It's not mathematically the same as KINETIC energy but it most certainly IS energy.
In fact, assuming a perfectly inelastic collision, the kinetic energy is perfectly converted to other forms of energy and is equally conserved.
