I didn't say a bullet loses energy to gravity. I said it affects the flight path. And if you think beyond high school physics for a second, you will realize that gravity does take away energy away from the collision if the target is at a higher elevation than the gun. The potential energy is useless in that situation. All that matters is kinetic energy.
