As far as energy goes - now this is just my opinion but think about it - There is NO wasted energy when a ball/bullet exits a critter. The thing that drops a deer is the damage caused by a bullets passage through the viscera. A bullet that stays inside doesn't "dump" energy; energy is a mathematical equation and math kills nothing,well, except maybe the odd high school student.
When a bullet exits, its work is done and any remaining "math" is irrelevant unless it hits another target. Some refer to something called "dwell time". Okay, try surgically implanting a bullet/ball into a critter; can't beat THAT for dwell time. And it will kill nothing, zero, nada. Shoot accurately and the lethal damage is done. Don't go looking for the bullet so you can save that energy. Damage kills, not numbers. Once a ball sails through the boiler room the job is done whether or not the ball exits.
I do prefer pass throughs on live targets; but they were never necessary for a clean kill or even a blood trail. In conclusion, don't worry about "wasted energy", "dwell time" or any high sounding hypothesis, just shoot accurately in the correct spot and carry home dinner.
