it's physics! It takes energy to move the bullet thru the air before impact, and as well after impact. You hit something out there, and it absorbs certain amounts of energy, but the bullet goes all the way thru; thus retaining certain amounts of energy to propell it even further. But if the bullet fails to exit the target it impacts; it then expends all retained energy (thru flight) into the object it hits. Most ballistic folks say it takes around 35% of the energy at the muzzel to propell the bullet, and and it will expend another 35% at impact with the rest carrying it on thru the flight. But if the bullet fails to exit, you then expend the remaining 65% into the target. I might add here that many folks say the number is closer to 40%, while others use a 33% for shorter ranges (300 yards or less). I think the 1/3 number is flawed as it violates one of the laws of physics. In this particular case the bullet struck two massive bone structures, which probably aborbed more energy than if it had been a lung shot. But it still probably 20 to 25% of the energy it had when it first impacted on exit. Probably about 1500 to 1600ft. lb. of expeneded energy.

I think that the main thing with a bullet going faster and exiting that is benifitial is the hydostatic shock. the displacment of fluid/tissue is going to be greater if the bullet is going faster. If you drop a bowling ball into water from 3 feet and then another from 5 feet, which makes the bigger splash? that splash causes tissue damage. maybe my logic is flawed but I have lots of time for learning.
one added benifit of pass throughs is a better blood trail if the game doesnt drop in its tracks.
Sorry, kinda off topic. I still think that the Ultra is better at any range. Barrels can always be replaced.
