Justin, I'm not sure you totally appreciate the fuction and performance of a bullet. While a rapidly expanding bullet with minimal penetration may indeed dump a lot of kenetic energy in an animal, the would channel is short and the energy limited to one specific area, as in your example of a punch in the eye. Depending where that energy is dumped, it may indeed disrupt organs but it may also be a temporary disruption. We've all seen animals drop hard from the initial energy dump and then get up and run away apparently unscathed. A deep penetrating bullet that also expands well, dumps energy along the complete length of the wound channel, creating a far more effective use of that kenetic energy, even if all of it is not displaced within the animal. It's this long wound channel and the damage associated with it that makes the TSX and other deep penetrating bullets so effective.

Where you really start to realize the importance of this deep penetration is with larger game like moose or African game. They can soak up a lot of kenetic energy dumped in one location but quickly succuumb to a long wound channel with a wide path of energy dump. Just because a bullet passes through does not mean it doesn't use most of it's energy. Bullets like the TSX experience very rapid expansion at high speed and are designed to use energy and penetrate well over a very wide range of velocity. Most people are shocked to learn that very close range high velocity shots with a TSX typically have far less penetration than mid range shots.

While your punch in the eye may knock someone down....don't coun't on it keeping them down...

Bergers too are a very effective bullet but not for the reasons you are expressing here.
