Why does this matter?
A 168gr projectile moving at 2300+ fps should kill just about anything you shoot at.
That being said if I wanted to produce a lot of shock in a target, and generally violent internal wounding my bullet of choice would be a Hornady 150gr .308 SST. It will either not leave an exit wound or it will be a large dramatic exit wound.
If that bullet can can go into a target and go from 2300fps to stationary before reaching the other side, All of the energy that it carried is transferred to the target.
