No one is arguing that that higher the sd and the higher the impact velocity the deeper the bullet will go. I think you understand the concept but you don't understand the physics. Kinetic energy is calculated by 0.5mV^2 or 0.5mV*V. Your velocity term is in this equation but so is the mass. That is why energy is the most important part and not just mass and not just velocity. Mass between bullets usually doesn't change a pile for hunting rounds. What does change is velocity and that term is squared. So for every 100ft/s increase you get 10,000 fold increase to energy. So if you are saying velocity is important, then YES you are correct. But energy is what makes velocity important. That's why it is frustrating when you fail to quote energy difference in any of your comparisons.
