I have not read all the posts yet on this thread, but while working to day I thought of this explanation. We have two ways to express energy .....as measured as foot pounds, Or the other as a vacuum inducing " hydrostatic " shock. Hydrostatic shock relies on an exit hole to in essence " suck " or aspirated vascular tissue into non viability. Hydrostatic shock not only requires full penetration, it need velocity. These two requirements demand both shot placement, adequate barrel length, and cartridge powder capacity.

Foot pounds of energy are only felt by an animal if the projectile does not fully penetrate the beast. Once it fully penetrates the energy is still in the bullet wasted on the impact of wherever the bullet goes and hits next.

Using a heavy bullet with a large meplat helps ensure maximum foot pounds of energy are utilized in the process of shooting into an animal. The larger meplat lowers the sectional density limiting penetration, but the heavier bullet " stores" energy as it is sent down range. This energy will transfer into the beast as the bullet sheds its weight while going through the tissues.Thus reducing the need for precise, shot placement, barrel length . One could also employ a smaller cartridge length.....for faster actions.
Makes this approach perhaps a better compromise in point blank situations.

Just my thoughts.
