Obviously the ability to stop any animal depends on its intent to kill you, etc,etc. It also varies with the location and effects of the non-fatal CNS shot you deliver. If we continue to talk about RESULTANT stopping power we are helpless--

But somewhere in there is DG EFFECTIVE STOPPING POWER-- the objective sheer contact force applied( ability to move objects) delivered to the animal. Empirically this should be able to be quantified if the bullets total energy is expended in the object shot.

The reviewer Hall feels the answer lies in the bullet energy acting thru the bullets momentum and tries to validate this thru bullet cavity volumes et al.
bullet energy x momentum!!

My fluids mechanic engineer friend disagrees somewhat since the shot object is penetrated with a certain diameter bullet.
He suggested a empiric formula for DG stopping power might proportionally be--

bullet energy x momentum(mv) x expanded bullet cross sectional area(soft points).

This still doesn't take into effect hydrostatic shock,etc.

Sorry for all the math BS but it is always fun to try to figure out which rifle is the bigger stick--

Hope I didn't bore everyone to tears.
