One of the real chewtoys hunters get into is the stopping power of their weapons.

I personally consider it the abiity to stop a attacking charge with a non-CNS shot. If the CNS can be hit routinely we would all be hunting with smallbores

Indeed with enough "STOPPING POWER" the animal should be "shocked" into ceasing the attack thereby sparing the hunter from physical injury.

Intuitively we know that a 458 bullet will have more stopping power than a 22 by virtue of its momentum and contact area.This still may not take into the account other effects of velocity.

Taylor had his "Knock Out" tables--
Is there something better??

One fellow,James Hall, has tried to quantitate this by formula definig a KINETIC PULSE THEORY

Question-
Is your rifle a poorer or better stopper than you think??
