Big difference in stopping someone OR something that wants to kill you and you only wanting to kill something. A good center double lung shot will kill anything on the planet, given enough time. It will not kill say a charging grizzly in the time it takes the bear to you. It has been proven many times, heavy , well constructed bullets penetrate deeper making it more probable to get to the CNS or skeleton support system.
If God wanted you to walk and carry things on your back, He would not have invented stirrups and pack saddles
