.. full metal jacket bullets that deposit the least amount of energy in an animal are the slowest killing bullets.
is braining elephants with solids less effective[slower killers] than same calibre expanding mono-metals
that can also adequately reach the brain?
A 257 weatherby with a 100 grain bullet that enters a deer sized critter at 3000 fps and doesn't exit uses all of its energy
in the animal.
So the question is was it the speed that did the work or was it the energy???
The material bullet did the work and spent non-substance kinetic energy in the process.
( the bullet gained that energy because 'work' was done on it by a charge of propellant)
