I posed the question of "Foot pounds of Energy" some years ago and "Mule Deer's" response was elegant in it's simplicity,

to paraphrase,

"Animals die, not from foot pounds of energy but from broken body parts"

Another way to say it, place a decent bullet properly and things go well enough.

"Camping places fix themselves in your mind as if you had spent long periods of your life in them.
You will remember a curve of your wagon track in the grass of the plain like the features of a friend."
