No Mercy,
Ah, the pitfalls of reading off of the tail end of the thread.... and then turning to Mr. Webster --- it don' t work in this case.

This thread starts with P.O. Ackleys three main components of " killing power" --- (1) one theory LABELED " Kinetic Energy" -- the nice simple ft. pounds theory advocated by most NA hunters.
(2) another theory LABELED " Momentum" -- the negative results associated with a critter " stopping" a big, heavy, wide bullet as advocated by many DG hunters.
(3) another theory LABELED " Shock" -- the hydrostatic shock you allude to.

Several of the people who were discerning a differenc between " momentum" and " kinetic energy" were talking the theories that were grounded in the start of the thread and the references therein.

While Mr. Webster MAY call Kinetic Energy and Momentum synonyms they are NOT the same if you read the theory, math and philosophy and experiences behind each label.

I' ve followed your stuff -- you' ve got some nice rifles in some real decent calibers and don' t appear to be afraid of the big stuff. Just gotta point out that I think you missed the intro. Your opinion is valued though.
