zrex,
Choose the parts you like and ignore the rest if you so choose, I stand by parts of the same post you chose not to address....
"Killing power" has many components: shock, energy, penetration, expansion, "momentum" (per Ackley), and TKO. Anyone who picks just one aspect of the overall equation and chooses to pretend the others do not exist, exposes his ignorance of the equation as a whole, IMHO.
and
"....deer kill pretty easily, so attempting to frame the entire discussion in terms of merely "dumping deer" is a pretty weak benchmark right from the get go...."
BTW, the bullet on the far right is "only" doing 2700 fps so apparently did NOT need hypervelocity to function well....
Good luck with your deer hunting.
