Agree!

SD x Velocity would seem to equate with penetration.
Thus the plywood tests of bullets with similar SD's and velocities would seem too give equal penetration and equal effectiveness on game.This should apply in a perfect world if all shots are exactly identical placed in critical areas with identical bullets.

I'm no engineer but--

STOPPING POWER would seem to be the empiric relationship of "enough" energy work delivered thru a specific bullet contact area achieving a desired amount of penetration.More energy work done thru a larger contact area while still achieving a desired depth of penetration= greater stopping effect!!.

Empirically--Better Stopping power would come from larger diameter bullets penetrating a desired distance.With the same energy---Too small a diameter high SD bullet equals good penetration but not enough shock effect. Too much bullet area at the same energy and penetration would decrease signifigantly with risk to life and limb with DG.

You gotta have BOTH "shock" and penetration for "stopping power" for DG.

Somewhere, seems someone could/has already devised a formula
for this.Does Taylor's or anyone elses do this?

Anyone please correct me if I am confused or off base.
