But isn' t shooting really just pushing, only faster? Bow string " pushes" the arrow shaft, right? Rapidly expanding gases " push" a bullet or slug, right?

I' m only trying to apply common sense, of which my wife says I have very little

It just makes sense to me that if it takes less pressure to " push" a COI head through hide than a chisel tip head, why should that change if you are " pushing" faster? Why would the " pushing" force suddenly make a difference that allows the chisel tip to penetrate better?

Properly place, on a whitetail, I don' t think it makes a difference, both heads will do the job. Apparently according to Dr. Ashton' s real world testing, shooting a cape buffalo with both styles, one head clearly comes out the winner.
