Fascinating thread. One that makes 24hour so usefull and thought-provoking. FWIW, I've killed deer with a shotgun slug and .35 Whelen on the slow end and a .270 and .30-06 on the fast end and in my experience, there is absolutely no question that a faster bullet will put a deer down faster. I liked MontanaMarine's comment about the huge holes we sometimes find in animals we shoot being much bigger than the expanded bullet. I once shot a pronghorn with a 130 BT out of a .270 Win. at about 40 yards. The exit was literally as big as my fist and I'm quite certain that the bullet didn't expand that much!
