you guys are just old school 45ACP, Col. Cooper, etc. etc. 9mm, 40SW, 45, 44 magnum, not a one is going fast enough to be that much different. Lets say your 45 expands to .55 and your 9 to .45, your still only .1 inch difference and at roughly the same speed. If what ever you shoot pokes thru both sides its about the same. Now just for the sake of argument, lets say a fellow had some of that black talon ammo where a 9mm expanded to .50 and had razor sharp edges, do you believe this would be more damaging than blowing a hole thru both sides with a .45ACP expanded to .50....statistically probably not nor vice versa. Of all the people posting and commenting, those who suggest hitting the target and poking a hole thru it makes more sense that all of this other nonsense.
