Thanks for the info guys. At close range, I think a .177 pellet rifle does more damage than a 22 short. I know this isnt a very scientific example, but my local news station showed the comparitive power one day. They set up several coke cans (unopened) and shot them with a .22. The .22 went through the cans, leaving an
'icepick' type wound. Then they shot the cokes with a pellet rifle. The pellet went it, and then exploded out the other side of the can.
