Oh trust me, I know. I mean, a round's power has as much if not more to do with it's cartridge and powder load than it's caliber. After all, a NATO 5.56mm has almost the same caliber as a .22 long rifle rimfire. But they are definitely not the same :P<br/><br/>I mean, impact would definitely be more appropriate than penetrating, and would have less chances of poking holes in our fancy spaceship at that :3
