OK, you don't know what you're talking about. Size of the round isn't the only thing that matters. It's how much energy a round as and how much it can transfer to the body. That's why, for example, a .357 magnum is more effective than a .44 magnum. The .44 has more total energy but the .357 is more effective against humans. Why? More of the .44's energy leaves the body through the exit wound. Do some homework.
