Some people over estimate any cartridges ability. "If it goes bang, dead deer!" Until bambi runs off. Then they can't believe it.
It's usually the other way around. Guy whacks a few deer with a .30-06 and sees them run 50 yards before they fall. He reasons that if they run 50 yards after taking one through the lungs from a .30-06 they'll go at least twice as far with a .243. Nothing could be further from the truth.
