Try firing a hot .44 Mag in an indoor range ...
But the funny thing is, that the thing being left out of that equation is lethality, and things like muzzle energy and velocity are only marginally related to lethality. At normal hunting ranges, and the vast bulk of all game animals are taken inside of 100 yards, a 44 mag will kill more efficiently than any normal 30-caliber rifle cartridge.
From Barney Miller:
Ever fired a bazooka?
Yea I have, in 'Nam.
Oh sure, outside!
