Shot placement is key, but should some monkey set loose a wrench, I want to make a bigger hole.
...."Shot placement is obviously critical, and our test criteria presume that the shot is placed in the vital area of the body which contains the brain, upper spinal cord, heart and aorta/vena cava. This area runs from just above the eyes to the diaphragm, and is about 4 inches wide.
But, as our experience in Miami amply illustrates, shot placement is only the first part of the equation. Jerry Dove placed his shot perfectly. Bullet performance is critical to translate shot placement into an effective, incapacitating wound. If shot placement was all that mattered, we could arm all Agents with .22’s.
Secondly, perfect shot placement may be difficult to attain in the stress and dynamics of a shooting incident. The larger calibers offer a “margin of error” in that where a smaller bullet may just miss the aorta, for example, the larger one in the same placement will damage it."

Muzzle energy of a 22magnum from a rifle barrel is equal to a 9mm para from a pistol barrel.
Think about that before scoffing at rimfire for self defense.
22mag from a pistol is approximately equal to 32 auto from a pistol, in terms of muzzle energy. I would consider a 22mag revolver to be useful as self defense weapon. I'd have to think about 22LR some more.
