An Alternate Look at Handgun Stopping Power

The data for this was taken from:
Greg Ellifritz is the full time firearms and defensive tactics training officer for a central Ohio police department.He holds instructor or master instructor certifications in more than 75 different weapon systems, defensive tactics programs and police specialty areas. Greg has a master's degree in Public Policy and Management and is an instructor for both the Ohio Peace Officer's Training Academy and the Tactical Defense Institute.

 Using the .22 for Self Defense 

It is a compilation of stopping power results from every shooting he could find. He talked to the participants of gunfights, read police reports, attended autopsies, and scoured the newspapers, magazines, and Internet for any reliable accounts of what happened to the human body when it was shot. Suggested reading is: Handgun Stopping Power: The Definitive Study by  Evan P. Marshall 


Greg Ellifritz, is assuming the original target here is the head or torso and there seems to be no attempt to claim the head hit is the brain / medulla oblongata and the torso hit is the heart or lungs. 


Obviously, this represents shooters who stop shooting before the aggressor is incapacitated or independent shots. If you have to shoot an intruder, many recommend a controlled pair of rounds. My rule for self defense against an aggressor, is accept and expect to the rule of three: three yards, three seconds, and three shots for a successful self defense. 


Greg Ellifritz says, " I reported the data I have, but I really don't believe that a .32 ACP incapacitates people at a higher rate than the .45 ACP!"  
While that is a conservative statement that is more popular, it does not explain the data. Given what I know about pain, a sudden large trauma leads to a huge dump of endorphins, of which enkephlin is the main one. The smaller the trauma, the more likely they will feel the pain sooner. 
If you think about it, knowing you were shot by a .45 is certainly not going to feel more like getting shot than being shot with a .22, which is the necessary converse of that logic.People who feel no pain will keep coming at you, even if they have a mortal wound.

I have an example:In the 1986 FBI Miami shootout, Platt, who killed two and wounded two, was killed with the first shot, from a 9mm through his right arm, his lung, and stopping next to his heart. AFTER THAT, he took 11 more shots/wounds.While the mortal wound was taking effect, he fired one handed with his left hand emptying his Mini-14 [10 shots?] and five rounds from his shotgun.

ARROW BALLISTICS

 A 650 grain arrow delivers 54.9 ft./lbs from a 70 pound bow. 

An 800 grain arrow at 300 fps would deliver 160 ft./lbs.

Far less has been used to kill 500 pound bears. 

HAMMER BALLISTICS

A 4 pound dead blow hammer in an overhead swing 
of 57 fps/39 mph would deliver 202 ft./lbs.
