10 year stopping power study

10 year study of stopping power based on actual shootings, eye opener to say the least.
The Best Handgun Caliber - A Real World Study - YouTube

The results of the Ellifritz study mirror those se en in shooting victims who arrive in the ER.
The fact is, a .22LR will kill someone dead as a hammer at the same "rate" as a 9mm. The truth is that the .22LR is the "baseline" in terms of "what it takes to put a human down....and yet, the larger calibers do not proceed to being more effective in a linear manner.
It comes down to penetration factor. The .22LF has a PF slightly greater than the 9mm, and about 2X that of the .45 auto. Penetration is the key...the ability of a bullet to punch DEEP and put holes in and through key structures.
"Energy" per se has no practical bearing on so-called "stopping power." A manual stab to the chest with a 6" stiletto will likely cause lung collapse and rapid incapacitation - VERY LITTLE "energy" there!
Today we have innumerable videos on Youtube showing us how people react in shooting situations and to being shot. We have videos such as the Reason shooting, and the RFK shooting that validate the efficacy of the lowly .22LR, yet still the internet is mired in dogma.
 
Man Stopping Bullets

How many times have we all heard "shot placement" is the most important component of marksmanship pertaining to hunting? A zillion? Never doubted it and it's what this is all about.

I served on the jury of a capital murder trial some years ago. The victim was shot with a .380 ACP. He was thirty, 225 pounds, six foot three, and in good shape. One shot; he did not make it to the hospital. The projectile traveled the length of his left lung due to an odd angle - he was shot as he was getting off a couch and leaning forward. As a consequence I certainly respect the .380 ACP.

Get a kick out of one of my hunting buds who always poo poos my "favorite" handgun caliber of .38 Special. He claims "it doesn't hit hard enough." He's a friend but none too knowledgeable about firearms. He carries a 9mm and feels superior - and I let him.

Many, many years when I was playing cop, an outlaw biker took 11 rounds from a 9mm (JHP's) after fatally shooting a fellow officer. He was still alive when he was strapped to the gurney for transport. He died enroute to hospital. Shortly thereafter I was given permission to carry a S&W revolver in .45 Colt (this was back in the days when most cops carried revolvers), me thinking that was the complete answer to stopping the bad guys. Point being, shot placement is important just about always. Some guys are just plain hard to kill quickly. If the bad guy happens to be on drugs it changes things. Variables that you cannot possibly account for will often dictate the outcome of a deadly encounter. I still believe, however, that a big, slower bullet is better than a fast, little bullet. Nothing scientific, it just seems to me to be intuitively correct. But, I shoot Sharps rifles, so maybe I'm just into big lead.

Most of the “gun violence” I responded to during my LE career was suicides. If firearms weren’t available to them I believe they would have found another way.

Agree. I saw a fair number of hangings, intentional overdoses and drownings. Never saw a wrist slitting that was successful although I'm sure that is possible.
 
It is hard for some people to drop their intuitive feelings and discard incorrect old lore. Yes you, Mr. .45 Cal.
Terminal ballistics studies are showing that velocity over 2,200 fps causes serious damage even with small projectiles. With less velocity shot placement and adequate penetration quickly become paramount.
Pistol calibers are surprisingly similar in lethality.
This understanding of terminal ballistics is a big part of the trend away from heavy revolvers to 10mm pistols in big bear country.
The wild card is the motivation, mental state, adrenalin, drug use, etc. of the target.

2200 fps? Maybe for home defense from a .30 or .223 carbine. (Speer claims 1990 fps for 110 grain, and 3220 fps for 55 grain Gold Dots out of 18" and 22" barrels.) But not from a concealable pistol.

Longer barrel length = more propellant burned = more velocity. Using the same .357 125 grain GDs a 7.5 inch barrel SA revolver supposedly delivers 1307 fps and a 16.5" 1894 1987 fps.

BBI tested 3 loads in a .25 Jetfire 765 -- 800 fps
4 loads in a 32 Tomcat 774 -- 1000 fps
7 loads in a .380 LCP 796 -- 1054 fps
5 loads in a .38 Spl 642 847 -- 940 fps
10 loads in a 3" 9x19 933 -- 1389 fps
8 loads in a 3" .357 1191 -- 1313 fps
(4" 9x19 and .357s were constantly ca. 150 fps higher than a 3," so a 2" would be less by up to a commensurate amount.)
11 loads in a 4" .40 989 -- 1336 fps
10 loads in a 3.75" .45 auto 716 -- 1054 fps
(Those are the smallest .40 and .45s they tested.)

I carry a .357, GDSBs are supposed to deliver 990 fps from 2". One thing about a .45, it's always at least .451" in diameter. Some of the light bullets scoot, and those that travel at 750 fps weigh a lot.

Plus suicide is a mental health issue, not a criminal one or one that gun control will affect
Shhh, they will start banning tall-- meaning anything above ground-- buildings, bridges, scissors, kitchen knives, razor blades, lakes, rivers, ponds...

I gave a brief scan to the OP and the alleged "study". Back in the last century I spent years studying homicide rates and the most depressing pat of my study was discovering just how many "peer reviewed scientific studies" were deeply flawed to the point of uselessness.

Rather than beat the dead horse more, I'll just repeat a principle from the first day of inferential statistics class: "correlation is not causation". Come to think of it, that was also mentioned in Logic in a more seemly form: "the crowing rooster doesn't cause the sun to rise".
 
....the most depressing part of my study was discovering just how many "peer reviewed scientific studies" were deeply flawed to the point of uselessness...

It isn't just firearm related studies. It's everywhere-- in my admittedly limited experience. Mom and dad said the schools I went to were "second-rate," but they were far better than the public schools around me today. Ones that rank in the top 10% of the state.

A publicly financed 13-year babysitting service is what they have to offer, not an education on how to reason or find unbiased information.

Colleges seem to be as bad, a 4 to 6 year course on the right words to say without any understanding whatsoever of those word's meanings or implications.

Sheese, I'm not "old" enough to be an "old fogey" but here I am.

I had a friend who was a Korean war vet. He also swore by the 1911. Apparently 45 ACP will knock a man off his feet and send him flying backwards. Couldn't convince him otherwise because he'd seen it happen...

It will definitely spin them around. Another aquaintence had just returned home from a long rainy day of rabbit hunting. He sleepwalked his teenaged son into the house and got him onto the couch. He had just wiped down his shotgun and was sitting in his kitchen with the lights off when the door was kicked in. A man took two steps into the house when my friend shot him with the .45 1911 still on his hip. It spun the man around but he was able to run out the door and escape. Later the police seemed unsure that the man had been hit....my friend pointed up and said, "that aint ketchup on the ceiling". His son slept through the shooting and only woke up when the police arrived. The perp survived, pulled 18 years, and was later killed in Patterson, NJ.

you're wrong. All three of my kids graduated college -daughter is a a physical therapist helping old folks recover from strokes, oldest son a senior project manager building robotic surgical suites, youngest son runs a high tech global project team, all make 6 figures a year, and would never have the jobs without the degrees.
Education matters, at every level.
 
Education matters, it's true.
But.
The buyer must beware. There are too many worthless classes and even majors being actively promoted by higher education.

One of my kids was not able to support herself very well with her 'save the world' Bachler's Degree. I asked her if she was finally going to listen to my counsel. She started to argue at first saying all these school counselors recommended so-and-so. When asked how that was working out for her, she had the brains to shut up and finally listen. I explained that to save others she had to save herself first.
Her Master's has actually made her employable.
 
“When I was a boy of fourteen, my father was so ignorant I could hardly stand to have the old man around. But when I got to be twenty-one, I was astonished at how much he had learned in seven years.” Mark Twain
 
I am convinced that caliber is the least important factor when it comes evaluating a handguns ability to stop an attack by humans.

Animals are a different matter.

My thoughts exactly. People know what just happened and don’t want it to happen some more. They also are self-aware enough to try to get to a hospital.
