I'm sure most of us are aware that the .357 Magnum (particularly in certain loadings) has a kind of legendary "Manstopper" status. A status which seems to pre-date ballistic gelatin testing, the Strasbourg Goat Test, the M&S data, all the writing on those things, and pretty much all the other subject matter on handgun stopping potential that came after the FBI Miami gunfight.

So, without discussing all that stuff, does anyone know where the legend of the .357 Magnum actually came from? Was it gun rags, ammo companies, actually shootout involving agencies such as the Border Patrol? Something else?
 
I wasn't there so all I know is what I was taught. The .357 mag was the most powerful round when It was introduced to the public. This was a time when most revolver cartridges couldn't penetrate a vehicle, so it became a hit with the law enforcement.
 
Back in the '60s there were certain irrefutable facts:
.45 ACP would stop an adversary with one shot 95% of the time.
.357 Magnum would penetrate an engine block.
.44 Magnum would not only penetrate but knock an engine loose from the mounts.
A hit from a 5.56 round would be instantly fatal regardless of where it hit. Center of mass, shoulder, wrist or ankle; it didn't matter.
 
The reputation of the .357 Magnum was made by actual police shootings in the late 60's through the 80's.
The 125 grain jacketed hollow point got a tremendous reputation for stops, and it was the nation wide standard police issue round for those departments and agencies allowing or issuing the .357.

Numbers and theory are good, but actual shootings tell the tale.
 
I have read the 357 was loaded hotter in 1935, Jeff Cooper wrote he fired some vintage rounds, noticed the difference in the recoil and much harder to extract. I recall reading some of the marketing hype from back then-"We recommend this round only for men with an above average physique" or words to that effect. Bill Jordan wrote that the first time he touched off a .357 "I had a very good sight picture when I closed my eyes." Cars from the 30s to the 50s or so had much more open space in the engine compartment so a bullet had less to penetrate though I have read the lead bullets were on the soft side.
 
The .357 Magnum does indeed deliver a significant amount of energy. It is likely worthy of its reputation. The closest we've got in a standard production semi-auto handgun is 10mm. Note, I don't consider a Desert Eagle a "standard" production firearm. Full disclosure, I am a 10mm enthusiast and while I own no few revolvers, I own none in .357 Mag. .357 Mag is hard to beat in a semi-auto.

That's what I thought. But it seems these days many people favoring a different narrative, have pushed the idea that the status of the .357 Magnum was merely hype and hyperbole rather than actually real world performance.
 
My Dad was San Antonio PD and they carried 357 for the better part of the first half of his career. Late 70s to early 90s. He said the 357 was the gun of choice due to stopping power and it could through move thorough blockades of metal like car doors. As a revolver it was super reliable in any situation. Note that when he initially went through training, the POA was lower belly. They believed the best shot was lower belly due to shock of the body in that region. So chest was not POA. Regardless, the 357 was deemed dangerous to bystanders due to its ability to go through blockades. 45 ACP was considered too much for women, so 40 cal and 9mm became to go to round for people stopping without penetrating through barriers. For transparency, I am a huge fan of 30-06 and 357, so i might have a bit of bias.

If you are thinking the Sanow and Marshall data is accurate, think again. It has been proven they cooked the results to favor their position.

Do you have any link/addition info on them fudging the data? What position were they trying to favor?
I do recall them supporting 32mag FMJ which seems like an odd position to favor.
 
I think the 357 gained popularity as it has decent stopping power and is controllable to shoot. It also has the advantage of being able to shoot 38 special.
When looking at good stopping power rounds. The 41 magnum was developed as a law enforcement round. It isn't as controllable as the 357.
 
The 125 gr. JHP .357 Magnum, out of a 6" barrel, was an absolute stinger in its original service loading.

I read the book and the follow up critiques. An internet search gives many posts regarding the topic.

Modern ballistic theory:
9mm 124gn JHP at 1200fps can stop anybody and do anything.
357mag 125gn SJHP going 1400+ is over rated hype.
Its like “new math”.

Yep. What's interesting is that the proponents of this "new math" are the first to admit that multiple hits are required to reliably stop a threat. Frequently suggesting that faster shooting and more hits are needed, and that shooting until the threat is down is what must be done. Which for a modern 9mm may well mean more hits than a traditional .357 Magnum revolver even holds. Yet the loads are equally effective because of modern bullet technology.

That's some pretty funny logic if the .357's legendary status is based on facts. And if it's not, I'm led to wonder how more LEOs didn't die from running out of ammo in their 6 shot revolvers before the threat was successfully stopped.
 
Apparently the initial advertising was pretty effective - to the point, for example, that the old Dick Tracy comics often featured "Magnums" - so folks who didn't necessarily know anything about guns still knew about the .357 Magnum.

People who did know about guns were probably aware of Major Wesson using an original gun and load to take quite a bit of game as well. Reports were that elk, moose, and grizzly all fell with one shot apiece.

And then, of course, there is the Sanow and Marshall "96%" figure which, regardless of one's feelings/beliefs/whatever, did make a big impression on folks a few decades back.

In 1992 Flagstaff AZ, I shot bull elk broadside with a 180 grainer JSP at 50 yards.Was shooting my 6in GP100. Blew a big hole in him, he ran 20 yards and piled up on an Aspen log. Looking for the bullet, I saw it hit a mule deer and dropped it also 100 yards away 😂
In all seriousness, I've been a fan a shooter and reloader of the 357 for almost 40 years. It's the real deal for self defense, and it ain't no slouch in the hunting field either.
It's hard to beat it.

Back in the day we put MUCH more emphasis on marksmanship. When I first started in law enforcement, our qualification course was the NRA National Police 60 shot course of fire that included 24rds fired at 50yds. We carried our 12 extra rounds in drop box leather cartridge holders as speed strips and speed loaders were new innovations. Not accepted yet by higher ranking police administrators.

My last annual qualification was 30-shots with a G22. Only 2-rounds fired from 25yd line…

Our department issue circa 1978 was Remington 125gr SJHP. The only two incidents I was only remotely involved with were one shot fired, and three shots fired (by officers).
The one shot fired was in a scuffle for the officers gun. Bang-flop, perp declared dead at the scene by coroner. Second was a perp had taken officers revolver, and fired shot at arriving backup officer. Backup fired three shots… first into hood of the patrol car. (Officer had taken cover behind fender). Second struck perp in right leg below the knee, second hit the perps mouth, blowing out 4-front teeth, and taking out 2” of the right mandible and exiting the neck. Perp was incapacitated at scene, transported to nearby hospital and survived. It was my supervisor that was disarmed, and my partner who shot the perp. Perp was a large ex-collegiate football player passing forged checks. Supervisor was 5’5, 145lb heavy smoker…. Range was 60feet.
It was my day off, and I was cutting grass when it went down, 2 blocks away… heard the shots..

My experience is that the .357mags reputation is earned. Not withstanding the hyperbole of busting radiators or penetrating engine blocks, and such…
I’ve taken deer and pigs with various .357loads. Shot placement matters. Only once did I resort to having to speed load. I was accosted by a pack of dogs while collecting evidence after-the-fact on an illegal-baited dove shoot. I shot six time’s taking out 5-dogs, missed (I think- it was a melee!), and reloaded, firing one more shot at fleeing pack. I recovered one bullet that struck a pit bull-mix that hit the chest. He spun around several times biting at his opposite hind quarter before running out of gas… I found the bullet lying on the ground where he bit it out and spit it out… (Winchester 145gr Silver-tip. That box/lot# chronographed at 1,345fps from my M686 -4”).

Though I still have some of the Winchester Hi-Speed 158gr Conical FMJ rounds from when I worked at a municipal P.D., and had a speed strip of the infamous KTW Teflon coated penetrators. I donated them to a police museum…

The 357 Magnum earned it's reputation because it could drive the old hollow points fast enough. With it's power it drove a heavy enough hollow point fast enough to get good expansion and good penetration. It still does it today. It's a fantastic round, but has a lot of recoil.

As for the borderline childish remarks on "new math" and the rest of that ridiculous statement. The reason why officers and soldiers are taught to shoot until the threat is gone is because there are a lot of dead officers and soldiers who taught us that lesson. Does modern 9mm drop people with one good shot? Most of the time, yes. But not always. Does modern 45 drop people with one good shot? Most of the time, yes. But not always. If you train people for years that one or two shots will stop the threat you are setting them up for failure when it doesn't work like that.

Absolutely. Though I think you may have sailed right past my point. Which, just for clarification, would be this: It appears the .357 Magnum didn't need 4 or 5 or 6 or more hits to stop a threat. That seems not to be the case today, with modern service handguns and ammunition. So it would appear the two are far from equal, despite some suggesting so.

This says a lot in itself.
The problem with collecting data around stopping power and cartridge/bullet effectiveness is collecting the data.

Because opinion is part of a equation and it should have nothing to do with it.

All service rounds are pretty equal today as the FBI gel standard is how most ammo is loaded.
