on stopping power

I have given the self defense situation a great deal of thought.

My take is that it is two totally different situations. In either case, once the guns comes out, its dire enough that if I shoot, its going to be to shoot to kill.

Outside: There would have to be some very overt action to stop. Obviously it depends on what they are armed with (if anything) distance and what's going on. If the person turns away, then there is a hold. they drop the weapon and stop instantly, there is a hold. Throw themselves to the ground there is a hold. If the threat continues I will shoot and I will keep shooting until there is zero question of that person continuing.

Home Defense: If a persons in my house, there will be zero hesitation. They have given up any latitude. There is no way to assess the situation at all as its sudden, no surrounding time to have seen what has lead to it and you have no idea if it’s a multiple threat. Unless there is gross evidence otherwise (see note), I will start shooting as soon as I can sight on then. Shooting will stop only if they are no longer a threat. Even if they are going down the shooting will continue if there is any threat possibility.
note: While unlikely, a child standing there, a woman with a baby in her arms, someone standing there crying and not moving and open hands. I can only conceive of something like that if a door got left unlocked and a distraught person got into the house. My tolerance for anyone in my house that does not belong is razor thin. Simply by being there they have given up any latitude, so the evidence has to be grossly high they are not a threat. Any failure to respond to a command is on the same thin grounds.

I submit that all "defensive cartridges" (those cartridges which include the 9mm para, but less than full powered .44 mag) are under-powered, that is why we are taught to shoot at least twice to center of mass, assess and proceed as necessary.

You obviously do not read or continue to ignore the real world data.

What that real world data says is, from 9mm up to the largest hand gun round (44 magnum), there have been no shoots with a 500 S&W I have seen), there is no such things as a true stopper.

It also makes no difference if you shoot badly and still hit, a 44 magnum has no better results than a 9mm. Conversely, if you shoot well, a 9mm is as effective as a 44 magnum as well as all the calibers in between. Argue all you want, that is what the accumulated data shows.

Its about shot placement, so anything that improves your ability to place a shot well is the way to go. I can shoot my 9mm better as well as faster than my 41 magnum. The 9mm or any other caliber that you can do that with is the right choice, not the biggest round you can fire.

Probably the only one shot stopper is a 20mm or larger cannon.

Shotguns in 12 gauge may serves as well (I have not seen any real data on those). They are ungainly and not easy to deal with safe wise (secure or hide when you are not home sans a safe). Its an option, I am not sure a good one but I leave that to those who choose it and respect that.

So, while I was at one time a carrying of large caliber guns (44 magnum included) I have chosen to keep a modern 9mm high capacity with rail for SD.

As it is effective as anything larger, with a 16 round capacity it allows me to deal with more than a single threat without having to try to deal with a spare magazine.

It is not a guarantee, but it gives you the best odds and that's is the best you can hope for with a gun that is not a true stopper (30-06 also was not a true man stopper, it wounded far ore people than it killed). Until you make such a huge whole or take off large body parts nothing is a sure one shot stop) .

Well said. Nothing will ever replace good shot placement. Shooting well is more important than the ballistics of a specific round.
 
Placement is the most important factor no matter what you shoot.

Yes, but who in the world of SD officiondos doesn't know that already?

What's more relevent, IMO, to this discussion, is how bullets and calibers compare with one other when shot placement is similar. Hits to the torso is the standard comparison, though hits to the upper torso might be a better one.

Now I guess I'll sit back and wait for the ol' " if you hit 'em right, caliber don't matter", "Bubba won't know the difference", etc. ----which emphasizes the theory, enthusiastically embraced by some (no doubt with a straight face), that a 9mm JHP, expanding to .65 caliber, is fully equal to a .45 cal HST JHP that may expand to .90 cal--since, "if you hit 'em right, caliber and bullet don't matter".:rolleyes:

Well...

If you hit them right it doesn't matter. The most commonly used round in the world is 9mm. Americans, and from my personal experience, American civilians are the only people that try and substitute a bullet size for marksmanship. My experience with that is 4 years in the Marines, time over seas, and joint opps with military personal from other countries. It is accepted in the rest of the world that 9mm is more than capable.

Larger calibers create more hydrostatic shock, while smaller calibers like the 9mm have more kinetic energy. The most important thing is finding a gun and caliber that you feel comfortable with and shoot well.
 
I found this to be an interesting point of view - a mortician who does over 8 autopsies per day, year-round. This all relates to bullet performance in real shootings, not gelatin. Regarding handguns, he says if the dead guy has one bullet in him, it's probably a .45 or .40 (a slight edge is given to the .45). If there are multiple bullets in him, it's probably a 9mm or .38.

Sorry if this has been posted before...

Some of his claims don't really hold water.

First of all, in spite of what he initially leads people to believe, he's not a "mortician", coroner or medical examiner, he turned out to be a anthropologist and while he may observe autopsies, it doesn't seem that he actually "does" autopsies. He finally let us in on that little secret about twenty thousand words into the twenty-six thousand word dissertation on the provided link.

In addition, his claim to be involved with an "average of 8.2 autopsies a day" is a strain to one's credibility as that's something like a quarter of the autopsies done in the entire state of Georgia and clearly he's not covering the whole state.

Finally, he admits at one point that he gets "skeletal remains and the ones that are so decomposed that the ME can't do much with them". Hard to see how he's making these detailed wounding analyses on skeletons.

Bottom line is the guy has some opinions and used his somewhat unusual job to validate them even though it turns out, upon closer examination that his job really doesn't provide him with any particularly special insight due to the types of autopsies he admits he observes.

He finally admitted that his assessment of caliber effectiveness was based purely on penetration. You don't need to observe autopsies to know how different types of ammunition in various calibers penetrate.

Care to provide some evidence/authority/citations? Isn't hydrostatic shock directly related to, and caused by, kinetic energy and the efficiency of the transfer of that energy to the target? What is the practical effect of kinetic energy that is not efficiently transferred to the target? What handgun cartridges produce any meaningful hydrostatic shock?
 
How do you know that it's "...dropped hundreds of bad guys in their tracks..."? Do you know how many it hasn't?

The load has been around forever and there is plenty of data on it. No I don't know how many it hasn't but from the data collected on real world shootings, if you do your part it will do its. It was just an example of a load that not going to pass FBI protocol but flat out works in the real world.

However, the discussion is about what to choose and on what bases -- not about making do with what's available.

Mello2u has done an excellent job in post 10 of outlining the bases for making the choice.

I understand we aren't talking about making do with what's available, I was simply stating that while the FBI test protocol is a very good way of comparing ammunition, I'm just saying that just because something doesn't pass the FBI protocol because it won't penetrate a barrier does not mean that its a bad load for a civilian in his ccw weapon.
 
Wow, so much bizarre stuff. Newton, you made a lot of claims, but provided no proof. How about showing where the .22 short passes the FBI protocols? How is it that buckshot gives you a 3-5" buffer? What do you mean it has limited penetration in walls?

Placement is the most important factor no matter what you shoot.

People who talk about shot place as being critical or being king are usually assuming 2 other variables will be met, penetration and trajectory. Shot placement being king works great by itself on paper targets where it is assumed that the hole in the target will have hit the organ directly in line with the hole for a person facing you squarely. Few folks seem to understand that without trajectory and penetration, shot placement is pretty meaningless and that when applied to a 3D objest such as a real person, are why shot placement that looks great on a 2D paper target can turn out to be very poor on a 3D target. A bullet entering the front of the body directly over the heart can miss the heart all together if the shootee is turned far enough.

You hear of "drug crazed" bandits that continue the attack, but you don't find that in the newspapers..............Why.
kraigway, I take it by your comment that you think the problem of 'drug crazed' banits pressing the attack is a lot of hype because that information doesn't make it into the newspapers. You want to know why we hear about it but that it isn't in the papers. There are three very good answers. The first is that these stories do occur fairly frequently somewhere in the country, but not necessarily a lot in any one place. It is a phenomenon witnessed time and time again by cops. However, if the perp isn't shot or isn't killed by the cops, the arrest for the drug charges stays under the radar. If it appears in the news, it appears a perp arrested for drugs who fought with officers and that is about it.

Here is a great example of what you don't find in the papers very much. It actually was featured on COPS. WARNING for language and partial blurry nudity...

Here is another example...
http://books.google.com/books?id=kr...nepage&q=linda a lawrence baton rouge&f=false

Why don't we hear about the drugs more when it takes lots of rounds to bring down a suspect? The shooting often does make the papers, but the toxicology screening doesn't get completed until several days after the event and when the story is no longer newsworthy.

Here is a related thread from TFL. Last, not all determined bad guys are necessarily drug crazed but still take lots of hits.

Ah, but the point is that you have no idea how well it works in the real world. That is sort of the point. The .22 lr is reported to have killed more people than any other cartridge, but nobody knows how many shots were fired to accomplish this and how many people survived.

For self defense, even a melonballer will do its part if you do yours.

@fiddle I apologize, it was late I was tired. I used the wrong terminology.

What I was meaning was the bigger & slower rounds such as the .45 carry more momentum, while a smaller round such as the 9mm carry more kinetic energy.

Shot placement is still king in my belief and I disagree that it only translate well to 2D targets. Most of my combat experience is with rifles but a 5.56 to the chest will kill you much faster than a 7.62(x39 or 54) to the shoulder. The ability to take more well aimed shots in a shorter amount of time due to a smaller rounds lowered recoil is also a plus to me.

Then please supply the data and cite the source. A direct statement like, "...dropped hundreds of bad guys in their tracks..." needs to be supported with evidence. And since it's your contention, it's your responsibility to supply the evidence.
 
one of my acquaintances is an er surgeon in chicago....he once said of the people that came in with gunshots that the guys who made it to hospital with gunshots from a 9mm or a 38 or other lesser rounds had a decent chance of survival......

he said that the people that made it to hospital with 44mag and 45 and 12ga rounds in them usually never survived the emergency surgery......
 
If you hit them right it doesn't matter. The most commonly used round in the world is 9mm. Americans, and from my personal experience, American civilians are the only people that try and substitute a bullet size for marksmanship.

Does it take a Rhodes Scholar to understand the basic principle that "hitting them right" with inferior calibers reduces the target area and requires more precision?

To suggest that American shooters prefer an American cartridge like the .45 or .40 caliber because they want to substitute bullet size for marksmanship, is an insult to many shooters on this forum, not to mention many hundreds of thousands throughout the rest of the country.

I have no doubt that the average shooter who shoots .45 or .40 caliber is more proficient with the 9mm, as well, than the average shooter of 9mm only.

The .44Mag is clearly in a different category from other typical self-defense/service pistol cartridges, and the survival rate for long gun injuries is about 20%, vs. 80% for a typical handgun wound.

That said, your acquaintance's comments about the 45ACP are somewhat surprising. It seems far more common for trauma surgeons to make a statement to the effect that handgun wounds from the typical typical self-defense/service pistol cartridges all look very similar in terms of the damage done.
 
Shot placement is still king in my belief and I disagree that it only translate well to 2D targets.

As I said, shot placement is nothing without trajectory and penetration.

You have probably heard that one fail to stop alternate target is the hips. The claim is that if you shoot them there, the hip will break and mobility will be lost. The fellow in this report was shot multiple times in the pelvic area. Due to issues of trajectory and penetration, only one shot managed to damage the pelvis. For example, several shots passed through the buttocks and exited the body, but because of the trajectory, passed by the pelvis through the soft tissue.

One shot entered just right of center about 3" below the neck. This is great shot placement. Had the shot been a straight on and had sufficient penetration, the spinal column should have been damaged, but it wasn't. Trajectory did not have the bullet continuing straight back to the vertebrae.

Linda Lawrence was the first female Baton Rouge officer killed in the line of duty. She was killed with her own gun by James Mullery. During the fight, Mullary was shot several times. Two were square in the chest and a third shot completely through the head.

All of these shots should have been fatal. The head shot should have at least incapacitated Mullery with traumic brain damage. While the head shot had good placement and had good penetration (over penetration, actually), the trajory did not take the bullet through either hemisphere. The bullet bisected the brain between the hemispheres.

http://books.google.com/books?id=kr...nepage&q=linda a lawrence baton rouge&f=false

In another example, during the Tyler gun battle on the square by the courthouse, Mark Wilson engaged David Hernandez Arroyo Sr. with his pistol. Wilson's first shot his Arroyo in the back. When Arroyo turned to face Wilson, he was shot several times in the chest by Wilson.

While Wilson's shots on Arroyo were well enough placed and with good trajectory, but Arroyo was barely phased. The problem was due to a lack of penetration. Arroyo was wearing body armor and so all of the shots but one were stopped by the armor. The shot that did penetrate hit just below the vest and the trajectory of the round did not have it passing through any critical structures.
 
One more factor to mull over: over-penetration. If I shoot hog with a .44mag Buffalo Bore round and it goes through the beast with no expansion exiting it at 500fps, who cares? The worst it can do it injure another hog maybe.

If I shoot a perp with the same gun, the bullet would probably have an even higher exit velocity and I could kill the kid in the apartment next door.

So, for home defense, a 9mm or even 380 that expands FAST makes more sense than a full power magnum. I don't like the 22 or 25 for such duty as I'd invariably try to shoot the perp 10 times like the Mossad does and even 1 stray is too much. You are accountable for every round you fire.
 
The .44Mag is clearly in a different category from other typical self-defense/service pistol cartridges, and the survival rate for long gun injuries is about 20%, vs. 80% for a typical handgun wound.

It's always over penetrated, and was never as effective on human targets as the .357 or even .45 with better ammo that expanded well.

On larger 4 legged critters, where big bore penetration is critical, it surpasses lesser cartridges. Animals, like large hogs, aren't the same as people. The penetration in relation to expansion requirements aren't necessarily the same.
 
True and, believe it or not, the question of "9 vs 45 for deer" comes up on hunting forums every once in a while. The hunters that have actually used both on deer and larger game tend to agree that he 9 actually works better overall because it penetrates more readily... usually. But, again, shot placement and the quality of the ammo used are huge factors. Also, every one of them would rather have used a 10 or 45 super on the beasts instead (or 357 sig even).

But, the argument of "what round is best" will rage on forever I guess. I can't or won't post links to other forums so you'll have to do your own research I am afraid.
 
Kraigwy...that says it all...good post, your background in LE is obvious and to the point...well said, and thanks for your service. Rod....

"Stopping power..............DRT..........?????

Forget the FBI, forget shooting bluejeans, jello, and dry wall.

Look at reality. All you have to do is read the news. Seldom does ANY handgun kill the shootee right away. They crawl off, found down the street, at the hospital, in the get away car...........sure they may die, but not right away.

What does happen, they stop what they are doing. They normally run, give up, try to find help, what ever they normally stop the attack.

You hear of "drug crazed" bandits that continue the attack, but you don't find that in the newspapers..............Why.

Because its rarer then hens teeth. Except may in the Philippines that led to the adoption of the 1911. That's in the history books, not in the news.

I've been to a lot of autopsies, I noticed no two bullets do the same thing, even the same bullet out of the same gun. But they almost always stop the bandit from doing what he was doing, whether its a 22 or 44.

Instead of reading and putting faith in this and that study, look at the news paper. Read about every shooting you can and see what really happens.

I'm not a big fan of studies. I remember in the late 70s reading that a FMJ 9mm has more stopping power then a FMJ 45, because of the starting and ending KE. Since the 9mm lost more velocity passing through the medium, it left its energy in the target.

That was the last study I ever really read. It doesn't take a rocket scientist to see it was flawed.

What none of these test and studies take into account is the nervous system. The exception to that was the Thompson-LaGrand test, or P.O. Ackley's donkey shooting.

Read the newspapers, see what the shootee (dude that's shot) does after he's shot. Again seldom is he DRT, seldom does he continue his evil deeds."

"Seldom" is not the same as "never." I don't think it's necessarily the best idea to plan on your incident, if it happens, not being one of the "seldom" ones.

And see this thread for a discussion of a recent incident in which stopping the bad guy did take some doing.
