Information Sources
All figures listed under the Marshall & Sanow's Latest Ratings are sourced from the references listed below. Because the database of actual shootings, and the number of new ammunition & bullets being released is continually increasing, a situation occurs where different sources list conflicting figures for the same calibre/load combination. When this occurs, I have used the figures from the most recently dated publication. Many thanks to the following publications, people, and organisations for the actual figures, and much of the information about handgun stopping power provided by this site:

- FBI Wound Ballistic Evaluation
- Federal Cartridges (Product info and brochures)
- Guns & Ammo Magazine (September 1992)
- Guns & Ammo Magazine (October 1992)
- Guns & Ammo 1994 Annual for the Strasbourg Test Information
- Handguns Magazine (February 1995)
- Handguns Magazine (December 1995)
- Hornady 1995 Catalog (Pictures)
- Handgun Stopping Power (Marshalll & Sanow) for most of the figures and background information
- Larry Ellision for pointing out errors, for constructive criticism, and useful suggestions.
- Magsafe Ammo Company (Product info and brochures)
- Marshalll & Sanow for all their fantastic work, and regular updates
- Rick Dixon (D&D Omega Star Bullets) for figures, photo's, bullets and other interesting information
- Street Stoppers (also by Marshall & Sanow)
- Criteria for Determining a Bullets Stopping Power
- [Marshall and Sanow, pages 43-45]
The bullet must strike the torso (excluding the head and neck) of a person. It seems obvious that a bullet that strikes a hand, leg, arm or foot, will almost certainly never bring about instantaneous incapacitation. Secondly, a successful one-shot stop occurring in the neck or head owes its success to shot placement, rather than calibre or bullet design.

Multiple hits have to be discarded. We are interested in the effect of a single bullet. Again it is obvious that multiple shots will be more effective, however it is impossible to determine some measure of bullet performance based on multiple shots.

Figures are provided (by Marshall & Sanow) only when a minimum of five instances of shooting with a particular load/calibre combination have occurred. In addition, some of the following information must have been available: police reports, evidence technician reports, homicide reports, autopsy results, and photos (among other things). In addition, the actual recovered bullets or photographs of the bullets must have been available for examination.

Marshall & Sanow have developed a method of estimating a bullets performance based on correlating the results of the performance of new bullets fired into 10% ballistic gelatine with the results of bullets with known performance on the street, also fired into 10% ballistic gelatine. (Read the book - you'll find out that their method of estimating is the most thorough and likely to represent reality as you could possible get). All figures that are estimated are marked with a "*". Reality shows that frequently the estimated figure turns out to be a little below the actual figure when it becomes available.

Validity of the Bullet Effectiveness Estimation Theory
[Marshall and Sanow, pages 187-196]
Marshall and Sanow make use of four areas of a bullets performance in 10% ballistic gelatine to predict a bullets effectiveness. In each case the bullets known performance on the street is compared to the performance in the ballistic gelatine. The results allow a new bullets street effectiveness to be estimated based on its performance in ballistic gelatine. The correlation coefficients for each area of bullet performance in ballistic gelatine with actual street results are:

Penetration. The correlation coefficient for penetration is -0.37
Recovered bullet diameter. The correlation coefficient is 0.82 for bullets under 1300 fps, and 0.68 for bullets over 1300 fps.
Permanent crush cavity volume. The correlation coefficient is 0.87 for bullets under 1300 fps, and 0.60 for bullets over 1300 fps.
Temporary crush cavity volume. The correlation coefficient is 0.80.
Of course, the closer each correlation coefficient is to 1.0, the more accurate the prediction. In practise, Marshall and Sanow's method has shown itself to be very accurate, and has become the standard by which many bullet manufacturers and knowledgeable publications compare and estimate new bullets performance.

Lots of those loads aren't being made anymore, and there are new ones out that work better and have the advantage of a few decades of JHP development, deign, and use to build off of.

Neat to have all that ballistic data in one place though.

 

[Shadow 7D]

M&S study has been beat to death, and you get into caliber wars, questions of methodology but to really sum it up, and I believe that it is even in the full study somewhere, it comes to shot placement and training, so just packing the x or whatever caliber that is listed by them as "best man-stopper" never mind that bullet design has drastically changed in the 20+ years since this came out, doesn't guarantee a damn thing.

So to sum it up
Practice, practice, and practice,
OH and get some quality training, whether from a big name or just some "guy" at the local range, go and learn, because it will and does make all the difference.

It's just a chart, some may find it useful. It's not a debate, or question, just a chart that may be of interest to some, no need to make it into something it's not. We have many new shooters that may be interested in basic stats. Some don't even know some of these calibers exist, it's information not a recommendation on anything.

 

[Yo Mama]

It's just not complete. You don't have barrel length on most of the calibers.

Also, HANDGUNS DON'T HAVE STOPPING POWER!

 

[KBintheSLC]

Interesting to see that some of the rifle rounds received 100% effectiveness ratings. I assume that is 100% in the small pool of cases reviewed with that ammo. It would be hard to believe that any small arms ammo could produce 100% effectiveness all of the time.

Thanks for posting.

 

[macadore]

What about the 9mm Makarov?

 

[gym]

There is a link at the bottom with more data that wouldn't fit "amount of words was over limit", you can cut and paste it ,http://www.familyfriendsfirearms.com/Stopping Power Statistics.htm, and read the entire thing including 22's etc.

 

[Vonderek]

It's based on actual shootings, not under laboratory conditions.

 

[Yo Mama]

^ Ahh, that makes sense.

 

[LeonCarr]

Handguns don't have stopping power?

I will not volunteer to test that theory .

Just my .02,

Now all we need to accompany that chart are the questionnaires from which these statistics are derived from. You do have those, don't you?

I agree...and actually had kind of forgotten about it. It's always interesting to revisit and I'm sure folks who haven't seen it may appreciate the post.

Are good observations and, if I recall correctly, the true "issues" with the findings. They aren't scientific. There is no true statistical data. The information was compiled on actual events with so many variables it would make your head spin, so the information derived has to be taken with a grain of salt.

Even if we argue for Active Research it still won't hold water.

I don't mean to start a debate - we did that dance when the "study" first came out - just wanted to shed some light on the validity.

Thanks again,
DFW1911

 

[Comanche180]

Except for rifle calibers I didn't see any 100%. So pull the trigger twice. What's the problem?

 

[macadore]

Now all we need to accompany that chart are the questionnaires from which these statistics are derived from. You do have those, don't you?

The only way to run a classical experimental design to prove cause and effect would be to randomly select people and shoot them with the different calibers and different barrel lengths. Then we could actually “prove” which calibers and barrel lengths had the best “stoping power”. Until then, this is the best we have.

 

[HammerheadSSN663]

A well placed brick has 100% stopping power as well.

 

[RyanM]

Not this crap again.

The M&S study only included instances where a person was shot a single time. If someone was shot once and fell over or ran away or whatever, it counts as a "stop." If shot only once, and they kept attacking, it counts as a "failure to stop."

Shot twice and fell over dead, not counted. Shot twice and kept going, not counted. The problems with this sort of methodology are numerous and obvious. For one thing, it skews the percents way higher than they should be, because the main two reasons for only shooting someone once are either the first shot stopped them, or because you're such a terrible shot that only one hit.

Then there are also a bunch of other factors that will have nothing to do with the ammo itself. If you took all the people in the world that own 9mms, and had the ones who CCW with Speer Gold Dot compete against the ones who CCW with cheapo Winchester white box JHPs, who would probably shoot more accurately? Would that accuracy have anything to do with the ammo? Shot placement is key, and people who get "premium" ammo, just on average, practice more than people who get the cheap stuff. On average, it's not going to apply to everyone, because I just know someone's going to say something about that.

The practice difference will apply across calibers, too. In reality, 9mm FMJ makes the exact same size hole as .380 FMJ. Yet 9mm FMJ has a higher "one shot stop" percentage. Why? Because on average, people who carry a "service caliber" practice more than those who carry a "minor" caliber. There's also ergonomics and other factors, too. A 9mm is more likely to be a full size or semi-compact pistol, a .380 is more likely to be a harder-to-shoot-accurately pocket gun.

End result: you can't tell squat from the M&S "one shot stop" data. Trying to draw conclusions from it is going to be an exercise in futility.

 

[MikePGS]

Call me cynical but I refuse to believe statistics generated from information that is super secret.

 

[rfwobbly]

A lot of the ammo is listed with an asterisk (*) at the end of the line, but I do not see what that denotes. Did I miss it? My wife says I'm blind.

?

 

[22-rimfire]

I'm skeptical a lot of the information presented, but it's fun to go over it. Not worth copying and saving for me.

 

[Shadow 7D]

I thought that the info was made available, but most of it was from police reports and autopsy reports, it's interesting, but unfortunately the repeatability is not there, add to this the baltisticians reliance on gel, and you have a wonderful time, personally this is a topic best avoided, or discussed over a few beers with copious body armor.

If you look at what is available and what works, I think that gel can give you an idea of what HP expands well, but still it's lacking, I would like to see somebody repeat the army wounding dynamics, but how many pig farmers will let you shoot up their herd

 

[NG VI]

Wait Georgia Arms? That seems a LOT newer than the last M&S study I saw, what is going on here?

 

[Sunray]

"...Also, HANDGUNS DON'T HAVE STOPPING POWER..." Shut off your caps lock. In any case, handgun cartridges don't have reliable stopping power and either does a rifle. Far too many variables.

 

[NG VI]

Gotta admit though, I do like going over the "data", it's interesting, and the anecdotes they include are pretty interesting as well. Often pretty sad, especially the failures, but still worth a read.
