.45 acp fmj penetration on human targets

Does .45 ball typically go straight through bad guys in a frontal shot situation or does it stay in the body?

Read up on over-penetration.. Webster should have a picture of a .45 fmj....
Of course, you did not mention range so get ready to hear all about the differences.....
And as to straight through, what about bones? they're everywhere.

If you look in the General Discussion subforum, there is a Gunshot thread by Odd Job who is a radiologist.

He has spent a good deal of time providing a very informative presentation on gunshot wounds.

The short answer is that it's very hard to predict what's going to happen when a person is shot.

45 acp

stays better than a 9mm or a 40. The mass, the lower fps and Hydra shocks [hollow points] helps that situation.

I agree to some extent, it depends on a lot of things. Range may be first, shot placement second... Maybe some one should start a poll if all they want is opinions for a general answer,, but the question here is .45 BALL, am I wrong?

Anything else is off topic..........

BTW, good guys have soft tissue too....

Umm, why would you want to shoot a good guy?

I read an article by Chuck Taylor where he said he shot BGs with .45 ball, only a couple penetrated completely but were recovered inside the clothing on the exit. Here is more from him on .45 ball...

"Were I to "play the percentages," or base my opinion on a more narrow examination such as (for example) a review of the files of the law enforcement agencies with which I have been associated or draw from my own personal experiences alone, I could legitimately state that .45 ACP 230 gr. "hardball" fired from a M-1911 Colt auto, is 100% effective!

How? Simple -- in all of the departmental shootings in which it was used, it worked. And because in five of the seven pistol fights in which I have been a participant, I used a .45 with ball ammo -- and it worked. I won all five with my first shot, my opponent collapsing before I could fire again. Five center hits, five one-shot stops, five DOS (dead on the scene).
...

Take a look here.

http://www.thefiringline.com/forums/...d.php?t=214744

People are not a homogeneous medium, so what is hit makes a tremendous difference in how much penetration there will be. In general, all of the typical SD calibers with ball ammunition will penetrate sufficiently in soft tissue to make an exit very likely--if no bones are hit. If bones are hit (and it goes without saying that there are a lot of them in the human body) it's anybody's guess as to what's going to happen from there. Odd Job says it far better than I do and includes pictures and X-Rays to help explain.

I took a 230 gr FMJ once and it entered my body, exited and embedded into the wall intact with minimal deformity.

The range was muzzle contact, I had more pain from powder burns than from bullet wound.

FMJ definitely in my case overpenetrated.

That was intended as a reference to your generalization of .45 ball going through BG's, and to highlight the fact that Good guys get hit by .45 ball too.....

Now that's what I call a first hand observation.

Thank you very much for sharing your experience Mr. Dunn. I know this is not my post, but I for one appreciate you taking the time out to share your experience with us.

Here are penetration figures showing what is expected penetration in soft tissue (no bone). 9mm numbers are included just for fun. Note that both calibers penetrate to similar depths--about 2.3 FEET.

http://www.firearmstactical.com/imag...0US%20M882.jpg

If you're talking any typical defensive handgun caliber & scenario, the penetration of FMJ ammo out of a typical SD caliber is sufficient to fully penetrate a human from any reasonable angle if a bone is not hit. If a bone IS hit, (which is very likely) then there's no way to make a prediction.

buckster mentioned hydra-shok, but the OP said ball.
So, back to the .45 ball.........

From those pics it look's like the .45 just kept going, while the 9 mm took a few breaks and cut out of work early....Thanks for the .45 plug...

It was a simple question, but there is no simple answer..
Better to just let the thread die out with a simple, incomplete answer.

I apologize for jumping on you, I assumed that you were responding to me because you quoted me in your post--I just couldn't quite figure out the basis for your objection.

I'll touch things up to remove anything that might reflect negatively on you.

I wasn't a BG last time I checked, but FMJ will overpenetrate, especially at close ranges, unless it hits major bony structures and loses too much velocity.

I have also seen them pulled from bodies during autopsies, so there are a lot of variable obviously that would have an effect on the performance of a given round at a given time.

It sure as hell hurts though.

.45 ACP has about a 50 50 chance of tumbling, supposedly. If it yawed in the body and tumbled I think it would probably come to rest in the skin of the persons back, but thats just conjecture. I think .45 ball has a tendency to stay in the target more then 9mm for some reason though.

45 fmc penetration...

I witnessed an pair of BG's get shot while fleeing on a motorcycle. The shot was made at about 20 yards by a Marine Sgt. One shot was fired from his 45acp at them while they were picking up speed on their get-away! The shot went in the back of the fellow on the back of the bike and out the chest of the fellow driving it! They went down and were both dead by they time they were approached. One round of GI 45 ammo, 2 VC dead. Worked just fine!!

my dad took two .45acp ball in the center chest from about 6-7 feet in the 50's.

One penetrated all the way through, it was a low shot and it punctured his left lung on the bottom and came out the back. He's very lucky that he got good treatment. Sounds like a scary surgery NOW, let alone 56 years ago.

The second bullet, (was actually the first round fired) stopped on his breast bone.

I have NO idea what he was shot with, possibly RN lead? I don't know what was around back then. But my dad is still kickin' and definitely wiser. He told me "son, if you're getting robbed at gunpoint, and you don't have a gun, keep your mouth shut." sounds like a good plan.

My uncle also got hit with a .45 AD in vietnam, it shattered his femor, he's 2" shorter on one side.

as a side note, the only person in my family to die from a gunshot wound took one .22 lr to the head at about 15'.

Well, besides the fact that there is a Beretta in .45ACP, if you had looked at my post earlier in this thread, you would see that a 9mm FMJ bullet penetrates to an almost identical depth in soft tissue as a .45ACP FMJ bullet when you compare the military loadings of the two calibers.

Thats right, it might even penetrate more if it doesn't yaw.

That's what scares me aboout the .45 and makes me carry "thinner" stuff like .357 Sig/Mag; 7,62x25 (Tokarev) and 9x19mm etc...

JohnKSa, we're bound to have different opinions again.....

But if those reading just base everything on your posted test results and
this;
Quote:

You did say almost right....??

The OP asked if
Quote:
.45 ball typically go straight through
and we both agree that bones change everything,,, so I'm going to go back to the Original Question and answer,,,, YES.....

But, because we have agreed to disagree, I have to quote you again, in the most respectful way, and say that,,,,:::
Quote:

I agree with that 100% .

I'm curious though, can you PM me with any links to a study of .45HP vs 9mm..?

Correct--"almost".

If you look at the scale on the graphs, the 9mm actually penetrates a bit farther in soft tissue than the .45ACP, but really not an appreciable amount.

And also correct--if the bullet hits a bone it's virtually impossible to predict accurately what's going to happen.
