FMJ vs HP
I recently posted a thread asking if .38 special +P FMJ with a bit of a flat nose, would be an acceptable self defense round. In that thread I realized that .38 specials or 9mm's or .40's or whatever would be best for self defense as a hollow point of some sort. Otherwise they will just zip right through the bad guy giving him more of a scare, than actually doing enough serious damage to *shock* and *STOP* the threat. I also said that .45's would probably not need to be hollow points and that FMJ .45's would be fine considering they make a big enough hole on their own.
After watching this video, I realize that if that officer had been shot with HP .45's instead of FMJ's his injuries may have been alot worse, and that just might have been enough to change the outcome of the fight. Thats just something to think about |

Muzzle velocity is highest right when the bullet leaves the barrel - it starts to deccelerate from that point on.
having said that... who knows what that bullet would have done given the same angle but lower velocity. who id to say that a hollow point would have done more damage? That bullet path just happened to not hit anything vital. That officer said that he wasn't going to let luck determine the outcome etc etc... but he totally lucked out! If someone gets shot in the chin with a .45 - it could just as easily have passed through a major blood vessel as not, it came out his neck from his chin - how close must it have passed to a cartid artery? It could have gone straight back and his spine. I think it was important for him to fight to survive - to fight back instead of laying doen, because probably one of those "pot shots" would have caught him in the head. You can play possum when someone's shooting at you - even if they are walking away while doing it. So it's good that he said he wasn't going to leave it up to luck, but considering he took one on the chin right off the bat - he was lucky it didn't kill him right then and there. |

I am not ballistics expert at all but it seems I heard somewhere that the low velocity of the .45 ACP is one of the reasons it is such a devastating round. Can someone here with more expertise school me on this?

Here is the incident in greater detail as written by Massad Ayoob in American Handgunner.
I knew the story sounded familiar. http://findarticles.com/p/articles/m...g=content;col1 |

45 HPs would have likely flattened and done less damage. As it was the police officer took a terrific 230 gr fmj hit to the jaw that would have ended the fight right there (in most cases).
The perp's problem was not the 230 gr 45 ACP ammo, it did what it was supposed to do. The perp's problem was that he picked a fight with Robocop. My congratulations to the officer, he 1. thru sheer determination refused to go down, and 2. kept his cool (kept putting rounds on target) despite debilitating injury and stunning pain. Good to hear the officer survived against heavy odds (the perp was well armed and a tough too), job well done.

I thought about the possibility that a hollow point would not have punched through so cleanly and would have delivered more energy to the jaw.
If you take a blow to the jaw of sufficient strength the kinetic shock will transfer to your brain rendering you unconscious. Maybe if the perp had been using HPs the police officer would have lost consciousness... |

Count, that is an interesting point.
I have not been shot in the jaw by 45 HP and fmj to compare results. Now in the good officer’s case the jaw was broken and the teeth went horizontal, meaning he had to be stunned and in pain too…would a hollow point impact harder? My gut feeling is that HP bullet flattening /spreading would somewhat dissipate the impact, more of a splat than a concentrated strike, meaning less shock. Bear in mind also that fmj bullets can also flatten/distort to a certain degree depending on what they strike. Years ago when researching the Miami shootout, it surprised me that the two perps suffered 4 hits to the skull from 38 spl +P HP ammo that flattened, fell off, and did not stop them. All I can tell you is that police officer sure passed the tough man test.

Guys jaww was broke, when I boxed I saw a few guys lay it on and break a jaw, some droped many fought on. Ali had his jaw broke by norton in an early round ali went on to win that fight. CNS will drop a person, anywhere else is a crap shoot. No matter tha caliber, no matter the round HP or fmj. |

I test all my carry ammo, and penetration is at the top of my list. I’ve done 2x4s, metal, pork ribs, telephone books, etc. Tho I haven’t tested a lot of specialty HP ammo, I have found that fmj goes deeper and smashes thru, HP not so much.
But don’t believe me, read Officer Lang’s story, in a gunfight he needed all 14 rounds of 45 ACP 185 gr +P jacketed HPs in his Glock 21 to stop one slightly built perp. Officer lang was “not pleased with his bullets’ performance…He feels…his..bullets did not penetrate as much as might have been optimal.” ---American Handgunner, May-June, 2011, p. 95 It is an important tactical decision as to what ammo you carry, for me its fmj.

There is no such thing as a one shot stop round.
People have been shot in the head with CROWBARS and were still lucid. I know of a few incidents where shotguns with buckshot didn't drop them. Sure, aim strait and use as powerful a round/handgun as you can control, but don't think for a minute it's some super weapon. Deaf

There are a few cases to consider - there is the case of Ron Hunt. He fell from a ladder and had an 18" auger go into his eye and through his skull. It was a 1.5" diameter auger - so in equivalent hand gun caliber it was three times the width of a .500 S&W Magnum, and more than adequate penetration, pretty good shot placement too - I mean if you can shoot someone in the eye with 1.50 cal round with 18" guaranteed penetration, you sort of expect to kill him. But Ron not only lived but was conscious throughout the ordeal:
http://www.snopes.com/horrors/techno/drillbit.asp There is also the case of Phineas Gage. Phineas was injured in an accident preparing to lay rail for a railroad. An accidental explosion of a charge he had set blew his tamping iron through his head. The tamping iron was 3 feet 7 inches long and weighed 13 1/2 pounds. It was 1 1/4 inches in diameter at one end and tapered over a distance of about 1-foot to a diameter of 1/4 inch at the other. The tamping iron went in point first under his left cheek bone and completely out through the top of his head, landing about 25 to 30 yards behind him. Phineas was knocked over but may not have lost consciousness even though most of the front part of the left side of his brain was destroyed Again… if you can shoot someone with 1.25 caliber round and send it clean through his head – you expect to kill him. According to Evan Marshall and Ed Sanow the 1.50 caliber auger round which reliably penetrates bone and flesh up to 18” has 0% street success. The 1.25 caliber tamping iron round which likewise completely penetrates bone also has a 0% street success rate. Me personally, if I had a choice between shooting someone with a .40 caliber bullet or a 1.25 caliber tamping iron – I’d choose the tamping iron. But that’s just me. I just think it goes to show that there is no such thing as a “one shot stop”. It was an attempt to measure bullet effectiveness, it wasn’t a bad idea, but those two guys staked their livelihood on it – it became “their thing”. They were making money off the books, speaking etc.. and because of that – even when problems came to light about their methodology or data gathering or validity of their conclusions they had to defend their shtick to the very hilt. I think they started out with good intentions, but they were over their heads scientifically, medically, mathematically and statistically speaking. I personally think that after looking at issues, it’s just not possible to even qualify in a statistically reliable way - this thing called a “one shot stop”. And for addition reasons, it’s not possible to glean a statistically reliable correlation between this nebulously defined “one shot stop” and “ammo effectiveness” (another nebulous term). .

PK,
I've seen .44Mag HP rounds fail to penetrate the shoulders of boar, when fired from a Marlin carbine. Stuck in the cartilage. I've seen a guy hit a hog in the wrong spot on the skull with a .357 JHP, and have it accomplish exactly nothing. But I've never heard of a service-grade JHP or HP bouncing off a human rib cage, if not at a glancing angle in the first place. |

“Again… if you can shoot someone with 1.25 caliber round and send it clean through his head – you expect to kill him….. think it goes to show that there is no such thing as a “one shot stop”.
Then how does one explain all the folks that have been stopped with one shot…an early example being the gunfight between Davis Tutt and Wild Bill Hickok. At a distance of 75 yards (225 feet) both men fired once, Davis Tutt was stopped (and died) at the scene, shot thru the heart. Hickoks handgun on that day was a 36 cal 1851 Navy Colt.

Seaman, he obviously means there's no such thing as a guaranteed one shot stop, and that Marshall and Sanow's "96% stop" is based on dubious scientific method.

Don’t know anything about Marshall and Sanow’s “96% stop.”
Forgive my ignorance (and confusion), but wouldn’t a shot thru the heart qualify as a “guaranteed one shot stop.” Many years ago, my favorite President, the scholar /soldier /explorer /Nobel Laureate Theodore Roosevelt said that to stop an enemy you had to shoot them in the brain, the heart, or the spine, and call me old fashioned but I tend to agree.

Just goes to show that averages are just that. You may end up at one end or the other of the bell curve.
Occasionally, people die from one round of .22LR. Occasionally, people survive multiple rounds of .45 acp. Each is the exception to the rule. If you want to bet on the long shot, go for it. Someone wins the lottery ever week. They make the headlines. But the reality is, millions of others don't. Most of us examine the data, and bet on the more likely outcome. |

Seaman, people have survived heart punctures. Odds don't favor it, but it happens.
Had a friend who had back to back hog hunts get "interesting" when he went for heart shots. He was using a Ruger Security Six 6" .357. First hog, on butchering discovered the first round hit the heart. Hog charged my friend, who dropped it with the second shot, to the head. Second hog, on butchering discovered the first round severed the aorta. Hog charged my friend, who this time turned and ran to his nearby car. Hog charged and tusk raked the car, denting the driver's door. My friend grabbed a Mini14 from the back seat, and shot the hog in the head through the driver's window. So, for hogs anyway, heart and aorta shots aren't guaranteed to produce a now, now, now stop. So, no, there are no guarantees. High probabilities, sure, guarantees, not so much. Keep shooting until the threat ceases. |

don't know about hogs, but a human can continue to attack for 15 seconds after their heart's been completely obliterated by a bullet according to Dr. Fackler.
more than enough time to fire off a few shots. |

Those of us who've had the privilege of knowing Detective Jared Reston know he's a role model cop. If you have 18 minutes to spare, you can learn more from Jared about this shooting in the interview he granted the ProArms Podcast, http://proarmspodcast.com/2010/03/14...-jared-reston/. Jared's discussion of the incident appears at 33:00 into the podcast.
As you'll hear host Steve Denney (a former SWAT officer himself) explain, Jared is a helluva good shot, too. It has been a pleasure to shoot with him. He has since been in another fatal OIS, also eminently justified and cleared by the prosecutor's office as such. Instructors here are free to download the podcast and use it for training. |

In watching a demonstration of a mechanical device, six 6" plates, built by two brothers, and though the two brothers were not firearms instructors, they were making statements to these young officers, off the cuff.
My function was as a monitor, on the two Engineers. When they started berating the Officers who hit 2" below the plate, big bullet strike on the flat support beam. I jumped in, and told the class that the equipment was great, but the advice was flawed, Bringing a big young man to the front of the class, I had him stand against the equipment. Measured the "Miss" then showed the class 2" below the chin! Two inch low of a hit with a 9mm, 147g Hollow Point, at 1000fps! Right through the throat, and spine? A miss!! Ended with some humor, the plates were good gear, they reset on their own. Head shots are good most of the time, a center hit in the throat, is good all of the time, even if not aimed for. |
