Quoted: Lethality is a useless metric. If your attacker bled out 2 minutes after turning your skull inside out with a crowbar, you lost the fight decisively. Exsanguination is a lousy defensive incapacitation mechanism. View Quote The most desirable outcome in a self defense situation is one that the doc will never even see. |

Quoted: The data the article is discussing would say that it makes zero difference. Choose ammo that is reliable in your gun, and make good hits. It even states that a 2nd (exit) would doesn't matter. Blood leaving the body vs. blood pooling in the body is the same. View Quote I didn't see any data in the article. I saw one person's interpretation of anecdotes. |

Doesn't matter, the DA will spin it against you no matter what caliber, or bullet style you use.

Quoted: Hollow points are to prevent overpenetration not to increase lethality. View Quote Disagree. Larger diameter means more chance of damaging something important. Ball ammo that is an 1/8 of an inch (0.125") from a major artery would mean cutting said artery open with the same shot placement using a hp that has a 1/4" greater diameter when expanded. A Federal 147gr HST expands to about 0.66", which is almost twice a 0.35" ball ammo diameter. That is 0.15" more on either side. |

Quoted: “What causes death is rapid exsanguination (blood loss). A hit to the central nervous system or head does not guarantee an instantaneous kill.

Quoted: Once you have enough energy to get decent penetration, but don't yet have enough energy to create stretch cavity/hydrostatic "rifle round" damage, it's really not a significant part of the equation. View Quote View All Quotes View All Quotes Quoted: Quoted: Not buying the .380 = .357 magnum Yes shot placement but energy is in the equation too. Once you have enough energy to get decent penetration, but don't yet have enough energy to create stretch cavity/hydrostatic "rifle round" damage, it's really not a significant part of the equation. This is not quite accurate/correct. There is a threshold level of trauma that when exceeded, overloads the CNS and disables the target's motor control, and this is related to the energy delivered per hit. Even below the velocities where the temporary stretch cavity exceeds the surrounding soft tissue's elastic capacity, greater energy delivered per hit, can exceed that threshold disabling the target sooner. While tgat tgreshold differs from individual to individual, a caliber/loading with double the ME, can still reach/exceed the threshold with fewer hits in the exact same spots. As a real world example that may be easier for folks to visualize: Kyokushin karate tournaments are full contact bareknuckle. No punches to the head. Punches to the body only, but kicks and knee strikes are allowed anywhere but the groin and knee joints. (*** Dolph Lundgren was a European Kyokushin Champ, and put Stallone in the hospital for 9 days with a bruised heart, during the filming for Rocky IV, when Stallone was dumb enough to tell Lundgren to "go for it"). Part of the Kyokushin training is torso impact conditioning, as competitors routinely trade punches to the torso, repeatedly. The Kyokushin World Open Tournament Finals 1975-2019 In the conditioning training, gloves may be used (reduces the bruising that would result from bareknuckle impact). The fighter being conditioned, stands with arms raised, or behind their backs (leaving the front of the torso open), as the partner throws combinations all over the torso (heart, liver, spleen etc.) progressively hitting harder and harder. For any given fighter, the harder the punches, the fewer it takes before they eventually buckle (unless you're impact conditioned AND have one heckuva fat layer, you simply can't withstand full power punches indefinitely. You can condition to take a few, but not repeated, consecutive unblocked hits). The bullet impacts have a similar effect. Some folks will be able to withstand more of them (as mentioned exsanguination takes time, even when vitals are struck), but the significantly greater ME, can exceed that threshold faster (likewise, lower ME may not be able to trigger the nervous shock and loss of motor control threshold in some individuals, before exsanguination, much as a flurry of weaker body punches won't drop a conditioned fighter). Difference between ~300ft-lbs and 400ft-lbs is minimal (just as conditioned fighters aren't going to be hampered much by body shots in that range). But full power 10mm, .357, .44 etc. in the 7xx - 1000+ ft-lbs range, you're going to exceed that threshold with fewer hits (ESPECIALLY if ALL the energy is transferred with each shot, vs a pass through with FMJ that only transfers some of the energy). |

That is a lot of words to say shot placement matters and after that the bigger the bullet the better because the more chance it will hit something important.
She failed to find that velocity matters and causes damage all by itself, but she did say rifles matter, which is the same thing I guess. |
|
I also think he perspective is skewed.
It isn't weather a round kills somebody or not because you don't shoot to kill, you shoot to stop the threat. and she has no data on how long those people that end up postmortem or in the ER continued or did not continue in the fight to be a threat after getting shot, which is the most important info. |

The article the OP linked is the opinion of a PA, not a Doctor, who has an ongoing project to "get tourniquets and bleeding control kits right next to AED machines on the wall of every building". She has the perspective of treating GSW's that come to the ER, ie: peripheral vs. central wounds that bleed to death or not. She is also trying her best to get that message out and has a financial interest to do so. Her company teaches courses on trauma bleeding control.
The author of the article then uses more anecdotal evidence from "medical staff" that he spoke to off the record, that multiple hits and caliber size don't matter. The one semi-scientific article he references as provided to him, -even he- admits they conflate projectile size without accounting for velocity. "It rated large bullets (irrespective of speed or weight...) as 4.5 times more likely to kill than with smaller calibers" I'll remember not to shoot people in the arms or legs and to have my own "blowout kit" with tourniquet available, but other than that I'll stick to standardized ballistic gel and barrier tests to decide what pistol caliber or bullet to use. |

Sounds like another "jus as guuuud" argument.

Quoted: The Bren Ten that Sony Crocket carried was chambered in 10mm, not .45 View Quote The tv show guns were both 45 10mm blanks weren’t available so Dornaus & Dixon built two specifically for filming that were set up to specifically run 45 blanks.

Well, since the article starts with a premise that is completely irrelevant to the purposes of a self defense firearm, why would anybody interested in self defense use of a firearm care what it says.
Old age will kill. We are after the most rapid incapacitating. Just because the target is just as likely to die from fmj as jhp has no bearing on if they were stopped from further action equally as quickly. Same argument, to a lesser extent, when comparing calibers. It actually pisses me off that such BS is published as "expert opinion" because there are a bunch of people who don't know better, or don't think it through who base decisions off of it. |

Quoted: I have often debated with myself: What has more value: A hollow point creating a 2x wound channel and putting all of the bullet energy into a target Or A bullet zipping through a body, opening up a second (and usually significant) hemorrhaging wound and the possibility of clipping the spinal cord..... View Quote View All Quotes View All Quotes Quoted: Quoted: In multiple wound ballistic articles that have been published, there doesn't appear to be data that supports the claim in red. I get it, it's counterintuitive and you'd assume that an expanded bullet is more likely to clip an artery or something, but the support data is hard to come by. I have often debated with myself: What has more value: A hollow point creating a 2x wound channel and putting all of the bullet energy into a target Or A bullet zipping through a body, opening up a second (and usually significant) hemorrhaging wound and the possibility of clipping the spinal cord..... I always figured the reason to carry JHP ammo was to reduce chances of over penetration. Article said most of the bleeding from a GSW is internal, so a small exit wound from an FMJ doesn't seem like it would rapidly increase incapacitation speed. IMHO, the only reason to carry a 9mm over a .45 is capacity/size ratio. I am not stupid enough to think that I will be calm if I ever had to draw and shoot, so having 2x the rounds already in the gun is a fair trade. |

I don't know how valid this argument is on the streets, but
shot for shot, of course 45ACP is more lethal than 9mm. The thing is, a typical 9mm has twice the capacity of 45ACP. Typically 15, 17 or so rounds versus 7 or 8. You get twice as many chances and 2 shots of 9mm might be more effective than 1 with 45ACP. Looking at the totality of attributes. Given lighter recoil, easier to score hits with 9mm. This is why an M16 is more effective than an M14, even though 308 / 7.62 > 5.56mm. |

Big chunks of metal flying through a body are more lethal when they hit certain points?

In fact, even a person shot once may not bleed externally. Almost all the blood in the body can be held in the pelvis, and it’s not uncommon for a gunshot victim to bleed externally in a way that does not appear to be life threatening.” Multiple shots increase the likelihood that a vital structure is hit, but does not increase lethality.

All modern handgun rounds are about the same. Wound differences between calibers are so negligible as to be irrelevant, at least according to the people whose job it is to research and design defensive ammo.
