    Believe it or not, that’s actually one of the more recent revisions to the training. The military has been training to aim for the dick area because everyone has plates that protect center-mass these days. You cannot effectively move AND have armor that restricts your legs from working.

      This is true, we were taught that the “hip box” was a prime target zone for many reasons, body armor being one but also since the pelvic girdle is a main support nexus for musculature, if it is damaged then most of the body is out of commission. Plus, there is a very high likelihood that the femoral artery will be damaged and if so a target is likely to bleed out in a matter of seconds.

    I’ve seen images of men with their testicles in a tourniquet and they did not look well at all. They weren’t even bleeding that much. It was less of a medical emergency and more of a hobby it seems.

      Jfc I hope you’re not serious lol. These are self-defense rounds, meant to break apart inside the attacker or intruder, so you’re not shooting through walls, potentially killing people on the other side.

          These aren’t really that effective compared to a hollow point. They create a big visual in ballistic gel, but in a more realistic medium they act more like an improved FMJ, but still over penetrate badly (which isn’t a good thing in most cases).

          They tend to be recommend as a bear round, where over-penetration is actually valuable and desired.

          The same manufacturer actually makes a deeper cut version that doesn’t over penetrate called the xtreme defender, which is generally still worse than a good hollow point in standard calibers, but can be a good option for weaker calibers like .380, where hollow point under-penetrate.

          however, for 9mm and above, you’re better off with a standard hollow point, which is more effective and far more affordable than the all-copper xtreme rounds.

            Oh, good to know. But how do you assess value? I know we like hp for transferring force but my personal attraction to these was exit wounds.

            Also according to a article I linked later, they break bones?

            That Paul Harrell video is good, though. This was the first skeptical tests I’ve seen put on them. I’ll subscribe to his channel

              When it comes to pistol calibers, raw kinetic energy isn’t really a factor, they’re just too weak to actually induce any sort of hydro-static shock that could cause a permanent rupturing of nearby tissues, you need much higher velocities or energy to do that that, which only rifle rounds or shotgun slugs can reliably induce.

              For pistols, the only mechanism of action they can rely on is the mechanical size of the bullet itself, as the bigger the bullet, the larger the hole, and thus the faster the blood loss. Hollow points are the best method to cause bigger holes.

              Ballistic gel is a somewhat deceptive testing media, as it can show a big permanent wound cavity beyond the size of the bullet itself, which isn’t actually how it would perform in real tissue, which is able to stretch much more than ballistic gel due to it being more elastic. What really matters for pistol rounds is being able to expand as much as possible while also maintaining adequate penetration (12" in gel), so that you can reliably penetrate bone and muscle to reach critical organs from any angle. You also want to ensure that the specific hollow point chosen isn’t prone to being plugged by heavy clothing if you live in colder environments.

              LuckyGunner provides the best comparison of bullets that I’ve personally seen for every pistol caliber, allowing you to avoid bullets that don’t adequately penetrate, expand, or over-penetrate. Take note of the actual size of the expanded bullet they show, which is what the actual size of the wound itself would be.

              All defensive pistol calibers break bone when struck, the xtreme penetrators will simply penetrate further and through more bone than a hollow point. This makes it act similarly to a hardcast (ultra hard lead that doesn’t deform) flatnose bullet, which are also usually only recommended for bear protection.

              Over-penetration is an extremely negative trait in personal defense against humans, as it means that the bullet will pass through the target into anything behind them, including innocents who you do not intent to hurt. In self defense rounds you want the bullet to stop inside the first target to avoid endangering anything behind them.

              But how do you assess value?

              Xtreme Defenders are a good value for bear protection, but are extremely poor value for self-defense, as they are more expensive than a good hollow point while providing less effective wounding characteristics and increased danger to bystanders.

                Wow that is really disappointing. Is that why that Paul Harrel guy was using food items? And is 357 too slow to cause tearing like that then? Hydrostatic. I was lead to believe this would work like that because of the speed of that round.

                I’ll look up lucky gunner, too. Thanks for breaking all this down for me. It’s looking like bullets have gotten a lot cheaper recently so I might as well get some hp.

                  Yes, the meat analog he uses, though not perfect, is the closest to a real-world test that a regular person could reasonably perform themselves.

                  357 out of a revolver is indeed still too slow, even with lighter bullets. Only in a lever action carbine does 357 start to reach the required power to perform some hydrostatic tearing, since 357 is really able to take advantage of that extra barrel length to increase velocity fairly dramatically.

                  There was an extremely comprehensive video done on real-world wound ballistics that I was struggling to find for my last comment, but I found it just now, once again thanks to Luckygunner.

                  He gives a summary of it here, and also made this video as a supplement, but if you’d like to see the absolute last word on firearm wound ballistics, I’d suggest this full documentary featuring Dr. Martin Fackler (but be warned, it has some quite gory NSFW images as examples).

          Yes, it generates a larger cavity/hole than a JHP (jacketed hollow point) and the article continues comparing JHP to this new round.

          A traditional HP is just that, the center is open, and it almost immediately breaks open on impact so shrapnel sort of goes all over the target. This is safer for everyone involved but might take several shots to stop someone because of the little actual penetration. Especially of a heavy canvas coat is worn it can severely degrade performance.

          This round, is copper filled with a fluid from the sounds of it, but instead of the front opening up in impact, this his there target and spreads from the rear (the fluid moving forward causing cavitation part). This means the round had a chance to penetrate while also expanding and puting pressure on surrounding tissue which causes more damage. Still though, as it expands, it should greatly reduce velocity and not go through the entire target. A JHP might go on 2-5 inches or more based on design and caliber. Maybe this could go 6-10 inches. If it did exit, there’s likely too little force to do extreme damage to whatever else it hits.

          I’ve got some in my safe, but never shot this particular round to experience it myself. I’ve shot all sorts of standard ball, FMJ, JHP, and composite or lead-free rounds of numerous caliber and form factor.

          Not to mention the brand has Defense in its name.

            Oh shit for real? I’m stupid and sent you ones I’m not familiar with because I didn’t actually read it before sending. They also make them without fluid, just a solid bit of copper. Does the same thing but doesn’t expand

            I looked up “fluted penetrator” and just linked the first thing I saw, so thanks for the correction and actually reading the article that I was being too much of a tool to read.

            This is the bullet I should have used in the image and original comment.

              All good man!! There’s a ton of different ammo aimed at different things, so no doubt too many overlap in names and specs, etc.

              Holy shit that guy chose “defensive” ammo of .357 magnum lmao! Is there a .357 that wouldn’t destroy the target? Haha that’s awesome. The 9mm for the 2nd test is far more common, but interesting they’re going for penetration while still expanding. You’d think they contradict each other.

              All I know is, I don’t want to be on the receiving end of any bullets!

                Okay, so that’s the wierd part of them. The author says expansion but it’s not the bullet itself expanding on those. The idea is the bullet stays rigid but those fluted channels and flat nose push matter outward away from the bullet.

                Yeah though, bad wound to try and do any kind of first response on

      there’s a similar one on your arm. the one they give you IVs in. fun fact i was getting an IV removed and i had a fairly new RN (first year on the floor but damned competent. third day on my room and we’d gotten to become friendly. i’m pretty sure she had a family member who’d had a port and had been their caregiver or something) and she had just popped the catheter out of my AC. she pressed down with the cotton ball with her other thumb and… missed. GOOOOSH GOOOOSH GOOOOSH GOOOOSH goes my antecubital all over the room and she turns green. runs out of the room as i slowly and calmly (because i am high as balls on the good hospital painkillers) reach over and put some pressure on. about 30 seconds later she comes back in with a big gauze, i have the bleeding stopped and there were five great big red streaks all across the room. And her now that i think about it i am sure i was so embarrassed i couldn’t look her in the eye. I think i traumatized that poor woman. i’m just like “hey” You really can’t control your instincts until you’ve been through it once or twice.

        Once at a pet store , I reached in the cage to pet a jumbo rat that was sitting out for adoption (cause I love animals) but it bit me. And just happened to hit some main artery in my finger (I didn’t even know bigger ones were in the finger,). I pull my hand back and literally spray blood, 6 feet in diameter around the whole area. It’s on the floor. The cage. The table. The shelf. Like looked like someone got stabbed. And it was just a small puncture bite.

        I mean it hurt but I was distracted by all the mess. So I wrap my gushing finger. And try to clean up my blood that’s everywhere cause I didn’t want a minimum wage worker to have to do it.

        My bf at the time was a very squeamish guy. I actually saw his lips turn blue at the sight and I thought he was going to faint. (Yeah a grown man).

        So I had to drive us both to the ER where I got a tetanus shot and a bandaid. (Not much to do for punctures).

        Also my insurance wanted me to sue the pet store but I refused. They called multiple times. Wanted me to say the pet store was liable for the ER visit.

        Which certainly would have resulted in someone losing their minimum wage job.

        The hospital wanted me to report the animal to have it euthanized. I refused (literally my fault. ). .anywho.

        I just remembered all the blood. And it happened so fast.

        Lucky it was just a finger and I easily put pressure on it and stopped it pretty fast.

        I’ve never put my hand in an unknown animal cage again. 😅

        Dang, were they actually going into an artery there, or was it just a large opening or you were also on blood thinners or something?

        I get an IV every month and they always use a vein, and any bleeding is just a tiny ooze. But I’m holed up for a matter of hours, not days+ as with a hospital stay.

          my veins have always had good return when giving samples, and this was in the big through your elbow vein. antecubital. my preferred placement is basilic. the large looking mid-forearm pinky close to the elbow but not too close to it i can still move my arm without pinching the cath or hitting a valve. I thinkthat’s antecubital and the basilic but it has been a long time sing i taught myself anatomy.

          as far as volume and force and velocity and delta vee i guess this was excessive even for me. i know there’s some blood thinner (warfarin i’m guessing) coating around a lot of IV catheters to help them last a little longer, but all i can explain is we used a larger cath (20 instead of 16) because i was really dehydrated when i arrived and i had just gotten pumped with probably 6 liters of saline because that was the last time my kidneys were going to feel sated until the next time my shitter got jammed.

      A friend of mine got heart surgery through his inner thigh. That artery is huge, so it provides easy access to the heart without needing to go near any organs. It still creeps me out to think about it, on the other hand it is pretty awesome that’s technologically feasible and provides a much safer procedure with a shorter recovery period.
