That’s not a crazy assertion. 25ACP was essentially just made to be 22LR power but in a format that feeds better in a magazine and is center fire for reliability. This isn’t far off the same thing but at 22 mag levels, albeit maybe a bit more, as it was supposed to aproximate 9mm but work better in a high RPM subgun (specifically reliable feeding and high capacity). Bonus points for soft body armor penetration, but meh?

[@TheDarksideFNothing]

​@@icejjfish2191 the very long thin straight walled cartridge of the 22 mag is just more difficult to feed reliably. Most cartridges designed for auto loading guns taper ever so slightly along the entire length of the casing (not just the neck where it attaches to the bullet) and aren't as long compared to the diameter of the casing. Those geometry choices just play nicer with feed ramps and and loading mechanisms. A great example is Smith and Wessons 5.7 compared to their almost identical 22mag. Same barrel system but the 5.7 is dramatically more reliable, and not because of dud rounds. Edit: the S&W doesn't seem to be as unreliable as I was thinking. But it does seem to be less reliable than the 5.7 version.

[@Schwarzvogel1]

@@stevefowler1347 You raise a very interesting point about comparing 5.7x28mm to other less powerful, but commonly used pistol cartridges like .380 ACP and .22 WMR. (Un)fortunately and despite the absurd hype, 5.7x28mm doesn't exhibit significantly higher performance than .380 or .22 Mag in any metric except cost, i.e. it costs a hell of a lot more per cartridge than either of those calibers. I have a great deal of disdain for 5.7x28mm primarily because its cost is *not* in any way justified by its performance. It's just a slightly spicier, centerfire .22 WMR... and regarding the rimfire reliability concerns, I'm starting to think those are overblown. Yes, cheap .22 LR sold in 'bucket o' bullets' packaging like Remington Thunderbolts aren't going to be very reliable. Those cartridges are made to be cheap for plinking and training--they aren't intended for self-defense, although they can be used as such if you had nothing else. Would you rely on cheap aluminum case, 115 gr 9x19mm FMJ for defensive use? Of course not, unless you absolutely had nothing better to use. And in some cases, the reliability of your ammo is influenced to some degree by the firearm you are shooting it with: some guns are _very_ picky about ammo selection; some are more omnivorous in whatever they can reliably cycle. Higher quality .22 LR tends to be more reliable, and centerfire cartridges are not immune to reliability issues either. If 5.7x28mm were as cheap as 9x19mm or even if it matched .45 ACP in cost, I'd pick it in a heartbeat over 9mm Parabellum, as I like the concept of it. But the hype and cost don't match the performance in any way, and paying more per round for my pistol range ammo than I do for 5.56x45mm and .223 just seems absurd to me.

Though admittedly it depends on ammo selection. The faster stuff can make it very snappy if you're not ready for it. 4- Also admittedly, it's a cool and fun gun. I like sharing my stuff so every time I go out shooting either my buddies or someone else at the range looks interested and I always offer a magazine to try out. Hell, I had a guy go buy a box of ammo once after the first mag just so he could try it out more. It's unique and fun to talk about and experience. As always, you'll be most effective with what you train on. In pistol calibers especially, shot placement is key. If you can't control your shot and put them where you need to, the caliber just doesn't make enough of a difference.

I want to comment on the determination of the temporary cavity size. In this video at 8:08 the dimensions shown are 3.5" x 4" for 5.7 vs 2.5" x 5" for 9mm. I believe the point being made here is that 3.5 * 4 = 14 is approximately the same as 12.5 = 2.5*5. Here, 14/12.5 = 1.12; namely the projected area of the stretch cavity is 12% larger in 5.7 vs 9mm. This is an error. The wound cavities are not the 2D-projections shown, but are 3D-volumes. The dimensionally-correct comparison would be between 3.5^2 * 4 = 49 vs 31.25 = 2.5^2 * 5. Here, the 49/31.25 = 1.57; namely, the 5.7 stretch cavity is approximately 57% larger than the 9mm stretch cavity. The volume of tissue disrupted by stretch from the 5.7 is 57% larger than the tissue disrupted by the stretch from 9mm. This is a non-negligible difference. The place for debate here is whether or not the location of the stretch cavity damage is appropriate for the application, and whether the permanent cavity size and penetration favor one over the other, which, of course, you allude to at 8:30

[@LuckyGunner]

What's being measured there is the resulting tearing from the temporary cavity, not the temporary cavity itself. The tearing does not occupy the entire spheroid shape of the temp cavity, so we're not measuring a volume. The tearing usually looks more like an X shape, with two perpendicular tears where the intersecting point is the bullet's path. Sometimes there are more tears, but there are typically two large and distinct ones. We measure each tear giving us a height and width, and note the longer of the two. Then we measure the length of the tear. With both the 5.7 and the 9mm, the temporary cavity damage is well below the threshold of what is typically considered adequate to be a reliable source of incapacitation. At somewhere around 4.5" in height/width and 8" in length, that begins to change. Regardless of the temporary cavity, a 10-12" minimum for penetration is still the priority.

[@camojoe83]

You neglect to add something to this that's very important. Terminal shock. The cavity produced by the pipsqueak is about 300% more damaging because of the shockwave from the speed of impact. Pistol rounds produce a temporary cavity that very rarely exceeds the elasticity of human tissue. It doesn't expand the cavity fast enough nor with enough force.. that's not true with something hitting as fast as the 5.7 or any other high velocity rifle round. So, a much larger wound cavity that's actually effectively permanent with the 5.7 vs the stitch-it-shut groove the regular handgun produces.

[@LuckyGunner]

@thatoldagencyguy Yeah, the 2200 fps is kind of a loose rule of thumb/minimum threshold -- he was not implying that 2200+ fps automatically means an effective temporary wound cavity regardless of other factors.

[@carolkmc2855]

Even when a new round is invented that is indeed "the magic bullet", the that does not diminish current ammo that has proven its effectiveness. For instance, it is not what bullet the victim was shot with, but where the bullet struck the victim. A brain/spine/heart shot victim is not aware whether it was a .22lr or a 500 AE. Those victims have entered eternity and offer no further threat. Fashion trends exist in guns and ammo as it does in clothes.

In that role, what would it offer over .223? The case has drastically less powder capacity, so velocity will never be as high as .223. The smaller 5.7 means it can function in a smaller firearm and the ammo capacity can be higher for the same weight/volume, but neither of those makes a big difference when you're plinking potguts at 100+ yards.

​@@DamageSixnot really, from my point of view, given that rimfire cartridges are typically cheaper to make and buy compared to similar centerfires. Also consider that 5.7 requires a special laquer coating to work well and that the chamber drawings for military use cartridges typically aren't engineered for high levels of accuracy. I am talking theoretically, because i have never seen a varmint rifle in 5.7, but i have reason to suspect that really good accuracy might be hard to achieve.

[@danpearson854]

I heard somewhere that 9mm is just as effective as 10mm because when you are talking about pistols, a hole is a hole, and 9mm makes them faster, has more capacity, and is more controllable. Hmm. 5.7 makes holes faster than 9mm. 5.7 has more capacity than 9mm. 5.7 is more controllable than 9mm. Its just a pistol. A hole is a hole. More holes faster with better placement isnt a thing..... now that the same principles used to justify 9mm are being used against 9mm now that there is a cartridge that out 9mms the 9mm. I own many examples of, and regularly shoot 10, 9, and 5.7. With modern defensive loads, hands down, the one I least want to be hit ONCE by is 10mm. Still, if you are talking a mag dump under pressure, the 9 would probably score more hits, but the 5.7, for exactly the same reasons, would likely score more hits than the 9. The 5.7 handles more like a 22lr than a 9mm in a handgun. Placement and split times are objectively better. More holes, faster, and in more vitals used to be the argument for 9mm. But somehow now its not.

In addition to taking less than optimum angles into account, the 12" is also to add margin for bone and skin (a surprisingly tough barrier, particularly when a round is exiting), as gel just mimics soft tissue. But even more than being "representative" of what a wound would look like gel just offers a standardized medium for comparison between different loadings.

[@robertturley2974]

And he got it wrong. The 12" standard is just that, a standard. Ballistic gel isnt meant to mimic human tissue. 12" of penetration in gel does not equal 12" of penetration in tissue. If that was the case then all the common self defense rounds would be over penetrating and exiting if the person was shot head on. Thats not the case. the 12" gel is meant to be a standard, if it penetrates 12" in gel it will have sufficient penetration in human tissue, but its not 12". The fact the he would say it has anything to do with the location of the vitals being 12" from the side is just flat out incorrect as the gel was never meant to mimic human tissue.

Well you mentioned you wanted it just for fun. 5.7 delivers that in spades. I love the 5.7. It has shortcomings for self defense purposes, it's underwhelming as a rifle cartridge but performs on par with a pistol caliber for its intended purposes. And for that it's longer range ballistics and flatter trajectory compared to 9mm, whole giving you the ability to carry twice for the same weight, and flat shooting, you can easily dump 6 or 7 rounds into a target at greater distances with less recoil whole staying on target compared to other pistol cartridges. So it had merits, but a lot of people tend to oversell it for what it is. It's limited. But also fun and there's definitely use cases for it.

Expansion is important for other rounds, since if they DON'T expand, they will not dump their energy into the target. We can clearly see from this video that 5.7 dumps all of its energy regardless of expansion, and the main concern is its lack of penetration (barely 12 inches in the best case). Serious question for you: Why would you want more expansion on a round that already underpenetrates, and already dumps its energy? That makes no sense.

While it's good to have testing protocols for comparison, the 12" just so happens to be slightly beyond what that one round actually penetrated on that one given shot. That is a shot that came from the side likely because of agents in multiple positions and various angles. So for police, it's clear they'd face more angles like that than a civilian defense is ever likely to. Sure it's possible, but nowhere near odds that LE might experience. And in that case it went thru lung 1st, and just missed the heart. If it had come from the other side, then it stands to reason that it could have hit heart first. If I measure across shoulders, it's ~19". From front to back it's @ sternum ~9.5". So a hit from front-facing into center-mass would need to go ~7.5" to make it 80% of the way through. From the side, 12" penetration on a shot through upper arms means it travels just over 60% of the way through from a shoulder towards the other shoulder. If no shoulder / arms involved, then it's 14" from rib through rib so 60% of that is ~8.5" of penetration. It's arguably just that one situation of a side-shot and only on that one side where the 12" minimum truly applies. Getting hung up on that 12" minimum looks to pretty often get people to dismiss defense options that might actually be a good choice. See it way often with .380. Meanwhile trauma surgeons say it's plenty effective.

But that was years ago on one of the nebulous thousands of gun forums out there; no way I'd be able to find it now. So take it with the truckload of salt that it deserves. IRT to the Fort Hood shooting, the way it was put across to me wasn't so much that people were saying "5.7mm is effective because it killed lots of people!" but rather because during the incident, there were victims who attempted to intervene by physically rushing toward the shooter in an attempt to restrain him. They were shot and immediately incapacitated on the spot. I am loathe to use any kind of criminal victimization as evidence for terminal performance, but if these anecdotes are remotely true then I could see how one might argue that they are *somewhat* more analogous to a defensive application than simply looking at the victims of mass shootings in general.

[@MrGsteele]

The reason that mass matters in temporary cavity formation - as in your comparison of 5.56 vs 7.62 /.308 - has to do with momentum; the greater the mass, the less the bullet slows (for a given frontal area) as it passes through the medium - gel or tissue. For projectiles of a given frontal area, one that stops within the body has an average energy available to transfer to the target animal that ranges between impact energy and zero; for one that passes through at full speed (theoretically, of course - not possible in reality) the energy available to be transferred to create the cavity is at its maximum all the way through. Lighter bullets shed velocity faster, so the temporary cavity is smaller as the bullet exits or reaches its final penetration depth. That's why bullets that pass through a game animal - apart from the benefit of a more pronounced blood trail - will have done more damage in transit than one that stops partway through the animal, even if it stops under the far side of the hide. Again, all assuming that the only difference between the light and heavy projectile is their mass - not other decelerative factors like expansion. Put another way, no one would argue that a 110 grain M1 carbine bullet impacting at, say, 1,800 f/s would do as much damage as, say, a 170 grain .30-30 bullet traveling at the same speed. The 170 grain bullet has more momentum to keep it plowing through the animal at speed. If both exited the target, the 110 grain bullet would exit at a lower speed than the 170 grain directly because of its lower initial momentum.

Due to the lack of immediate incapacitation and high cyclic rate, you'd often have a guy get shot a dozen or more times in a quick bursts. If he died, they'd get sued because, "Why'd you shoot him so many times?!" and if he lived they'd get sued for excessive force/maiming a dude and "why'd you shoot him so many times!?"

Dynamic Shock Index [DSI] = Meplat Diameter x impact velocity - (1500-impact velocity) x sectional density I understand the a company like FK Brno has vested interests in promoting the 7.5 FK round by inventing a new metric where their bullets excel at. But even when we look at raw energy ft-lbs (SBR 10" 5.56 class energy), 2000+ ft/s velocity, sufficient bullet mass (95+ grains), it does look impressive. There are some handgun hunting videos around that would support the claims of its "stopping power". For the sake of arguing "stopping power", can you try to make a presentation comparing the numbers from different pistol and rifle rounds?

This and the recent Garand Thumb 5.7 really compliment each other

[@TheFps12]

I always knew it was lacking. Only thing that makes it that much better than something like .22mag is its center fired so its more reliable and there are more "tactical" modernized options for 5.7 than .22mag when it comes to self defense/duty. If they made .22mag center fired and there was more carry/duty options chambered in it, it would be where 5.7 is now but cheaper.

[@calebdoner]

Perfect timing putting this up right after Garand thumbs video.

[@billy56081]

If it were a locked breach design it would equal or outperform a Hornet slightly.

[@brianhoxworth3881]

​@@billy56081always thought a mini action 5.7 bolt gun would be pretty good. Intermediate power, ok for foxes, coons or the occasional coyote around the farm.

[@jeffreystarits2783]

you can't overlook the fun factor

[@mothman-jz8ug]

I remember when the hottest selling guns were rifles in some 17 caliber centerfire. The 17 Remington was tops in this, but other companies were producing factory rifles chambered for the 17-223. Yes, these things were top of the heap. They're still flying off the shelves, right? Yep, Ive seen more crops of "cartridge de jour" than resurrections of McRib. HERE'S THE FUTURE for the 5.7x28: This caliber will soar to great heights, with sales five years from now rivaling other greats like the 357 Sig and the 45 GAP. In ten years it will be moving like the 5mm Remington Rimfire Magnum.

[@pewpewTN]

5.7x28 is like 10mm in the sense that most factory ammo can be less than 50% of what the cartridge should be. Real 5.7x28 ammo can get very close to 400 ft/lbs (maybe even higher) in a handgun & significantly more in a PDW/carbine. So for me, I will just use the .38 per round stuff for most of my training & use the real ammo more conservatively. The best tip I could give people that want full power for every shot is to buy the cheaper ammo, pull the projectile, load it properly, then re-seat the projectile. Reaching over 2000 FPS with a 40 grain projectile for a handgun is very easy with 5.7x28. So people need to know that most of the info you gave is using the crappy ammo that has been purposely underloaded to try to mitigate the "AP" claims.

[@masonlariscy9143]

I've wondered if 5.7 suffered from 10mm-itis for a few years, and I'm glad someone has come to the same conclusion. 5.7 might just be starting to hit a golden era

[@TurboTaco2JZ]

I can't tell if it's deliberate or just incompetence by the popular KZbin channels to ignore this fact. The majority of popular 5.7 videos showcase the most watered down options and try to pass it as conclusive evidence. Imagine if the general 2A audience was shown 10mm offerings with the performance of 40S&W. They would easily be able to point out the farce. I wish the same audience could point it out when the exact situation occurs with the 5.7x28.

[@BcFuTw9jt]

Zero of that is true, I've used your "real ammo" and the difference if any wouldn't be enough to make a difference

[@pewpewTN]

@TurboTaco2JZ I think it's mostly incompetence. They just don't know anything about the cartridge. All they do is read or watch the stuff that the guy before them published. Trying to pump out content that will get clicks. Buffman's Range does some really solid testing with everything from crappy bulk ammo to the high end stuff, so he is a great source of info on the 5.7x28 game. He has been at it for years. I got into the cartridge about 10 years ago & he is the person I got my info from when I was first dipping my toe into the water.

[@TurboTaco2JZ]

@BcFuTw9jt you are right 1700 fps vs 2300 fps is insignificant and I quote "the difference if any wouldn't be enough to make a difference" It makes so little sense that it makes any sense but enough sense

[@GregNTech]

Stop shooting me.... 😂😅😅😂😅😅😂

Perp got shot “10-12 times”, asked to stop being shot, and ultimately survived. Yeah that’s 5.7’s mail in the coffin as far as I’m concerned LOL

A completely unvalidated story, the only things validated is that it was 5.7 and the person died at the scene

WHEN IS PART 2 COMING OUT??

[@Two_Years]

I feel like 5.7 would be best as a survival or bug out caliber to replace .22 if your wallet can handle it. I would be very impressed by something like the ar-7 in 5.7. The caliber is lighter than many other calibers, and has the benefit of having a more reliable primer over rimfire. Just a thought.

[@Stevarooni]

Basically, a PS90 (with shorter barrel) fits what you're talking about. I'm sure there are good, sturdy cases for a PS90 that would add durability and the ability to float.

[@max-zv7sf]

5.7's ballistics are very close to .22Hornet. Used in the M4 and M6 survival rifles during the ww2- Korea period. Probably i would still give the nod to the Hornet, given that its rimmed case works better for lightweight break action gun combining a shotgun and a small bore rifle barrel.

[@Enjoyer.762]

Bug out is a dumb concept.

[@Two_Years]

@@Enjoyer.762 I agree. Just stay in. I just don't have another term for it. Hiking/backpacking gun?

[@TedJ71]

Try to replace that ammo in that situation !

[@nicoscarfo4486]

None of the commercial 5.7×28 is loaded anywhere near the max pressure of 50,038 only custom ammo will unlock the 5.7s full potential

[@wpherigo1]

Your videos are always excellent. GarandThumb dropped a video on 1/7/24 discussing this very cartridge. He was, uh, not super impressed and disappointed that anyone in the military or law enforcement might have to rely on it. Being quite rotund myself, 8” of penetration wouldn’t make it half way thru me, but I’d hate to get shot by it or anything else. I suspect that’s how the guy got shot 10 times and asked them to quit shooting him!

[@KwarterCraft]

Not sure what you have coming up for part two, but based on what I've seen so far 9mm remains the king for CC. Cheap and effective is a hard combo to beat.

[@Jackoff_Smirnoff]

No, it is actually a lethal round. It won the NATO ballistic requirements, but Germany started up as always. The thing has no arch, it does need a flash suppressor. The round cuts through body armor like Swiss cheese (talking military rounds). Barely no roil, which keeps you peppering the target(s). Shame, we always go with bigger calibers, when placement is more important in combat. The round is expensive, but with economies of scale that would have been solved.

[@lanedexter6303]

Fascinating, Chris. Sounds like 5.7 is about right for midnight marauding raccoons, but nothing more (so is the .380 in my bathrobe pocket). I’m old and my primary pistol is old, so I’ll stick with big bullets. But 5.7 looks like a fun toy.

[@dannyd.9932]

IIRC the secret service uses the P90 for its compactness but they also like 10-14” AR15s

[@alanhelton]

I like both calibers. Owned both for years. They aren’t the same animal, but more like divergent evolution.

[@sterlingroberts6240]

Cartidges like these are designed for support personnel, where the flatter trajectory and low recoil are likely more important than raw power or penetration. The compact size of the actual firearms is also a strong consideration. Expensive ammunition matters less than with the average frontline infantryman, as support personal won’t need to fire their weapons as often.

[@certaindeaf8315]

Perhaps the .44 magnum they compared it to was a .22 short. Honest mistake.

[@Jonfocus03]

How long until Pt2? REALLY interested to see that that T6B does.

[@greatwhtrabbitt]

I know someone who was one of the first on scene at ft hood. What he described was terrible. Won’t go into details, but 5.7 at close range is absolutely lethal.
