Can a 2 Inch Gun Fire a 1 Inch Bullet? - 300,000FPS - The Slow Mo Guys 

First time I've seen a RU-vid channel acknowledge this problem that has been going on for quite some time now

@@Johannesburgus the slow mo guys are just real MVPs

Try it with a 12 gauge shell.

@@CryMoreQT 🤓 Well actually, since it’s a decimal, saying two two is technically more accurate then twenty two. According to my research all Brits say it this way. Sorry, I had to put on my geek glasses for that one…

Hey would y'all be interested in filming one of my catapults, or trebuchet? Here's a couple of short videos of the catapult I'd like to see in slow motion. It's transonic, but I can get it supersonic. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-7NF4FhVHqp0.html ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-cMx0qRwzZwg.html

10megaton.

The most dangerous video. Loose bullets firing bigger, loose bullets

what a good idea!

I think unless theres another barrel its going to immediately fail.

@@LexanderMiller well potentially. As you saw with the 9 mm it was traveling extremely slowly. While it travelled a fair bit it could hardly be considered deadly or even dangerous. For a bullet to be dangerous it needs to be traveling very fast. Though it may simply be impossible for a 9mm bullet to actually hit the primer of say a 10mm cartridge. Would be an interesting experiment. But dangerous? Not as dangerous if these were being fired from out of a chamber and barrel.

Completely! It's one of the best things my eyes has ever seen!

It really was. I'd love to see them explore that more with better lighting and slower frame rates

They should have gone and shot at the bullet side too

Reminded me of a CGI movie shot

A very cool reminder of how relatively soft copper is.

Yeah even going through the "RU-vid Originals" experience somehow couldn't corrupt these two. These are solid men right here.

the sound as the hammer struck on that delayed shot was one of the coolest things I've ever heard, easily

I was just thinking this. Is it the actual audio or does he add sound effects?

@@rixxey2048 he adds sound effects and also slows down certain sounds. None of the noises a real in a sense that if you slowed it down that much it wouldn't sound right

Yeah, seriously; as a hobbyist working with audio on occasion I've a good ear for sound effects and I love that there's other folks out there who appreciate them as much as I do, because holy cow does it make phenomenal difference to presentation haha

@@rixxey2048 Actual audio slowed down more than ~100X becomes so low pitched that it's beyond the range of human hearing, so they have to add the sound effects in.

I think thats a great idea. I made the same comment. Would be super interesting to see

The back plate with a hole is a great idea I love that, I had a similar thought. What if the bullet was inside a transparent barrel?(so that you can see the bullet with the camera). Couldn't that make the bullet fly nice and straight out of the barrel since the barrel could act as some kind of chamber where the gas that's expanding keeps trapped inside shooting the bullet out the other way. It could actually shoot the bullet out further perhaps. Connect that barrel to the back plate with the hole and that should keep most of the propellant and gas between the bullet and the inside of the back plate, this could ignite the propellant more creating more gas, shooting the bullet even further! Note on the back plate hole: it should be smaller than the hole created inside the casing after the percussion cap flies out so that the percussion cap also stays inside the barrel with the back plate acting like the back plate, keeping the explosion and gas trapped inside the chamber even more.

The little gun doesn't have enough energy to push a firing pin.

Literally just use a slow mo camera. It’s hardly genius

What happened?

@@Gonzakoable theyve just been doing this for forever lol, its nice to see them still going

@@Gonzakoable Well, you know, firing bullets at bullets like this, it's sort of a miracle.

It's nice that they haven't coporiatised with, massive crew and brand pleasing etc, it's still two dudes goofing around with a high speed camera.

@@rejuvenatingsoul3498 i love them BECAUSE of it

First rule of tiny gun safety is to point it away from whoever you want not your gun eaten 🤣

Overly cautious mental illness

I was thinking the same thing. Though this is my first video, so when I saw the tiny gun as they introduced it at the start, my first reflex thought was " Gun! Don't point it to close to your buddy's face! Always treat it as if it's loaded! Wear safety glasses" 😅.

@@lukecook9421 didn't seem noteworthy to me. What about it?

@@lukecook9421 you can call it cap or primer.

the cartridge would probably explode in that case because there is no firing chamber to prevent that

@@HECKproductions the cartridge won't explode unless it overloaded. It would shoot the bullet or blow out the cap before it exploded.

@@270Winchester I'm not so sure... The barrel does a lot to contain the expanding gas, including acting as reinforcement for the shell. With nothing holding it we saw that .22 shell get launched backwards with enough force that hitting the mini gun crumpled it like a soda can. With a backstop that force is limited to just the bullet and the shell walls. The .22 might survive, or it might get a bit of flowering fracturs at the end. I wish they would have tested it, because I'm really not sure what would happen.

It blew the primer

@Ben Dover Its always laughable when people think a bunch of militia with hand held weapons they have a chance against the might of the US military. 😂😂🤣🤣

many bullets have been fired at shorter distances.... sorry to be morbid, but they press them to the target so they dont miss and only injure themselves....

​@@vtwinnerthat would still require the bullet to leave the end of a barrel, at least a few inches. That bullet didn't even leave the casing.

@@WhaIHuhWhatDoYouMean a bullet has not been fired if it hasn't left the casing... it was just nudged.. that one anyway...... the cap was fired... the bullet not so much

​@@vtwinner it didn't even fully leave the casing, I think that beats it.

@@jeremybree1986 If it hasn't left the casing, it hasn't been fired, that is called a MIS-fire

Yeah, that was something special. Very unique.

Just think about how far this specific technology has come in such a short amount of time. It's truly amazing that we are able to capture such insanely fast events and slow them down so we can take in every step it has taken on the way while maintaining such detail. It's just beautiful..

I had a similar experience smacking a 12 gauge shell capped off on a coffee table it threw the percussion cap through my hand, I didn’t realize because it happened so fast until I started seeing drops of blood

@@arizonaballistics bruh

@@arizonaballistics like literally through your hand?

Especially with the 9mm, you really need the firing pin to hold the primer bit in place, never occurred to me

The shell will actually expand slightly inside the chamber, which makes it friction fit and fire form to the inside of the chamber. This is why ejecting spent rounds is more difficult than expecting unfired rounds (and why part of the reloading process involves recompressing the shell to its original size). If you oil the shell, you can damage some of the weaker actions because the shell becomes a projectile that slams into the back of the action.

I love how with the .22 the Bullet seems to hover there for a moment while the casing flies backward because it takes longer to overcome its inertia.

Demonstrates the law of conservation of momentum, to be precise. The bullet's mass times its velocity will be equal to the casing's mass times its velocity; since the bullet is much more massive, the casing will have a much greater velocity.

The primer does it all. The primer compound ignites, builds up enough pressure to push itself out of the primer pocket, which it can as it is not held in by a breech (Nothing to do with a firing pin). Occasionally there is enough pressure generated by the primer to move the bullet forward and the case backward, but never enough heat and pressure in the case to ignite the smokeless powder, as this needs both do that and to build up pressure. Smokeless powder is hard to ignite. Try it again with black powder as a propellant....Even in a firearm it is, by choosing the wrong combination of primer, smokeless powder and bullet-case friction possible to have a failure to ignite the powder in which the bullet just moves a little on primer pressure alone. Enlarging the confined space the powder is in, making it even harder to ignite. That js the reason why we have normal primers and magnum primers that generate more heat and pressure. So Thats why the primer pressure in the case just blows out the unburnt powder through the flash hole. The rimfire is different. No separate primer that can blow out and release the pressure, very finely granulated smokeless powder that is easier to ignite and burns faster, and this generates the heat and pressure to move the case (the primer) back and the bullet a little forward.

That is exactly what happened. I have heard of this happening but I have never witnessed it.

There is also the problem of not having an enclosed chamber. Part of the purpose of the barrel in a firearm is to prevent the pressure from blowing the unburnt powder away. With an enclosed chamber + barrel, the powder is still in the enclosed space catching fire. You could probably prevent the primer rupture by using rimfire instead of centerfire, but you would still have the problems of pressure and unburnt powder escaping out the front.

@@ShaggyRogers1 you still get rims popping with rimfire.

I don't think they are intentionally designed to blow out for safety, it's just that the primers and bullets would be harder to manufacture if they were crimped in place more securely

@@rokoala2636 I'm not sure it's universal, but some military ammo does have the primer crimped in.

​@@paullockyer7230 I would say it's probably more common than not for military ammo fwiw. Last thing you want is loose primer cases floating around the innards during an engagement.

Twinrehz - primers are crimped in when the application calls for high reliability. They protect the gun not people playing around doing wrong things wrongly.

@@paullockyer7230 yeah true, I was more meaning crimped in securely enough to affect the proposed 'safety feature' of having them blow out. I reckon that would need a decent change to the primer and crimping compared to how they do it for military ammo.

"Too Many Super Shotguns"

I think there are videos of people just whacking the primer on a shotgun shell without a barrel and it basically does nothing!

@@El-Burrito To set off a primer you need at least a slightly pointing tip otherwise the force is too evenly distributed.

Many people perform this experiment by lobbing some 22lr rounds into a fire while partying.

@@Hawk7886 Yeah ...22lr?....My brother and i tried this, its not as much fun when using artillery shells...RIP bro, you are missed!!

You never considered what might happen for a round to go off outside the gun, are you an NPC?

Wow...

As I said above - Kinda disproves the myth that cartridges in a fire shoot the bullets everywhere. Without the barrel to direct the force, the casings just blow off.

My jaw literally dropped...

It's actually nearly unbelievable how far slow motion technology has come in such a ridiculously short amount of time!

it was like a movie scene suddenly in a middle of a dessert.

True!

Gav as far as I know edits most of it himself. He’s done a video about his editing before

@@nz540im3 that's wicked!

"he sounds aren't recorded in slow motion too or something, but are edited in afterwards. " Are you sure about that? I;ve taken ultra slow motion videos on my Android of my dogs and I hear the sounds recorded in slow motion, the sounds almost seem amplified because I hear dog's toe nails actually making scratching sounds as they run on the concrete

@@HobbyOrganist Unless you paid an obscene amount of money for a phone that has a high speed aperture, I highly doubt you got over 300fps. Dedicated high speed cameras don't have microphone input. The audio is recorded separately and then slowed down to match the video by the millisecond. Most android phones don't even have refresh rates above 144hz, and that's on the pricey ones ($1k and above), so its very unlikely that they'd have apertures capable of much more than that.

@@TheDustyShredder this is incorrect, my phone goes up to 240fps (Pixel 6) and some Samsung flagships have disgustingly high frame rates

hammers hit pins that hit caps in a gun... most pins are pretty tight, much smaller than the casing and leave a centered punch in the cap...

@@vtwinner and what does that have to do with anything? The point havocgear made is that one of the purposes of the firing pin being fixed forward after shooting is that it holds the primer in place. By holding the primer in place, the forces of the explosion are instead directed to the least path of resistance. The path of least resistance being the projectile that is only held in place within the cartridge by friction.

@@ShaggyRogers1 its not fixed forward... the bullet is held by its rim in the breach, not by the PIN...

@@vtwinner The pin holds the primer, you dingus. You see that little cylinder that keeps flying out the back of the round in the video? That's the primer.

What does he do outside of this?

@@iyzyz he spent a few years serving in the Royal British Army. I forget his exact specialty, but he was something of a ballistics and firearms expert during his several years in the military.

The British Army is actually the only branch of the UK military without ‘royal’ in the title. A consequence of the civil war.

The guys that animated the intro to Lord of War WISH they had this footage as reference. I wouldn't be surprised if it is used eventually.

Dwarf has great affects for a cheap to show

It genuinely looks like CGI but it's REAL and that blows my mind.

A pace is a single step and not two steps

@@victorfox9623 I was about to tell you that a pace is two steps, but it's been so long since I did anything resembling scouting that I double-checked. According to Wikipedia, it can be either. I'm in the US, and was taught two steps is a pace. en.wikipedia.org/wiki/Pace_(unit)

Gavin actually does it himself!

“Jessr look over there, those are my best customers! What are they doing jesrey?”

Quite likely that the cooking in an oven weakens the metal casing, so by the time pressure/heat build up enough to ignite the propellant, the casing is too weak to hold itself together before it pushes the bullet away. Setting it off normally, the casing is just fine, which is a good thing. If the casing were sometimes too weak to contain the energy of the propellant and fail while inside a gun, you’d have a nightmare of a jam to try and clear out, shards of broken brass clinking around inside of the gun.

@@ShadowsOfTheSky not enough room for a round to shatter in your chamber. at most the cassing would develop a single crack on the casing wall.

@@ShadowsOfTheSky I also wonder if heating it to the point that the gunpowder ignites would cause more of it to ignite at the same time, making a larger explosion overall than this one, where only a few grains seem to go. But yeah, it's probably more the weakened, more pliable casing.

Here's another thought: maybe the pressure of the primer is pages the printer and bullet out, so the gun powder never has a chance to ignite. Speer used to make special practice agni that used a plastic bullet, and only the primer (zero gun powder). It would throw that plastic bullet at high speed, but even a heavy bullet would be pushed out by the primer alone. Likewise, Aguila makes 22LR ammo called Colibri that launches a 20 grain bullet at 700 feet per second, using only the primer. (A normal 22LR bullet is 40 grains at 1100+ FPS, so Colibri is much less powerful than standard, but also much more powerful than you might guess.)

@@cymond That makes sense as a theoretical argument, but I’ve set off rounds not in a barrel myself where the primer didn’t pop out, and the casing doesn’t shatter. I suppose it’s possible if you used the powder for high velocity round but with a heavy bullet, but I imagine the primer will pop off or the round will be pushed out before the casing fails. I imagine it’s a combination of the metal being weaker at high temps, and also what @MusicalJackknife said above, because all the gunpowder was heated equally, as soon as the reaction started it all went up instantly, creating way more pressure before the expanding gases even had time to push the bullet or primer out, and the case just failed.

Is this real ?

@@helovedher1845 nahhh it’s fake

😂😂

Nice

I would say it’s average

@@arindas8357 yea I've reported it but YT can be slow to take this stuff down

@@Teeepan how is it fraud

@@w..r.i.z.z this was in response to a fraudulent comment that's since been taken down

Yeah, seems like the percussion cap got hit and damaged, and when the primer exploded it fired the percussion cap back out like a bullet (nothing to keep the cap from blowing back). None of the powder exploded because no compression occurred in the bullet to allow the explosion.

@@athingwhichexists the secondary purpose of the firing pine is to hold it in place so that it don't do what we just seen shooting it out of the back of the bullet obviously

@@danhard8440 The firing pin’s only purpose is to strike the primer initiating the explosive train. The breach face of the weapon/bolt is what keeps things in place. Very rudimentary explanation but it works.

@@speedingatheist I think he's talking about the bullet of the small guns which got snapped in half by the casing and the small gun barrel's edges

Yeah they’re the only ones I can think of.. I’m sure there is 1 or 2 more I just can’t think of them off the top of my head.. I’m so glad RU-vid isn’t the way it was back then.. there were some good things about old RU-vid but overall I think it was worse than new RU-vid

a plexiglass tube *might* hold up enough for a lower pressure cartridge, just the once... Would make for a pretty awesome shot too.

Yep or clamp the case in place

Or they could use a ballistic gel block. Embed the 9mm round in the block, and then fire the tiny gun into the back of the 9mm case. Added benefit would be to capture the 9mm projectile.

ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-7pOXunRYJIw.html This is kind of close to what you're saying. He puts a see through suppressor at the end of the barrel so you can see what all the pressure and gasses do behind the bullet

Smarter every day did a video on clear suppresors... and some of them even survive a few shots

So cute❤

Percussion cap is still correct, primer is just more commonly used when referring to cartridges. They were sometimes referred to as "percussion primers" on percussion muzzleloaders back in the day as well.

The distinction is the type of ammo. For this 9mm it's a primer. Percussion caps are used in lower tech muzzle loaders. I don't know the internal differences, but they are a different style of tech
