Would be an interesting experiment. But dangerous? Not as dangerous if these were being fired from out of a chamber and barrel.

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.

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.

I watch these guys for years and years. And still they manage to amaze me. This is one of their best videos!

It would be interesting to see how far the bullet would go if you could put a backing plate behind it so the shell can’t come back towards the gun, a plate with a hole you’re shooting through to set off the primer. I think a lot of the energy is split sending the casing backwards and the bullet forward, obviously it wouldn’t go as far as a sealed barrel but I wonder if it would go half as far or how much lower the velocity would be.

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.

4:53 the propellant actually never burns, basically what happens is the primer gets hit and goes off and pressurizes the inside of the cartridge, pushing it out and back at the pinfire gun, but the pinfire gun is still not done shooting out hot gasses into the already pressurized cartridge, so that's why the first wave of powder flies out, it's like if you were to blow into a cup of flower and then a bunch of it flies back at your face. Then when the pinfire gun stops pushing gas into the cartridge, it creates a vacuum effect and pulls the high pressure air out of the cartridge and into the normal pressure air, which pulls some more of the powder along with it.

"Size doesn't matter, it is all about how you do it" - That Gun.

I remember Mythbusters cooking off some centrefire bullets (literally) in an oven, and they found that the case shatters before the bullet leaves the casing. I was completely expecting that to happen here, but I totally did not expect the primers to leave the casings first to give the expanding gases a way out! This was an amazing and insightful video!

Жыл бұрын

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.

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.

This makes full auto guns even more impressive. To fire a bullet, open and expend the empty cartridge, replace a new one, close again to allow the proper pressure for the next bullet in rapid succession

i love shots like this, where you see the hammer slam forward, and before the pin actually engages and fires the round, you see the Hammer already springing back from the impact, i love those shots

The parts that came off the rear of the complete round were the primer and anvil. The primer is made up of a primer cup, primary explosive compound, and the anvil. Primary explosive compound is what is used to initiate the propellant inside the cartridge case. Usually consists of lead azide, lead styphnate or a combination of other primary compounds. The anvil has 2 purposes inside the primer cup; it allows the primary explosive compound to break causing it to “detonate” (which initiates the propellant inside the cartridge case) and also acts as a “cushion” for the firing pin which prevents the firing pin from piercing the primer cup.

oooo you can see the anvil come flying out. Interesting how the cup needs a secure bolt face to keep it in place so the cup (the round thing that flies out first) +anvil (three-pronged thing flying out 2nd) can compress all the ignited material forward to then ignite the powder in the casing. The first shot illustrates this so well!

I think it's just coincidental. You need just enough metal to make the round be durable when outside the gun, and not too much so it isn't too heavy. Also brass is very soft, so it creates a good gas seal, and also it doesn't shrapnel much.

As others have said, it’s more of a coincidence than an intentional design feature. A firearm uses the pressure of the gas directed in a uniform direction out the barrel over a distance. With no barrel all the forces dissipate in random directions.

@bobjohnson1633

Жыл бұрын

It's not engineered to do that. The brass case is a gasket, a sleeve that is supposed to expand to the walls of the barrel or charge hole, and the pressure builds up. Having the cartridge outside of a chamber simply stretches the gasket, which expands as far as it needs to. It is equivalent to pushing against somebody with an open palm, 5# of weight as opposed to pushing a knife against a person at 5# of weight. It has to be focused.

what i love about slow mo guys content is that most of this stuff is too fast for the human eye to see, so even though we know how most of this stuff works, we'd usually never had the chance to see it actually happen in such detail before, but this kind of footage makes it possible to like...double confirm the physics and chemical reactions of things. it makes it doubly interesting to watch for me because of that

Amazing footage!! Would love to maybe see it revisited but with a backing with a hole behind the bullet so the cartridge can't fire backward. (i.e. using the 1" gun as a proper hammer replacement) I wonder if it's also possible to find a clear (plexy or something stronger) barrel so we could observe an amazing Slow Mo of the bullet taking off?

So, the question that is the title has been answered: Yes, it can. However, without a barrel to channel the energy, or something to hold the casing in place, Newton's 3rd Law enacts itself on the bullet _and_ casing, sending both flying in opposite directions with equal momentum. Perhaps a makeshift gun barrel would solve this? Seeing a micro gun actually fire a bullet at speed would be awesome!

The best part of it, is that you are not 2 guys playing with a slowmo cam. You explain all the science around it.

Neat to learn that without the firing pin up against the primer, the primer pushes backward out of the bullet casing. Demonstrates an interesting facet of firearm design.

I always love those sounds you put in during the slow mo, it's so satisfying to hear

God living in an era with slow-mo camera is amazing

That last one, the micro shot...that looks straight out of a movie, like a dust storm on an alien world battering a rocket trying to escape to orbit, that's what that looked like. I would have loved to have seen a shotgun shell.

Just a tip the fully assembled ammo is called a round which is comprised of a brass casing filled with a powered charge which uses a primer to set off the charge which then sends the fmj projectile down the barrel and the reason the primer came out is because it’s not in a firearm, when a round is an a firearm it’ll be held in place preventing the primer from flying out!
