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

Pay no attention to these scam accounts using the same name and picture as this account in the comments. Unless "The Slow Mo Guys" is in a bubble with a check/tick mark next to it, it's not us. I will never contact you on any platform with a free gift or any offer like that, as much as I love you. I know most people already know this but I've had a few emails recently where people seem to have fallen for it. Doing my best to ban them from the channel but it's hard to stay on top of all of them. Be safe out there my friends! - Gav

That macro shot with the probe lens is absolutely incredible!

How much could this be escalated? Like a domino effect of bullets from the tiny round up to a tank shell.

It amazes me that after all these years they continue to make consistently high quality content

There's a type of gun that used mini rockets as ammo called Gyrojets, and they are kinda rare and hard to find, so there's precious little videos of them working on youtube, and I haven't been able to find any video with slow motion action, let alone super slow motion. A tiny rocket bullet might be something really fun to see in superslow motion, and I'd like to leave my suggestion for you guys if you think you can get your hands on a gyrojet pistol.

These guys are some of the only OGs of youtube still making stuff. not only that, their content has just gotten better and better

What Gav says at the end about the footage still being surprising, despite expecting it, is spot on! Each and every video, I see the title and can imagine roughly how it's going to look, but I'm then blown away by how much detail and cool stuff there is to look at. Awesome every time, and still getting better 11 years on!

13:05 This shot is just unbelievable

I like how they probably actually achieved the world record for the shortest distance a bullet has ever been fired and nobody mentions it 😂

That macro shot is probably one of the best clips you've ever recorded. Absolutely incredible

Ever since Dan and Gav got back together on camera their ideas have been absolute bangers, that shaped charge video had me chuffed

The “percussion cap” is called a primer, the round thing with the 3 holes is called the anvil. When a gun fires normally, the primer still has the firing pin against it to prevent it coming out, but occasionally you have a primer rupture, and just like here, the powder burns, but the path of least resistance is out the primer pocket

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. I know I'm a huge nerd for this, but I couldn't help myself

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

"We're the slowmo guys, still at it" Really hit me in the feels. God I love these guys

Its a shame they did not think to clamp the cartridge a bit so that the bullet could really fly.

I love the genuine curiosity of these guys. It's infectious. Thanks for another piece of quality edutainment.

We can all agree this is some amazing slow motion footage, but can we take a minute to appreciate Gav's audio design in these videos?! I remember a video some time ago where he explained how he adds most of the audio in these videos and this one is so incredibly satisfying!

I appreciate your gun safety Dan, even when the gun is so tiny you could accidentally swallow it, you still take it seriously. Good on you

Seems to me like a security feature, having the ignition cap blow out if there's nothing to hold it in place, to ensure that people don't get hurt when they're playing around with these bullets.
