This Pistol Literally Shoots ROCKET BULLETS!!! 

Honestly, this might be a good way to get a crossover with The Slow Mo Guys, cause I honestly would love to see those bullets fired in super slow-motion and see how it comes out, but also how fast it accelerates.

joel seems like a chill dude :) definitely bring him back, even if he doesnt have anymore super interesting guns he just has a nice chill vibe about him

“Plus! we fire the WHOLE bullet, that’s 65% more bullet per bullet!” -cave johnson, aperture science CEO.

15:32 I know they only loaded one round... I mean rocket, but that reaction of looking down the barrel made me flinch.

Did anyone else notice when the first squib dude literally pointed it at his face and looked down the barrel. This seems even extra dangerous with these rounds

We NEED the slow-mo guys to record the gun firing. The detail and things we would see would be so sick

You should have saved a round to fire in the dark at night.

"Ig ill be the first to fire it, you sure joel?" Joel standing a bit away, looking happy to not fire it: *Yup* fire away!

This turned out amazing, Thank you guys so much for having us out!!

This round is like... The primitive version of the warhammer 40k boltgun round. This is insane.

Joel is a rock star for doing this! Free lifetime membership to DR.

This gun was sold at Aidelman's in Long Island NY in the 70's and if it wasn't because of NY's lousey gun laws I would have owned one! It came in a rifle version as well if I recall. Somewhere around here I still have the Aidelman's catalog. I think it sold for under $200 and the rounds were $2-$3 each. The entire concept fascinated me...

The first squib 15:30 … he looked down the barrel🙀 fine on a normal pistol once cleared but this is a rocket 🚀. Simply brilliant and excellent video.

15:40 So if you think you’ve had a misfire, don’t ever do what he does and look down the barrel of the gun..

The first iteration of the Bolter. Praise the Emperor and his Golden Throne.

The cool factor is off the chart but the sketchy factor is right there with it. hahaha I still wouldn't turn down getting to shoot it just because why would you not shoot a rocket gun, so yes I'm jealous. Thank you to the owner of those for coming out and letting this video get made!

Thank you Joel. Preserving history and sharing it with the world is a priceless gift.

15:36 my heart just stopped omg :O this mans

I appreciate Joel’s beard, it really gave us the look at the air blowing in your faces, you can see his beard blown by it

That was some of the coolest slo mo footage I've seen on this channel

If they started making these again and the ammo it would for sure have a market. Also It's a shame the slow-mo guys couldn't have been on the ranch for this one! 😊

As a long time demolitia fanboy I really appreciate that Joel gave us the chance to see this fantastic gun in action!

Loved how excited Joel was to see the slow motion, what a cool guy to bring such a rare and expensive item for us to learn about and enjoy. Great video!

The Proto-Bolter... We Going 40K up in here

This is BY FAR the best footage of anyone firing the GyroJet. BIG thanks to the guys for bringing that out,and sending those high dollar rounds into space.

That slowmo at 7:53! You can see the acceleration as it travels; amazing! This thing must have the weirdest trajectory if you tried to shoot long-range.

Big UP for Joel Mr. Wonderful! Thanks so much dude! Love from Italy!

Storm troopers not hitting anything makes so much more sense now!

Props to Joel, what an awesome guy letting you shoot so much $$$$$$$ worth of rockets. 👏👏👏

👍 to Joel for sharing your spendy toys and bullets with us🇺🇸🇺🇸

Bless the Emperor! A real life bolter!

I remember my dad telling us about this gun many many years ago. He also told us all the flaws. Just so you know, this was only a few miles from where you are shooting. Thank you for this video.

joel is a true collector. he seems just happy to see people enjoy and fire it, doesn't even care about firing it himself, lol

Yeah Joel is a stand up guy for sure. This is definitely the most in depth gyrojet demonstration video ive ever seen. Im actually pretty impressed with its power tbh.

This was such a fun video to watch. I've looked into this before and all the (very valid) reasons it never caught on, but the *much* higher risk of ricochets never occurred to me. Every other gun loses energy after firing, and much more after hitting something. This is a rocket, speeding up as it goes. It can hit something, bounce around, then accelerate right back towards the wielder - just as deadly as when it left the barrel. It's so obvious after watching the video, but I never heard anyone mention it, nor had i thought of it before.

Joel, you the man. Awesome video, thanks for sharing.

"Gee Lord Commissar, how come the Commissariat lets you have TWO Bolt Pistols?" "So I can execute two fleeing cowards at once"

Freakin awesome to see this. Love demo ranch. I don't want to be THAT guy but I'll admit I got a little triggered safety wise at 15:40 when dude points this at himself. It's already fired and open but it still makes my eye twitch!! Stay safe my friends!!

Thanks to Joel for making this video possible. Back in the 70’s/80’s my dad owned and resold several Gyrojet pistols and rifles. He also knew the inventor and founder of MB Associates that manufactured the Gyrojet. They were located in San Ramon here in the SF Bay Area. Unfortunately he never kept any of the guns and as much as I want one myself, it’s tough to justify since the prices have literally shot to the moon. I do still have a modest collection of rounds though, including several different types of “nozzles”. Weapons for use in space were a genuine concern during the space race, yet fortunately were never needed. Or at least we never heard about it. LOL!!

This is an amazing video. Thanks for showing something I never heard about.

That guy pointing the gun at his own face at 15:43 made me flinch.

Closest we've got so far to the Bolter from Warhammer 40K! I remember reading about these some time ago and I think it was the unreliability of the rounds and the cost that led to them being very short lived on the market

Joel’s beard blowing in the wind from the jet blast @ 12:43.

Joel, thank you for sharing such a rarely seen gun with us.

Joel I know you're watching this and you're the man for sharing this piece of history with us! Thank you!

Joel definitely looks like the kind of guy to collect a lot of weird and whacky things. Such a cool guy!

Insane! Thanks to you guys for showing to the world.

That ammo is extinct to find. Joel is a legend! Great vid!👍🏻👍🏻

Mad props to danny going and finding that round, like a literal needle in a haystack. this is why we love him. RIP mate.

It's too bad you guys didn't do any shots at night. They'd probably look really cool.

The slow motion is so incredibly cool! I’d love to see a company do a modern rocket pistol.

I love your videos man! Its rad to see your channel continue to grow as we all get older lol 😂

I really wanted to see it travel long distance, or try to shoot through a really long chunk of ballistic gel.

Joel is the star if this video... seems like a true collector. Brought a few with him and just wanted to share the hobby and enjoyment.

Oh man....thnx about this presentation. I am full of ideas now...awesome

Met Joel delivering furniture to him. He is every bit as genuine, knowledgeable, and friendly as he appears.

Small Arms Review did a fairly comprehensive article on the Gyrojet story and its developer Richard Mainhardt some years ago. Taofledermaus did what's probably the single best recent test firing of the Gyrojet pistol and carbine a few years ago. Backyard Ballistics in Italy tried recreating the rockets on a larger scale a few years ago as well, with some success. There were at least a few snub versions of the pistol made, and some select fire versions of both pistol and carbine. At least one pistol was used in combat in Vietnam, and was reportedly effective. They've also been fired underwater. That's all covered in the Small Arms Review report from the early 2000s. Addition: looks like all of the reported Gyrojet problems surfaced. Misfires, variable velocities, sometimes wild inaccuracy, and maximum velocity isn't reached until some distance from the gun. Before which velocity can be very low and the rocket is easily deflected. Even when new, performance of the little Gyrojet rockets was somewhat erratic. I believe it's been determined that the propellent was a single formed grain of Bullseye smokeless powder wrapped in flash paper. There seems to have been another one or two unknown secret components of the ammunition to increase immediate acceleration from the launcher.

Joel is a cool dude. How awesome of him to share that with you guys.

This is by far some of the coolest video i've seen, like those things look like the rockets that come off ships a little burst of speed and then the engines fire and the thing zips off. Thats so cool looking I almost wish all guns were like that just cause gun fights would look sick at night

Matt your videos are muuuuucho fun brother!!! Thanks for the good times! God bless you and yours❤😊🎉 KEEP HAVING FUN😂

If there is more ammo to be had I want to see y'all set something up with the slowmo guys. It would be sick to see what the round does in flight!

As a former missile guy in the army. I’m totally about to nerd out on this hand held missile launcher.

Gyrojet projectiles would be perfect for drones and you could even make a true recoilless system by crimping a venturi nozzle on some suitable thin titanium tubing. But countershot would also work as you usually don't have anything behind the drone.

perfect round to work with the slow mo guys with. this would look insane at 10,000fps

Matt not succumbing to peer pressure at the end by not firing the shot is some true character development!

Joel is a legend . I have always wanted to see a gyrojet fire in person and this was almost as good ! Thanks to Joel and Matt!

The slow motion on them things is so cool

Epic as Always

As a Brit I must quote "Monty Python", are you ready 'And now for something completely different'. What a show we had rockets, squibs, misfires, crouch shots, ricochets, zombie head shots and more. A big thanks to Joel, and everyone there for a great post, thank you.

15:42 I was smiling at the shooting of them until he decided to look in the barrel of the gun for the squib round instantly was like I hope it doesn't jet propel into that guys face glad he's safe love your content keep it coming

im impressed how effective it is. ive never heard of one of these til now but its definitely a cool oddity and i love the idea of rocketed rounds haha

at 22:44 if you go frame by frame you can see uneven jet distribution to the point its got a near 15 degree rise from the barrel. Thats scary.

Gotta be one of the best episodes in recent times. The non stop innuendos, cool interesting gun and chilled guests 🙌🏻

I know they're impractical as all hell, but those gyrojets are just so freaking cool from a technology perspective. Especially when you really think about what they had to work with in the 60's. Awesome content and thank you to Joel for sharing!!

I love the idea of this gun so much

Damn that's cool to see one of these in action. I saw them years ago in Forgotten Firearms but I don't recall him trying them out besides just showing the mechanics behind it. My first thought on how to improve the design would be like how revolvers have the gas shielding (or whatever they actually call them) to protect the user's hands from the debris shooting out the gap. Just little vents on the holdes to direct that pressure front and away from the shooter. edit: Also Mr.Wonderful should definitely make a return. Seems like a legitimately relaxed person

What a badass episode. Joel, Mikey, and Matt were having a “blast”. Especially with those hot loads in the face 😂😂

I like how relaxed these guys are instead of the typical hyped up RU-vidr.

What an insane concept. Would absolutely love to experience that once.

That owner was not trying to fire that super duper suspect round out of the most flawed design i have personally ever seen in a firearm. Dude gave him the first rounds (at $200 a piece) got back about 30 feet, and said "fire away". What an absolutely terrible idea for a firearm, in just about every type of way. The potential for things to go terribly wrong with that thing is also pretty significant. Thank you guys for posting this crazy thing. The history of firearms design is so interesting

I have been to michiana firearms a few times and I actually don't recommend them. They are overpriced and some of the workers are very rude. I went in asking for a good hunting rifle and I had a budget of $1,000. One of the worker get telling me that for that price I'm not able to get a good hunting rifle and that I need to spend like $600 more and get a Benelli Lupo. I told him it was out of my budget and he acted like I didn't know what I was talking about and he kept pushing me to buy the Benelli. It is clear that worker was just trying to get me to purchase from the brand Benelli since Benelli gives the sellers a kickback for pushing their guns.

This is one of the coolest things I've seen on this channel. The slow mo is so sick. Thanks to Joel for showing us this.

Joel is awesome for making this possible!!

Your face on that first shot is priceless.

Joel seems and looks like the super chill, very laid back uncle we all need in our lives. Please bring him bad. BTW... An idea for a future video, you should team up with Scott and play around with his new punt gun!.

Joel seems like just a genuinely really nice guy, would love to see more of his collection

This was a really cool piece of history, the gyrojet is crazy looking nice video

Several years ago I read an article about the GyroJet. The manufacturer of gun(s) was in Northern California. The article listed the company's address and I recognized the street. Between appointments one day I found the building. It was in a typical industrial park, nothing special. I still got a kick finding it.

To Joel: I have ALWAYS wanted to see good quality gyrojer shots, especially in slow mo! Thank you so much for sharing your guns and thia precious ammo with us!!

Joel, we truly appreciate you bringing these out.

The engineering is great. A modern revisit is needed.

I’m a Hoosier n ur follower. Love this for so many reasons

Finding ammo for that would be virtually impossible I'd imagine.

Thanks Joel for the opportunity to see a really cool and unknown to most of us, piece of weapons history. May the force be with you

Firing these reminds me of being in Fiji on a film. My mate bought a heap of professional fireworks off the docks but we needed a mortar to fire them. After a bit of welding we had a hand held cannon. That night at the hotel armed with a face shield, gauntlets and our cannon we set them off. One of the funniest nights of my life!

Thanks Joel!! Super generous of you to share your super awesome ROCKET BULLETS!!!

Its so crazy seeing Mikey working with Matt. I was watching Matt while me and Mikey were in highschool together. Glad that boy is doing well for himself.

Joel, has to be the nicest gun collector of all time! Just coming out to share a piece of his awesome collection, and giving Matt the honors of firing it even before he did. Only a true collector would be able to save such a special piece for such a special occasion.

Joel is an absolute UNIT

May be hard but id like to see you and the Slowmo Guys collab to get super close footage of the actual jet leaving the barrel and picking up rotation.
