That is the most janky but genius idea anyone could come up with

this in essence is a powder assisted ramrod. I like.

The poor man's An 94 ! Amazing ingenuity !

Everyones talking about the ammo but I would love to have that old single shot .410!

Mad respect. This idea seems so crazy to me I would never believe it to work. still in awe

You should be able to "see" the double shot in the audio track. Standard audio capture rate is 44,100 samples per second.

Compression ignition would also be an interesting method for detonating the second/primary charge. As the air in the barrel gets compressed, it also becomes super heated. I wonder if the second primer is even needed for this to still function. I'd be willing to bet a simple pin hole covered with tissue paper acting as the wadding would do the trick.

Ngl, kinda loving the aesthetic of that skeletonized stock on that antique .410

Using a bullet to seal the breach just feels thematically appropriate here. This round is janky as hell, but it works beautifully

Should we tell Ian at forgotten weapons that the Bic-lock gun is real?

Appreciate part two instantly. Thanks

This channel is fast becoming one of my favourites!

a high speed camera would be awesome! maybe a Chronos High Speed Camera would fit the bill? its good value for what you're getting, you should look into it

I wonder if the compression from the bullet moving towards the breech would be high enough and reliable enough to ignite the powder, since its basically acting as a fire piston. Then the second primer could be eliminated.

I once thought about making a type of ammunition that used a friction tube such as used in the early days of breechloading artillery 'vent sealing tubes'. These used a small copper ball between the match composition and the rest of the priming chain. There was a tapered chamber that admitted the flame from the match composition, around the copper ball / tapered annulus into the rest of the powder train. When the main propellant charge turned into gas it hammered the copper ball into the tapered chamber until it sealed. I never got around to this. Never seen anyone make a small arm like this. It would be fun to play with.

It's a mini super slam motar.

I feel like this has potential for 3d printed firearms. In 3d printed firearms, the biggest limiting factor on power is the need for a secure breech lock, that plastics just cannot provide. This thing does not have a breech lock. Theoretically someone could make a full auto assault rifle that uses these cartridges where the only metal part is the barrel.

hey, you can try angling the camera along the assumed trajectory of the round and spread the range from just a few to at least 10 meters to try to get better footage of the round.

To quote Towly from South Park: "I have no idea what's going on right now".

My Italian grandpa has been looking for his shotgun ever since he lost it hunting

Its entirely possible that it lit off prior to the primer detonating on impact as compressing air causes it to heat up. Like those pneumatic/pump fire lighters/strikers, or a diesel engine.

What an absolutely fascinating idea and video ! Love all the work you do, rarely do people on youtube go so in depth about concepts regarding firearms

Instead of a 410 shell you could use a rimfire case which (usually) has a bullet diameter the same as the cartridge diameter. As a bonus you can hit the side of the muzzle with a hammer to fire it instead of sticking a pin over the muzzle as with a centerfire.

everything about this is madness. well done!

Ah, the double-sided bullets from Enter the Gungeon. Excellent.

That's awesome work. Very interesting concepts and well engineered replicas.

What an awesome, creative concept!

Thank you for making these awesome videos!

Great video, keep up the good work!

Depending where you live, I'm pretty sure you can rent high speed cameras, too. Buying one outright would be very expensive, but I suppose if more high speed footage gets you more viewers and support, then maybe it's an investment worth looking into. I definitely recommend renting one to get started, and especially if you don't plan to do many high speed videos. :)

Brilliant Topic! Very good Story-teling right to the point, yet entertaining! You deserve more subs. Cheers, S.

"Borrowed from a made guy!" Best quote ever.

I seriously had my doubts about this working but I'm glad I was wrong

So, to simplify the gun, this works by making the ammo complex and twice as expensive as usual. The inventor must be a government official by now. They know how to claim they have solved a problem and saved money; when they have made it complicated and doubled costs...

Wait, so it worked? That's actually amazing.

What you're doing is awesome

That old shotgun is an absolute beauty!!!

That old 410 is probably worth more than your new one. And never loan something out if they aren't willing to tell you what there doing with it

brilliant exercise, thank you

Get gun Jesus on the phone, this concept is right up his alley

One can build a recoilless rifle: 1. Barrel with both ends open 2. Fire hole or cap nipple in the middle 3. Load one bullet so it doesn't reach the fire hole 4 load powder into end opposite first bullet. 5. Load 2nd bullet to trap powder 6. Ignite powder This results in the bullets being pushed out both ends. If one bullet is heavier it will cause the lighter bullet to traveler faster

Bro this is awesome

This could work maybe is a "backwards g11"where the rotating chamber could be at the muzzle. Perhaps an electronic priming system could be used, like the Remington Etronx and a vent hole in the ballast could maybe divert it out of the way of the actual projectile. Great video man!

Hey!! Don't buy the camera, rent it. Nobody buys cameras unless it's their business to use the cameras. Speaking of people who's business it is to use the cameras, talk to Destin of Smarter Every Day or Gavin/Dan of The SlowMo Guys! Both would most definitely be excited to film this in slow motion, and may even have input on cool stuff you can do with it! Especially Destin! He used to be in weapons R&D for the US Military!

That is some amazing content, goodsir, thank you very much. Maybe you could try sending some of these rounds to Taofleder folks as even though they normally test only shotgun rounds I've seen them do also 9mm, 22lr and 45acp I believe. Maybe they would be willing to do some highspeed recording for you.

Now the real challenge: making a semi auto that uses this ammo 😏

Soooo freaking cool man!! Thank you so much!!

I wonder if (with enough trial and error) a self loading version would be possible. Maybe the hammer could push a cartridge from a magazine into the chamber/muzzle before striking the primer? It would be an extremely simple self loading gun, although you're just replacing a complex firearm with complex ammunition Also having your magazine right next to the muzzle is probably a bad idea. Interesting video nonetheless.

Scary but cool .great vidio

Great video as always my friend! The best high speed camera for your use would be the one used by Jeff on the Taofledermaus channel. It was developed with the goal of bringing high speed photography to the masses. It is a Kronos or Chronos High Speed Camera

What a weird way to double the recoil of a gun :P

😂 I love it, so creative.

"You're not firing the bullet, you're catching it"

I believe, at least in the US, you can rent high speed cameras

Very cool and a clever design. Certainly not practical in the modern day, but it seems like a solution for the muskets of old. It may not be as quick as a bolt or even a break action gun, but it's a lot faster than a traditional musket even with the hand lit fuse.

This is rad

That is a beautiful single shot 410 shotgun.

very clever

if you explore this idea further you'll end up with a full auto bullpup muzzle loader

It looks as though the concept worked. I wonder what a graph of barrel pressure would look like. If the ballast ever stuck it would have been an obstruction. It appears clear that that did not happen though. Another concern would be if the compressive heating of the air could ever ignite the main propellant prematurely. It was an interesting video.

Send that shit to Taofledermaus, they'll test it and make some good highspeed footage

the ballast doesn't need a primmer in a sealed barrel. the heat from the compression is enough for ignition. just like a diesel engine or a fire piston.

Completely insane but very smart

Thats cool!

Awesome!

Very interesting.

so I just stumbled across thischannel and I gotta say it's this idea is amazing... and amazingly unnecessary, however it's seems perfect for what I had in mind for some time and that being a use of fuel for propellant like thermobaric bomb, the obvious problem being mixing fuel with air but in this design is almost given, the cartridge would require some major tweaks, but is great step forward for the concept, I'm aware that such an idea is full of problems and I most defenitly don't know wether fuel can even be a viable propellant in an modern firearm, but still it seems very tempting to use something with higher energy density also nice videos

How about placing a spinning disk in front of the barrel, set it to a known rpm then fire, the disk should have two holes with a spacing that can be used to calculate the delay between the firing.

could it be that you don't need a primer on the second charge since you would get a piston compression heating that would ignite the second charge.

i bet the Slow mo guys would love to help out... maybe once international travel is less restricted?

Should talk with the slowmo guys

I’d love to see this in slow motion!

Bro are those all your c96 .. Thats a nice collection

I think the initial primer should be a side strike primer.

GET THIS MAN A HIGH-SPEED CAMERA

That's pretty bad ass

Why do you need the lower primer? Wouldn't the powder ignite via the diesel principal?

So where can a person pick up one of these junk 410s?

I wonder if you could use compressed air in the barrel as the only source of oxygen?

I agree, a high speed camera would certainly work the best at finding out what is happening. I go a cencept which would be very cool to try; 1charge to rupture a small disposable gas can, and one charge to set off the gas cloud before it goes up in flames. It can be timed to the milisecond with an arduino. The initiators being christmas lights, it can be set off by just the arduino. This could be the cheapest "boom for the buck". A termobaric bomb. I like your concept and it seems to work. Greetings, Jeff

Not sure if you will read this... but, would the powder behind the primary bullet even need a cap of any kind? I would think that the pressure from "ramming" the round backwards would be enough to combust the powder. (Slam Rod Fire Starter) This idea would not need a rear opening to clean the barrel out, and could be rapidly fired (relatively speaking) I could be totally wrong, but... Just had this thought the whole time I was watching your video.

This is fucking amazing.

surely compression ignition has to be concidered?

World's fastest handless/wireless ram rod.

Have you thought about full30 or similar for the content youtube hates?

would it make a difference if the barrel was a vacuum ...?

Yeah, i wouldn't recommend shoulder firing that gun either. There are reasons why the shooter shouldn't want bullets traveling towards themselves. You wouldn't have to get the math very wrong on this for the breach end to explode in your face. Interesting....yes, i just don't get the point.

So if it worked as planned what fell out of the end of the barrel on the table after it was fired and the gun got dislodged from the holder

I'm not sure the primer on the main charge of necessary. As you compress the main charge the shit in the barrel will heat up and likely ignite the main charge. Might be able to make it simpler.

load loaded muzzle loader?

I wonder if Destin from Smarter Every Day would be interested in helping you film it.

Charge Operated Vascilating Ramrod Round. COVRR.

Compression heating would set off the second charge if it wasn't so heavily wrapped.

After watching this a second time, a thought occurred to me. Wouldn't it be easier to use a small packet of liquid engine coolant to create the shaped charge instead of a ballast? Then no deflector is necessary, and you simply need to modify a grill lighter or some other device to allow the gun to function with the pull of an electric trigger.

would this be a machine gun since it fires two bullets per one pull of the trigger?

A shy round, it seems 🤔

You can rent a better high speed camera than you'll ever be able to afford.

What is the point in all of these over complications in a practical application?
