Top 3 Weirdest Non-Conventional Ammunition Ever Developed

Top 3 Weirdest Non-Conventional Ammunition Ever Developed

In this video I’m exploring the technology and science of non-conventional ammunition, including caseless rounds and telescoped ammunition, together with a little bit of history. I also made some didactic models to easily show what each technology looks like, and to highlight the advantages and disadvantages of each solution.

    Brass cased ammunition is just too superior in too many ways to be replaced. The greatest feature is the case’s resilience to weather, climate, and contamination.

    Bakelite Cartridge Ammunition
    Caseless Ammunition

    for telescoped polymer, why not make your moving chamber be like a gatling style rotating block, with pistons that are moved by a cam as the block rotates. Those pistons would handle both the extraction and the loading. Possibly the same way as your animation, but with the whole mechanism rotating around in one direction, instead of your design with partial rotation in one direction, stopping for a piston, and then rotating back the other way.

    I really appreciate your approach and deep analysis. You make terrific videos. Would you consider doing a video on electronically configured/initiated firearms?. The Metal Storm is one example I know of.

    check out vice news covering the first 3d printed gun shooting contest [by are we cool yet/awcy]. or somewhere else if they have better footage. they have fully 3d printed guns. fully functional!

    WHAIT DID I JUST SAW A 4 MM BLACK POWDER IGNITION CAP IN TOP NOTCH AMMO FROM NOBEL // at 7 17 //specificly //if so damn we /as humans are still stupid as fuck // i admit might just be a 18 80 black powder cap is top of the top for 2050 machine gun ammo ,,but i doubt /lol /for a few shoot test ok but to go 120 back ,, wheel lock would be a way to ignite a caseless ammo ni strike neaded ,, so why not // alarm wind clock mehanism /china /are working ok and cheap //so f install// lololo

    Give me a pistol

  8. Mr D on October 28, 2021 at 8:44 pm

    Why doesn`t make anyone a hand or shoulder fired gun on the basis of shaped charges?
    If the chamber is strong enough you could put a coin shaped copper plate in front of the charge (whatever it is).
    The question is though how to start the explosion. This might even make the rifleing or the whole conventionel barrel obsolete.
    A other idea would be a rifle that shoots its ammo like a mortar.

  9. Tomartyr on October 28, 2021 at 8:45 pm

    Why didn’t they just make super fat bottlenecked conventional bullets instead of the C shaped one?

  10. Gabriel Vallee on October 28, 2021 at 8:45 pm

    ok, even without demo it’s very entertaining in a very nerdy way!

  11. Deus Vult Infidel _Templar4554 on October 28, 2021 at 8:46 pm

    Is a musket unconventional

  12. Maximilian Montserrat on October 28, 2021 at 8:47 pm

    Are there any gaseous propellants that might be suitable for firearms? Wouldn’t necessarily have to include an oxidizer but of course that would be another design consideration. Combined with electric ignition it could open up a lot of options.

  13. Ted Archer on October 28, 2021 at 8:50 pm

    I have an idea how to convert an ar-15 into firing telescoped partially burning case ammunition

  14. Moonlight Hollow on October 28, 2021 at 8:50 pm

    The up-and-down action has been successfully implemented before too on Madsen weapons. The 1888/1896 self loading rifle and the Madsen MG. Forgotten Weapons had some great videos covering them. It doesn’t work exactly the same and still requires an ejector, but it could be inspiration for how something like that might work mechanically.

  15. Josef M. Pjess on October 28, 2021 at 8:51 pm

    Dear Smart Boy,
    Can you slow down a bit?
    It is rather difficult to follow your machine-gun rate of speech. I truly believe you have a great knowledge, yet I am missing quite a lot of what you say.
    Wish you all the best, but please, take some Ritalin before making next movie..

  16. Rolly Herrera on October 28, 2021 at 8:53 pm

    Uh, people are making railguns now bro?? Gunpowder is yesterday…

  17. Brandon Ford on October 28, 2021 at 8:54 pm

    Suppose there are two chambers that spin around an axis in one direction so that when one is fired the gas is used to to push the round and eject the spent chamber in the chamber that didnt just fire

  18. Earl Rissel on October 28, 2021 at 8:56 pm

    I actually have one of the folded case polymer rounds that were given out at a firearms show by a manufacturer representative.

  19. That Guy over there on October 28, 2021 at 8:57 pm

    WAIT it’s a year later but, what if you made a caseless cartrage out of perforated Cordite. Idk if it is susceptible to moisture or not but it seems like a viable means of making some moderately durable, almost plastic like, ammunition which gets burned up completely leaving nothing to eject.

  20. [A*K] Panther on October 28, 2021 at 8:58 pm

    gauss rounds are caseless ammo

  21. Shannon Lewis on October 28, 2021 at 8:58 pm

    Now I do

  22. Micho Micho on October 28, 2021 at 8:59 pm

    lol nitrocelulose is no only or 1 of 100 ,,more 1000 propelants that can be used from liquid to solid 1 ,2 ,3 component heat ignited or friction etc

  23. yetisuncle on October 28, 2021 at 9:00 pm

    you dont need a ‘"liscence" to build these guns. not in America. you cn legally make any gun you want. and very often people do. you can order pre made recievers and all the parts that should go with it. or you can go to the hardware store and buy all the parts yourself. or even 3d print a gun of any design. and alot of people do just that.

  24. Stephen Gardiner on October 28, 2021 at 9:02 pm

    I believe that in the latter stages of WWII, Germany was working on caseless ammo.

  25. sylumgand on October 28, 2021 at 9:03 pm

    So to shed weight from ammo, you want to add complexity and weight to the firearm. There’s a great phrase that describes this issue, "If it isnt broke, DONT fix it."

  26. Victoria Evelyn on October 28, 2021 at 9:03 pm

    I really like the tround I think that could work if it had more time on it it would be a good machine gun mechanism

  27. Ted Archer on October 28, 2021 at 9:03 pm

    First gun to use case telescoped ammunition was russian Nagant revolver, it remained in service till.1950s

  28. Johnny Lopez on October 28, 2021 at 9:06 pm

    Wild video

  29. Corey on October 28, 2021 at 9:06 pm

    Please stop talking about forgotten weapons, your channel is way better. Ian just happen to be the first, but my no means is the best. Frankly I can’t stand his videos.

  30. Daniel E. Smith on October 28, 2021 at 9:08 pm

    Interesting video.
    Could you sell me a couple of inert samples of these? Really just the right angle ones. I collect ammunition and live examples of those are way out of my price range.
    Thank you for your consideration.

  31. BlazingHand on October 28, 2021 at 9:09 pm

    Italian ammo maker be like: EXPLOSIVE PASTA

  32. EanSeki Travis Berry on October 28, 2021 at 9:10 pm

    The caseless idea could work. Casting the round like before but marginally thinner then applying a coat of more thermally stable compound on the outside. Like a case, but with the idea of the less stable interior’s ignition consuming the casing, with the only spent material from the chamber needing to be maybe the primer cap. There was also electronic guns that stored all the rounds of the weapon within the barrel. Some crazy mounted weapons containing hundreds of those tubes firing off thousands of rounds in a mere second layering down an artillery like hail of bullets.

  33. Sam Jenny on October 28, 2021 at 9:11 pm

    What about the daisy vl

  34. Daniel Escobar on October 28, 2021 at 9:19 pm

    Did your 223 case say 3M on the back? what is your locale? love your channel thank you sir

  35. JLoy on October 28, 2021 at 9:19 pm

    Caseless ammo… first gen cannons, mussel loader

  36. Lonely Lobo on October 28, 2021 at 9:19 pm

    right on my birthday :))))

  37. Schoen Perkins on October 28, 2021 at 9:20 pm

    Just hurry up with those rail guns so we can stop using traditional cases

  38. Grim on October 28, 2021 at 9:20 pm

    Maybe if new materials become available it will have more promise. A cartridge made out of graphene for example. Strong and would also burn up when fired.

  39. luderick wong on October 28, 2021 at 9:21 pm

    caseless ammo is not dead, yet. if you consider naval gun, tank gun and artillery as a "gun" instead of using the meaning of cannon. of cause they fire in different concepts of handguns and rifle.

    by the way, do your challenge restrict which type of powder? burning speed and chamber pressure can be a issue if use wrong type of powder. the other major issue probably will be the primer case, it is difficult to ensure it will go out the barrel 100% every single time. which you may need a special shape bolt to execute the firing process. and i instinctly think of using liquid propellant ignite by electricity. will this count as well?

  40. William on October 28, 2021 at 9:22 pm

    I’m curious how the folding ammo would be fed by a magazine

  41. Micho Micho on October 28, 2021 at 9:23 pm


  42. Quhark Atkali on October 28, 2021 at 9:26 pm

    did someone try making a cartridge which has a case like a discarding sabot and shoots out of the barrel like a rocket then the case just drops off essentially making it caseless?

  43. Tom Thumb on October 28, 2021 at 9:27 pm

    Poly cased ammo flat out rocks, but the price…ouch!

  44. John Gavin on October 28, 2021 at 9:27 pm

    I liked and sub’d as soon as you mentioned the licensing. I would enjoy watching this a lot.

  45. Micho Micho on October 28, 2021 at 9:29 pm

    gyros suck seen 3 hits all did brake glass jar but no plank behind so 22 lr any day ,, go f you go illegal lol we pay so you have fun fireing few shoots// shoot and they are gone // never existed it was foto joke etc ,,pussy

  46. jan piet on October 28, 2021 at 9:30 pm

    I am not an expert on guns but for the challenge at the end, I think the best way is to have a Vulcan-like barrel system with on each barrel at the different rotations the different steps it needs to go through to fire. the steps will be:
    placing a bullet(in a belt) in front of the barrel
    have a steel rod push the bullet out of the belt into the barrel
    having the back tip of the barrel heated up (key here is that the ammunition needs a starter igniter with low combustion temperature that ignites the main propellant)
    (water) cooling the barrel
    the steel rod pushing down will be on a rail where it is forced to move with the barrels and the rails go to the back of the gun in the rotation where the pushing-down state is
    the more barrels are on the gun de more space will be there to have other mechanical parts and it will increase the fire rate

    I actually don’t know, has there ever been made an water-cooled gun?

  47. zeitgeist888 on October 28, 2021 at 9:31 pm

    I just found your channel and am really impressed with the detail and quality of information. I’m watching many videos you’ve done so far. I wonder if you could cover the Metal Storm concept as originally developed in Australia. How it functions and fires as well as design of barrels, electronic firing system, pressures and velocities. This seems like what you are looking at with caseless ammunition fired from a barrel only open on one end. It also has a high rate of fire when rounds are stacked within the barrel.

  48. Mr Straw on October 28, 2021 at 9:32 pm

    Pin fire?

  49. Paul Kersey on October 28, 2021 at 9:32 pm

    How about loading a 12g shot shell with sugar rocket fuel mix ! Potassium nitrate aka KNO3 65% and fine powdered sugar 35% . See TKOR channel for exact mix.

  50. Ammo reloading for beginners on October 28, 2021 at 9:32 pm

    You should come to Texas 😁. You speak out language well, and our leaders just made Texas made suppressors legal like buying a magazine. LOL other States are cracking down on law abiding folks, my state’s deputizing anyone who can buy a gun legally with a background check. Your channel expresses common sense, knowledgeable understanding and I have noticed you emphasizing safety. In Texas we say the 1st 3 rules of gun ownership is safety, safety, safety… Then muzzle discipline and trigger discipline. Enjoying your content my friend! I hope you can get whatever you need in the way of licensing to allow you to provide more
