Smoothbore Weapons Solutions

[@Karza_357]

I think you were too harsh on the 3rd design. After leaving the barrel the bullet oscillates couple of times before stabilizing properly.

[@CausticSpace]

I would disagree, you might as well have spent the time rifling the barrel.

[@JinxBlitz]

​@@CausticSpacehuh?

[@ManicObsevations]

Wasn't the entire design rifling what the barrel sits on so it spins? Which then spins the projectile? I mean he did say the barrel was short

[@jchoneandonly]

Except the third design is far more complicated with more failure points.

[@ChaosEldritchPrince007]

Expand the tube slightly + add more riflings/groves so the project can rotate more before exiting the barrel + small riflings on the project's base for it to track and rotate on and perhaps it'll perform slightly better.

[@JWQweqOPDH]

For something like a shotgun slug, the simplest way to achieve stability is to make the front denser and the rear less dense, either with a lighter metal or a hollowed out rear.

[@robotpotato6892]

maybe this can work by making the back of the projectile hollow.

[@johnElden8760]

Back is rear​@@robotpotato6892

[@classifiedad1]

Like a shuttlecock?

[@JWQweqOPDH]

@@classifiedad1 Basically, yes.

[@bondrewdthelordofdawn3744]

There is explosive ammo for aa12 that exactly look like the second prototype

[@pearldragonz]

Gunsmith here. Would be interesting to see these concepts with lead or copper being incorporated into the design and launched at a higher velocity. Maybe hollow out the front to place a metal slug that would add mass to improve stabilization and energy retention. Possibly even adjust the fin design so that it has a slight twist to the edge that will induce a spin. Ignore all this though if these are tests on less than lethal concepts meant to be fired out of a Nerf gun.

[@Fortified-Star-Margarine]

With the third one, you just made a rifled cannon.

Theres a reason why modern tanks rounds are fin stabilized, you showed why here

[@GrinXpedia]

[@amitaimedan]

I believe that subsonic behavior is a lot different the supersonic speed.

[@DVXDemetrivs]

it is

[@joearledge1]

The mass, velocity, and center of gravity matter a ton! Not just the profile. Dunno what you're background is, but for projectiles to be drag stabilized, the weight needs to be distributed like a shuttle cock, or a dart, or an arrow. Front heavy as hell, and sufficient velocity

[@barraktu]

I was under the impression that diabolo shaped pellets were the best projectile out of a smooth barrel without the added complexity of having to deploy fins. Basically just a heavy tip and a hollow base which forces it to orient itself in the direction its moving.

[@intellectualiconoclasm3264]

The miniball requires a hollow base for propper weight distribution. I bet it'd work just fine if it had one. Thank you for how you shared your R&D with us.

[@PlasmaFreak]

Have you considered using a glow in the dark filament round with a UV led at the barrels start to produce a tracer round like affect? I think a 3D printed tracer round would be interesting indeed

[@indyjons321]

Overly complicated rifling. lol I love this!

[@michaelhill6451]

If you want it to be stable, the center of mass needs to be towards the nose. In shotgun slugs, this is accomplished by having a solid front and hollow rear (which also helps to expand the skirt of the projectile so it seals against the barrel).

[@templarsjustice4956]

I really love watching these and find them extremely intriguing

[@ge0arc244]

Great TESTING of Stabilization without rifling. #rd test would have gone better with higher velocity to impart more spin. The fin stabilized solution works well also.

[@Fightre_Flighte]

>smooth bore. >Proceeds to make a more complex version of a rifled barrel. Makes sense, I guess. Two big points that might be holding you back: 1. Weight the nose, at least slightly. Cam also be achieved by hollowing the tail of the round, you wanna move center of mass closer to center of pressure, and make center of lift (or drag or whatever) further behind center of mass. 2. Sand. Your. Prints. I know, we love making quick prints and full sending it off the bed. Don't, though. One of the reasons that the first one might've resulted that way is because *your print induces a lot of skin drag, and turbulence on its own.* Plus, 3D printers were intended to be a quick mock up to be sanded before display or use anyways. Print in place designs, and settings adjustment make thos /avoidable/ but not entirely to be gone without at all times. Keep at it. You'll come up with something fantastic.

[@God-of-canine]

We use APFSDS now because it does more damage and is more effective and can be put in a wider range of barrels. And we use smoothbore because the normal ones would make the APFSDS spin, that is not good because it would get set off course. The APFSDS. Is clearly the better option.

[@malakiblunt]

the spinning barrel is hilarious ! 😂🤣😅 - though its not unlike the spinning sleeves they add to apfsds rounds to fire them from riffled guns

[@ScoutSniper3124]

Not enough to just have fins, they should be designed in such a way as to impart a stabilizing spin on the projectile.

[@chrisbacon3071]

The second design is the best because the Soviet 125 is smooth bore and can fire gun launched ATGMs that have the same shape as the fins you designed!

[@ShiroiShinjuDC5]

I would like to see the rounds leaving the barrel especially the fsds but definitely needs better weight distribution to make the shape more effective

[@livenishikireaction]

in Russia, we put rifling not on inside of barrel, but on outside.

[@thenamestails7152]

I think flechettes need more attention. They're relatively cheap, and very stable (basically, a small arrow - even the name says so: Flechette means "Little arrow " in Italian)

[@thedesignerblacksmith5953]

I watched a couple of video on your channel and thought "maybe this guy is just another guy doing some testing". You know, like those guys who make simulation video. It can be quite helpful sometimes. But then I started to think again. What is your intention here? It looks mostly like something you research and makes just for fun. Sure, something can be useful, like the structure of the bullet so it doesn't break in contact. But it still looks like above. Because there is something called "swaging bullet", which use ammo case as the jacket for bullet. Many bullet cases have rim, it can help with the use drag solution you mentioned. Jacketed bullet mostly help with rifled barrel, but with some design solution like that, I think it also helps with your idea of smoothbore barrel bullet. Plus the cheap price of the ammo cases used.

[@jordanhorst6]

A Helical hexagonal bore and matching Helical hexagonal projectile will create spin stabilization. Without the need for the barrel to spin. I'm not sure about long distance ballistics of a helical projectile though. I've seen a black powder rifle that used a helical barrel and helical sabot to spin a steel projectile effectively. That was a few year ago though.

[@hrishikeshaggrawal]

your spinning barrel mechanism uses rifling which is what smooth bore originally tries to get rid of anyway to simplify production. instead, make the projectile have fins that are then directly present in the barrel as a straight line

[@drowie_]

If you create a powder version of the second solution, then you can use flammable paper to contain the wings, when fired it will simply burn

[@Aki8w8]

What about using a weighted tip? For instance: Using a hollow tip and putting lead shot in it

[@introver4739]

love your content man, so please keep em' coming

[@user-wx7pc4in2b]

u are the best solution channel I ever see

[@fujiwaraofmokou]

With the second design you basically made a hunting arrow

[@liquidmech1727]

that last one may not be super good but holy shit thats a cool design, im putting that into my brain for later

[@ZenithPeak1]

I’m assuming this is simulating tanks, and they already have it covered, rocket ammo that propels itself, and with the finned rounds, they use what’s called a “sabot” which keeps the rounds stable while inside of the tank barrel as they travel down it, then, using drag, the sabots get caught by the wind and open very quickly, letting the fin stabilized round open its fins and go the rest of the way with very minimal velocity lost

[@Levguy140]

Now *this* is why I want a 3d printer

[@lordtomlluckrahthegreat9014]

Rounder nose shapes are better aerodynamically for subsonic flights, which is why most pistol rounds are either rounded or flat. It's also mostly the reason water drops have that sort of shape. You should try it again with bullets that are less pointy.

[@formdoggie5]

Your proximity is causing issues with the results. The stabilization methods you are using correct themselves over time. Think of it like an arrow from a bow with flights. Spin from rifling is totally different as its correction occurs initially and then falls off as the round loses energy, or imparts too much spin, causing leverage and thus, curvature in flight, usually biased in one direction. These are all essentially drag based designs, so they need drag to function. The more they are exposed to, the more accurate they become. However, drag operation also means loss of performance over distance due to lower ballistic coefficient, as drag causes loss of energy over distance. Both of their merits -- both have their downsides. Pick the one that works best for the shooting you are trying to do.

[@sliceofbread2611]

we need to sponsor you a slowmotion camera

[@CrockedAardvark]

The second one is basically an apfds but with removable fins so it is an apfsdsdf ( armor piercing fin stabilized discarding sabot discarding fin

[@Epieic3]

you should use a normal round as a control to make sure these actually had stabalizing effects

[@Holysoup-d1b]

I HAVE AN IDEA :) MAKE THE BARREL WITH RIDGES AND MAKE THE BULLET SPIN MORE ACCURATE FIRE AND POWERFUL:)

[@dragoro3033]

wait, 4th round with rifling built into the round itself, not the barrel. Still get smooth bore, but now your round will spin and stabilize itself? Just thinking about the problem, maybe escaping gasses though would spin the bullet backwards while in air flight the passes air would counter rotate losing stability? maybe a plug to keep expanding gasses from spinning, but this leads me to think it won't spin enough by exit and you cannot reliably keep it straight from the get-go. Thoughts. Maybe you can create basically a Tesla valve that allows gasses to spin one way and after ejection from barrel, the air will block that route and keep the round spinning in the correct orientation. This also can provide a drag like your first design.

[@183.84u]

My biggest concern for the third design is if this is concerning tanks, like how the British army moved to a smooth bore cannon on the newest designs of their Challenger 120mm is concerning heat rounds and other chemical explosive rounds, which are less effective if spun. Unless the third design has a way to disable the rotation then it causes the same issue. An interesting design to me is that of the Foster slugs which are rifled rounds. I might be completely wrong and anyone feel free to correct me if I have made a mistake.

[@183.84u]

Also I would just like to mention I love your content and I wish for you to continue with your research.

[@jonathanrogers9961]

design 1, the grooves are designed to hold lubrication, that is not intended to great drag for stabilization. Also, typically that design had a hollow base. design 2, yes we know fin stabilization works. Last design, its hexagonal rifling, but doing it the hard way. When trying to spin stabilize a projectile the speed of the projectile effects the stability as well. You could fix the stability by shortening the projectile, increasing the speed of the projectile, or increasing he rate of spin of the projectile, or any combination of those 3.

[@LottoDub720]

Most designs require higher velocities(typically 1000 fps or more) for any part of the design to properly be effected by the air and drag to stablize the bullet.

[@LottoDub720]

Because bullets are metal and have so much mass comparitively to the mass and density of which it's traveling through(the air) that it needs a lot of drag to effect the bullet.

[@LottoDub720]

All bullets require a balance between mass and aerodynamics to work properly and what you're intending for it to do

[@nekogirl7468]

The 3rd option is the most overengineered thing i have ever seen. Smoothbore? Just add another rifled barrel inside it and make it rotate! Props for the idea though. Pretty hard to imagine and make something like that.

[@HondaCivicvti-l]

For the finned design, perhaps it would be even more stable if the fins deployed backwards, like a snakeye bomb

[@johnaldag3645]

As others have pointed out, the spinning barrel is just rifling with extra steps

[@troyonik]

Time to use this for my Science experiment

[@vijaymoudgalya9915]

This, ladies and gentlemen, is why we gave up on solid shot and heat in favour or sabots. Its simply the superior shell

[@Chleosl]

HEATFS: Imma show up and make it clarify who is the best.

[@robertszakal]

Just an idea, but the projectile rotation could be achieved with spinning wheels (like in most electric nerf guns). Just tilt them to the opposite direction

[@TheArklyte]

I may be a bit of an ass for saying that, but usually one of the main sources of the progress in firearms is minituarization of solitions ALREADY found by artillery. So, you know, APFSDS aka "flechettes", rocket assisted munitions aka "gyrojet" and so on 😅

[@MilleniumFDH]

Bro mistook Walmart security cam for slow motion camera 💀

[@Drink4Exp]

You almost had it with the second. Look into tank APFSDS projectiles to see how fins can work.

[@jameslogie4342]

I could tell the first one wouldn’t work. Fins stabilize by creating drag on the back of the projectile, reorienting it if it tilts, but with the first one, the grooves don’t make a significant change to drag when the projectile tilts.

[@firstletterofthealphabet7308]

Tip for shooting slow-mo: give it more light! Since the camera shoots at a constant framerate in slow-mo, darker shots causes the camera shutter to need to be open for longer per frame, causing motion blur. More light can increase shutter speed, and reduce motion blur.

[@СНІМР]

might help to add some lead shot in the front, add some weight, improve accuracy without any large feats of engineering.

[@resenese573]

Those grooves in the first mini ball are for to hold lubricant for muzzle loading

[@joearledge1]

Nope... the original designer actually designed the grooves to help stabilize it, as depicted conceptually in the beginning of the video. If you don't believe me, you can go read the original 1850's patents yourself

[@dorcie]

2nd one is pretty much a FSDS round but smaller

[@craigthemonke794]

I know that there are rifled shotgun slugs for smoothbore shotguns for slightly more accurate shots.

[@jeffreykoski2746]

Very nice. I look forward to your videos.

[@dankdaze42069]

Second one would make a great bullet projectile😅

[@randomargument972]

Another solution to consider: Discarding Sabot Finned Projectile, just like APFSDS in tanks

[@hiiamnick1992]

What about using fins and a weighted tip? not weighted per se but using 100% infil in the tip and just 5% infill on the tail.

[@rags417]

Try the Gyrojet solution - ported exhausts placed around the projectile and filled with propellant. Supposedly it did not fare very well but produced nearly zero recoil and zero report on firing, some used as sniper weapons in Vietnam.

[@God-of-canine]

I like that idea.

[@malakiblunt]

try a diabolo design with hollow tail

[@joearledge1]

Yeah that's a pretty proven winner, pellet gun to 10ga, diabolo is the easy button

[@Eddardstark9308]

Unfortunately I think the only solution is to throw out the spinning projectile idea entirely and focus on a flechette like design that utilizes a weighted tip with stabilizing fins that can carry the projectile farther and make it more deadly than a conventional smooth bore round and with less trouble “crafting” it

[@ohu1115]

If you would have 3d printed it in a different orientation, the bullets would have flown way better(print everything on its side, not standing up)

[@andrewyoonhobai8453]

what if the barrel of the gun was already rifled would the grooves in #1 actually complement the rifling? Speed and velocity matter with certain masses.

[@CaptainPrincess]

what Im wondering is what is the benefit of a smoothbore weapon that necessitates developing ammunition with its own accuracy measaures like I know next to nothing about guns so Im asking why even put any energy into this instead of just rifling all weapons
