A buddy of mine who used to go metal detecting for Civil War Artifacts, once dug up a perfect specimen of two mini-balls that had hit HEAD ON and fused together. The artifact itself was amazing, but even more amazing was to realize that because both bullets had hit each other perfectly, the two soldiers had LIVED!!! After that fateful shot, it was probably not a good outcome, but at least for that moment in time, they both lived to fight another day!

I notice that both your barrels have right hand twist, so when they are facing each other, the bullets are spinning in opposite directions. If you had one barrel with a left hand twist, both bullets would spin in the same direction. With the rotational energy cancelled out, it seems that it would be much easier for the bullets to fuse on impact.

[@blainetaylor8718]

What a great video and narrative! As an 80 year old physicist with a lifelong interest in ballistics, I have a couple of comments; The muzzle loading rifles of civil war era used a much different rifling twist than modern ammunition. The use of hollow base or "mini Ball" bullets rammed down a bore require a much different idea for stabilization. The lead composition is very, very soft so that the hollow base can expand to fit the bore tightly and engage the rifling without causing so much loading drag. Many of the muskets used in civil war time were smooth bore, without any rifling. Stabilizing the bullets in a smooth bore required a round ball , or in later years a Mini Ball with a hollow base or skirt. Modern air rifles also achieve stabilization partly through the skirt stabilization. If you compute the total energy of a bullet, it is not just "1/2 mv squared" of linear energy, but has a rather large rotational energy due to the rifling twist. In a head on collision, this rotational energy is in opposition for the two bullets, To achieve true linear energy transfer, you would either have to have the two bullets rotating in opposite vector direction, or not rotating at all. For reference, a 45 colt is commonly rifled at a 1 turn every 16 inches, wheras the muzzle loading rifles ranged from smooth bore (no twist) to 1 turn every 5 to 10 feet. My suggestion is to change the rifling to very long twist, in opposition, and use a pure lead bullet if you really want to see a fused bullet. The other factor is velocity. Black powder muskets had a typical velocity of 900 to 1000 feet per second, with a low ballistic coefficient, so they would slow down rapidly. If there were something like 400 yards between the opposing battle lines, the bullets would have been traveling less than half the muzzle velocity at center path collision. You might try to fire a pure lead bullet at a steel plate and determine the amount of deformation of that bullet then take half the linear energy backed out to velocity as a starting point for your powder charge and velocity starting point. Modern large bore pneumatic or air rifles might be an easier and more controllable medium to base your configuration on. Again i want to emphasize what a marvelous presentation you have made!!!

Well thought out guys Thx

[@iq911506]

Regarding the straight lead bullets, it may be worth trying to remove the oxide layer. When the original fusion occurred in the civil war the bullets may have been freshly cast and easier to fuse at lower temperatures. I see this akin to soldering PCBAs where older solder is resistant to melt initially from oxides and a touch of new solder/flux enables it to melt much easier.

[@mycosys]

I think the temperature and shape are the keys - the black powder burns a lot slower and the minie ball is hollow at the back. This means a LOT more time in the long barrel and a lot more surface area to heat. The bullets would have been VASTLY hotter. It also means very little mass at the back of the bullet to continue pushing them together after the initial impact.

[@josephgauthier5018]

Was thinking the same thing. I bet polishing and then stripping off any polishing compound with solvents would help significantly

[@christianellegaard7120]

Get the lead a pure as possible. And then anneal the bullets after casting them. That will make the bullets as soft and malleable as possible. Or maybe use gold.

[@Sembazuru]

Maybe paint a little bit of liquid flux on the tips of both bullets. The heat of impact might be enough to activate the dried flux on impact.

[@Funnyboy2402]

I think you have a to small amount of led for them to fuse together. Bullets today is made to fly as fare and fast as possible. Thinkg they couldn do so much in the old days. So some more soft lead and a bit larger amount of it and you can do it.

Love the engineering that went into this! The fact that so much thought went into replicating what happened in real life speaks to the massive improbability of it happening at all. I imagine each of the soldiers would have been astounded that neither got hit after quite literally shooting the barrel of their gun directly down the barrel of the other. I wonder if the temperature of the bullets at contact have anything to do with it. I can imagine the two soldiers who fired at each other may have been firing a lot already by the time they engaged each other. Perhaps their barrels were already hot, adding some heat to the rounds before they were fired, and maybe that helped them fuse together easier?

So google "Reddit Two collided bullets from the Battle of Gallipoli, 1915-1916" to find the pic. But then I saw it wasn't actually real.

[@007rockford]

first I thought he is taking about that bullet scene only...

[@mxmdabeast6047]

I haven't seen any analysis on it but everytime I saw a photo of those bullets, I assumed it was far more likely one bullet hit a clip/box of bullets and got stuck in one. But, considering the timing involved, I do think you're right about the odds of two bullets hitting with perpendicular paths being extremely low. Though, I think the odds of them fusing would be increased, as far less momentum will be transferred (assuming lower is better).

[@trentsheath7324]

If you look closely at that picture. One bullet had rifling marks, the other does not, indicating that one was never shot. Still pretty cool non the less.

[@BrickTamlandOfficial]

it would be easier to try and hit two arrows perpendicular.

The Safety procedures is great to see. We often get a lot of "don't try this at home" which is valid, but modelling good, conscientious development of safety procedures is something i don't think we get enough of. especially because it can go a long way to demonstrate why it's not something that can be tried at home.

[@user-hu8jx4kq5l]

Amazing Guys and thankyou so much. Great experiment.

[@robfarquharson]

Not sure if you thought about it, but the rotation due to rifling causes the 2 bullets to spin in opposite directions. Maybe the old bullets didn't have rifling, or rifling wasn't standardized and they both ended up spinning the same direction. This would be much more conducive to bonding.

[@magnumpolmatier8184]

They had rifling back then, but it wasn’t omnipresent. I don’t know if it was consistent. Good observation

[@alexanderlohr3917]

This. Great observation!

[@jonathansmith6050]

Especially in the early civil war both sides did still issue some smoothbore (non-rifled) muskets, which would have been firing large spherical balls; for example the .69 caliber Springfield Model 1842, which saw service in the war, fired a solid lead ball of .675 inch diameter; weighing about 30 grams. Or about twice as much lead as the bullets Destin was using. More lead, without opposing rotations, might be enough to make them fuse, especially if it was also a slower collision than Destin's (and given how quickly smoothbore balls lose velocity compared to spin stabilized bullets it might well be a slower collision than even low powder close-range firing can provide).

[@bobdunchad4464]

^^^this. I came to the comments to post this. See if you can get a mirror identical barrel with a left hand twist, or two smooth bores.

[@EarlHayward]

You forgot to mention the speed of the projectiles… In my opinion, that is why some of the shots just essentially exploded… That is, the force of the projectiles was relevant to the experiment… Edit: At around 26:00 they made adjustments to the powder, thus the speed, to address exactly what I was speaking about… These guys are amazing! While I understand physics, machine a lot of my own parts, and design controls using various systems (ESP32, RP2040) I am don’t think I could recreate what they did without a team like they had!

[@brianseaders]

Have you considerd reversing the rifling on one gun so the bulits are rotationally speed matched on impact?

[@theblunderbussbrothers9547]

Was going to say this. There's quite a lot of rotational kinetic energy in exactly opposite directions-that lead is gonna splatter!

[@nopenope8418]

That or use smoothbore barrels, modern tolerances would make them accurate enough at that range for consistant results.

[@TheLastArbiter]

22:03 the way they came to an absolute dead freeze for a moment is absolutely insane… possible since they have almost exactly the same energy… wow it’s like the middle pauses while the rest is still in play

[@0v_x0]

It straight up looks CGI. I'm not saying it was at all, it's just so uncanny to see it actually happen that it feels "off."

[@skie6282]

They needed to have almost the exact same velocity and weight!!

[@CrimFerret]

That's what physics says should happen, but they actually did it, on video. Equal energy from opposite directions and the main pieces just froze in place with zero velocity. That moment is totally poster worthy.

[@kliersheed]

yeah its underrated. better than fusing them IMO.

[@cjod33]

The distance between the ogee(the spot on the projectile that touches the lands) and the Lands( the very beginning of the rifling) effects the accuracy greatly.

If you watched Mythbusters, they did the conservation of momentum trick where the truck moves one way while a ball is shot in the opposite direction at an equal but opposite velocity to the truck, and managed to get a shot where the ball literally did not move horizontally at all before dropping vertically. This is literally on the same level of physics demonstration awesomeness.

[@jacklinde7568]

Destin, have you thought about contacting a material specialist to figure out the conditions needed to get the bullets to mushroom and fuse instead of crystalizing and shattering?

[@SeanBZA]

Need old lead, no alloying additives like antimony and calcium, all added to make the lead a harder alloy. Old lead has a lot of silver in it, along with zinc, which makes for a soft alloy that will readily bond with cold welding.

[@ElboxD]

@@SeanBZA that's so cool! Any source I can learn more about this?

No you just need old bullets…. The new bullets are made with a different type of alloy you don’t need a specialist to figure that out…

[@WitherShield]

Could you try and catch the bullets in a medium just as they meet. You could try to use a slab of ballistic gel that you can cut down to vary the length, therefore controlling how much the bullets slow down before impact. It could have an added bonus of catching the fragments mid explosion like what you did with the prince ruperts drops.

[@aserta]

BG does affect the path of the bullet. That's adding yet another level of complication on top of the existing ones. Not the right way.

[@WitherShield]

@@aserta Very true! although from other videos I've seen bullets don't seem to deviate from their course too much, especially since the gel won't need to be too thick just a couple of centimetres - enough to just slow the bullets, not stop them.

[@MicahScottPnD]

I'm thinking of the fusion of the bullets that caused this project, is it possible they collided in a medium of some sort? A wooden wall, a tree, something like that? The fusion in the wallet suggests that quite loudly to me. I KNOW someone knows more than I do on this matter. Is it known where/how the original fused bullets were found?

[@SyntheticFuture]

@@MicahScottPnD pretty sure they used softer (more pure?) led back in the day and those muzzle loaders shot a lot slower than modern guns (they didn't have the tolerances to have a good seal and the black powder wwas pretty course and unrefined.). Add to that some distance and you'd have two pretty slow soft things that could merge. The odds of that happening are insanely small though... Your theory is also a possibility but I would expect them to still be stuck inside that medium if that happened.

[@realifethunder]

Destin, the first thing I thought was that civil war era bullets were almost pure lead, which has a brinell hardness of around 5. Most bullet manufacturers are producing rounds with a brinell hardness of around 18-22. This makes them much more brittle. I have some pure lead laying around and could cast you some bullets with varying hardness if you would like to test that out.

[@ThisRastafarian]

Between the frames of 22:00 and 22:03 right before the bullets meet, the forward momentum force causes a dent on the round. You can see it slowly forming right as they get close to each other.

Dance of the bullets - Beautiful and Deadly

[@titanuranus]

Modern cast lead projectiles typically have antimony in them, which increases the "hardness" of the bullet (this makes for a better hunting bullet). You can make 100% lead projectiles using a bullet casting tool, check with some of your reloading buddies and find out who is rolling their own (so to speak). They can probably easily hook you up.

[@tde1964]

Pure lead bullets will require to clean the barrel after each shot as they will fill the rifling and lead to inconsistent ballistics. I also wonder if the bullets would fuse better with a bigger caliber. Last but not least, the offset of the barrels is making the fusing more difficult, but the only option to protect the guns would be for each one to shoot through the hole of a rotating disk. It’s quite difficult to synch, but a good challenge for perfectionists!

[@spvillano]

@@tde1964 you can avoid them shooting each other by a longer flight distance, allowing drop to handle the matter for you, but also increasing the precision of the build to allow much greater precision in adjusting the aim to cover the greater range. That said, one wouldn't have to clean the barrel after each shot, but they'd need much more frequent cleaning. One can offset the higher velocity and fouling issue by using a slightly larger bore. Lower friction and cutting by the rifling, gas leakage lowering pressure and hence, velocity, downside is lower accuracy. Chroming the barrel also would lower fouling.

[@ComicalCowboy1911]

This exactly! Need 100 percent lead bullets for any chance of fusion. And if velocities are low enough, leading in the barrel won’t be an issue.

[@georgegordonbrown9522]

What is the "hardness"?

[@LeNomEstYves]

​@@georgegordonbrown9522Think of it like the "brittleness" during impact. Softer bullets would be less brittle so less prone to shattering.
