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!!!

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.

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]

[@jonathan_60503]

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).

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!

Though, I think the odds of them fusing would be increased, as far less momentum will be transferred (assuming lower is better).

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.

Could you try and catch the bullets in a medium just as they meet.

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?

@@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.).

for the follow up, grab a metallurgist that knows a good bit about lead and softer metals. could the civil war lead have had impurities that we don't have in today's alloys? or are modern alloys more brittle due to mixing with copper, tin and antimony to provide corrosion resistance? Would be some really great science content!

My thought exactly. Although wrt oxidation the museum display would keep it in a very stable, if not inert, environment. There is a similar exhibit purportedly from the WW1 Gallipoli campaign of 2 bullets that intersected and fused into a cross.

[@13kire]

I believe antimony is alloyed with lead to make it harder. I imagine harder would mean more brittle and cause the bullets to fragment this way. Also, the softer the bullet the more drag it will have in the barrel causing it to slow even further. So I think bullet alloy is probably the key to success here. I'm glad you have the dream team to make the design and safety for these videos possible. I'm excited to see you guys manage to fuse some bullets!

Black powder has a significantly slower burner time which will reduce velocity while still having enough gas expansion to get the projectile to clear the barrel. These are 2 things worth considering and experimenting with
