Thank you for doing these tests. The numbers are very close to what I expected from a good slinger, though I'm surprised by how relatively little kinetic energy increases with projectile mass. 133-160 J with 50-60g stones suggests how effective ancient slingers with lead bullets must have been. That's as much energy as a warbow arrow, & potentially concentrated on a relatively narrow point.
An element of it could be the sling, in that the 41” does not have an optimal grip for slinging heavy projectiles. I recon on solid ground and with another sling, I could probably get 300J. I’m also a relatively small man (under 140lb) so someone larger could be stronger and utilise a longer powerstroke, and achieve more.
You have to remember that energy from speed increases exponentially while energy from mass increases linearly. Also while big projectiles don't see a massive energy increase there is a huge momentum increase meaning that it's a lot harder to slow the projectile down with armour or bone.
Thank you! Glad you enjoyed. If you're new to slings, I recommend practicing with shorter slings and working up, as long slings are particularly easy to send a stone fast and far, in a direction it shouldn’t.
I am discovering these videos just now, but I was thinking the exact same thing! The sling is likely no match for the longbow, but likely comparable or even stronger than shortbows.
@@robertbrun Actually with bows flight shooting for distance it's actually the other way around with the short Turkish bows and light arrows out shooting an English longbow, however the longbow will shoot heavy arrows much better making more power and having better penetration.

Great stuff! I really liked those big ones at the end. 👍 The spot looks absolutely perfect for that. Other than the unsure footing that has been mentioned.
just realized you slung the same speed as world record baseball throw (The fastest baseball pitch is 105.1 mph (169.14 km/h) and was thrown by Aroldis Chapman (Cuba) _142 and 149 g ball)
Yes, now imagine them skilfully using a sling. Immense power. Barehand puts a lot of strain on the arm, and throwing that fast can only be down a handful of times here and there to prevent injury. I could easily sling that same power all day no problem. The sling is smooth and very low strain on the body, with good technique.
This is some amazing stuff. Hopefully you get to try your hands at getting velocity readings with lead, as I'd be interested to know if you can get increased release velocities. Would be interesting to see if there is a noticeable difference.
I do have a set of 85g bullets, which I intend to test at some point. I wouldn’t expect to get any greater speeds though, since the difference in drag between lead and stone during the powerstroke is likely negligible.
@@Archaic-Arms Possibly. I swear whenever I sling with lead, It somehow feels like I'm just magically throwing faster... but that's probably just because the trajectories are just so much smoother and flatter with lead that It makes me think that I'm throwing faster!
@@thejackinati2759 I had one recent experience with lead. I had a few throws around 360-380m (judging by the distance of the splashes from the other side of a river, at 400m), but they felt slow. Mostly because they were a bit on the light side (45g) and I didn't get a hold of them. I could feel they weren't good throws (probably tried too hard). But there was one that I did get a hold of at the very end of my session. I don't know where it went, but by the feel and the look of the trajectory at the beginning, it cleared 400m, maybe further. I don't know if it was much faster. If it was faster, maybe by 1 m/s or two. The key to getting faster with lead, imo, is to get a specialized sling just for lead. Zero wasted drag on a larger pouch. Then I'd imagine another 1 or 2 m/s is possible. My best ever was 80 m/s with a 25-30g stone. And I've done 77 m/s with a 45g stone. ... so, not numbers like AA yet, but I'm working on it! But with a specialized sling and 40g glands, I think 85 m/s is possible for AA or myself.
I'm just getting this strange vibe that I really, really wouldn't want to be hit by any of these. I imagine this was no less terrifying in the ancient era than a gun is today
Hi, I've been slinging for awhile now, I use two techniques. First like yours, baeleric, then I do one like a tennis serve, hell of alot more power and distance. When bringing the weight down in an arc, if I keep it straight I get back spin, off at an angle either way and get spin like shanking a golf ball. At 54 years old out of shape, a 3 ounce sinker goes around 250m. Love these things. Forgot to mention my slinging length folded is around 45cm and made from paracord
So, just as with bows, for any given sling, as the projectile gets heavier, the launch velocity decreases but the kinetic energy increases. If you're going to be doing a lot of throwing, particularly of heavy projectiles, make sure you do targeted strength training and stretching of your rotator cuff muscles so you avoid injury. Overdoing it with throwing is a good way to get peripheral nerve entrapment, and believe me, that's something you definitely want to avoid.
Apparently I had a knack for Javelin in middle school, so yes I’d be interested in doing some tests with them as well! I also have a plumbata, the correct weight too.
180 joules of power is equivalent to the power generated from a .22 caliber round. By comparison a 9mm round is about 480-500 joules. Pretty good! Plenty of .22s have killed people. So a sling definitely has the power to be deadly.
Momentum is a very important factor when discussing projectiles. It may only have the kinetic energy of a .22, but it has loads more momentum, making it many times more dangerous.
@@Archaic-Arms on the plus factor for bullets, the higher velocity and smaller diameter of the projectile gives the opportunity for more penetration. A man hit square in the chest with a sling could get their sternum broken and survive, but a person shot in the chest from a .22 might get their heart or lung pierced and die from that.
@@Archaic-Arms While people compare the slung rock projectile to a bullet energy, saying it doesn't come up to similar energy, what people don't equate is the comparison of momentum. A big heavy rock slung at moderate speeds has a LOT of momentum and wont stop easily. The damage is blunt force, unless of course you choose the impact "point" carefully, such as a slender oval rock flung like a football. Just to pick a random middle value from the published list: 18" sling: 313g 32m/s = 160J , 10.0kgms Making the conversion-------------- 4,830 grain projectile, 105 FPS, 118 ft-lb energy. Momentum is 72.5 ft-lb/sec!! That's exactly equivalent momentum (not energy) to a 230gr slug shot from a .45acp at 2,206 FPS!! This of course is due to the fact the stone weighs 21 times heavier than the mentioned bullet. Energy gets all the attention in the firearms world. People may not even understand how to equate momentum, or what it is. Math calculating for energy rises quickly with velocity. Math calculating for momentum rises quickly with mass.
If your numbers are accurate (and I'm not doubting them) you are hitting harder than a modern high end crossbow, which would absolutely wreck medieval plate.
It certainly would be an interesting experiment! A big stone cant penetrate like an arrow, but has lots more momentum even if they have the same amount of kinetic energy. A square-on helmet shot would be lights out, that's for sure.
My North-American-trained noggin had to work out some values to understand what sort of speeds we are looking at here, but yeah - I am going to say that a rock traveling upward of 135 miles per hour is going to be able to get some work done!!! Great stuff here, thanks for sharing your skills with us all.
You can use the same ammo for most length slings, but short slings are more comfortable to use with heavy stones. Lighter projectiles are generally used with long slings, because they go the fastest and furthest. However, heavier ammo will always give higher kinetic energy, no matter the sling length.
_And it came to pass, when the Philistine arose, and came and drew nigh to meet David, that David hasted, and ran toward the army to meet the Philistine. And David put his hand in his bag, and took thence a stone, and slang it, and smote the Philistine in his forehead, that the stone sunk into his forehead; and he fell upon his face to the earth._ 1 Samuel 17:48-49 KJV With the correct shape and weight, and enough velocity, pretty effective.
I will make a tutorial soon. It's not just practice but also how you practice. Practicing each specific element individually and being aware of their effects, helps to learn faster. It also helps to watch skilled slingers when learning technique.
No disrespect to you. You are a great slinger , but is your crony working correctly? Those numbers seem really high. Alot of good slingers range in the 30m to 40m/s range. Is it possible that your crony is reading the end of the sling cord whipping past?
Just FYI(and I realize this is an old comment), I've tested this by dry-firing the sling in front of, next to, behind the chronograph, and it just doesn't pick up the sling cords. It is definitely reading the slung projectile's velocity. I also verified the values from the chronograph with a bright projectile, measured distances with stakes in the ground, and high-speed video.
I have to know what that device is ur using to get the readings!? I have been using a regular chrono and it takes literal hours to get good reads, and I've hit mine once in a month. What is that thing and where might I get one? Thanks!

@@Archaic-Arms on the plus factor for bullets, the higher velocity and smaller diameter of the projectile gives the opportunity for more penetration. A man hit square in the chest with a sling could get their sternum broken and survive, but a person shot in the chest from a .22 might get their heart or lung pierced and die from that.
@@Archaic-Arms While people compare the slung rock projectile to a bullet energy, saying it doesn't come up to similar energy, what people don't equate is the comparison of momentum. A big heavy rock slung at moderate speeds has a LOT of momentum and wont stop easily. The damage is blunt force, unless of course you choose the impact "point" carefully, such as a slender oval rock flung like a football.
Just to pick a random middle value from the published list:
18" sling:
313g 32m/s = 160J , 10.0kgms
Making the conversion--------------
4,830 grain projectile, 105 FPS, 118 ft-lb energy.
Momentum is 72.5 ft-lb/sec!! That's exactly equivalent momentum (not energy) to a 230gr slug shot from a .45acp at 2,206 FPS!! This of course is due to the fact the stone weighs 21 times heavier than the mentioned bullet.
Energy gets all the attention in the firearms world. People may not even understand how to equate momentum, or what it is.
Math calculating for energy rises quickly with velocity.
Math calculating for momentum rises quickly with mass.
amazing!
Thank you for the summary!
If your numbers are accurate (and I'm not doubting them) you are hitting harder than a modern high end crossbow, which would absolutely wreck medieval plate.
It certainly would be an interesting experiment! A big stone cant penetrate like an arrow, but has lots more momentum even if they have the same amount of kinetic energy. A square-on helmet shot would be lights out, that's for sure.
My North-American-trained noggin had to work out some values to understand what sort of speeds we are looking at here, but yeah - I am going to say that a rock traveling upward of 135 miles per hour is going to be able to get some work done!!!
Great stuff here, thanks for sharing your skills with us all.

close call for the bird
He better be careful he doesnt hit that boast 😅😂😂😂
A video of you doing this into the side of a car and then cut down in to shorts would blow your channel up
Get a van and paint subscribe on the side.
So lighter projectiles for longer sling heavy projectiles for shorter?
You can use the same ammo for most length slings, but short slings are more comfortable to use with heavy stones.
Lighter projectiles are generally used with long slings, because they go the fastest and furthest.
However, heavier ammo will always give higher kinetic energy, no matter the sling length.

Fastest one at 77m/s
That’s 172mph! Imagine a 42g sharp chunk of lead coming at you at 172mph…
how much damage would these do to the human body?
_And it came to pass, when the Philistine arose, and came and drew nigh to meet David, that David hasted, and ran toward the army to meet the Philistine. And David put his hand in his bag, and took thence a stone, and slang it, and smote the Philistine in his forehead, that the stone sunk into his forehead; and he fell upon his face to the earth._ 1 Samuel 17:48-49 KJV
With the correct shape and weight, and enough velocity, pretty effective.
Could you make a tutorial on how to make this ? Also, much practice is required to get decently good at this? Thanks
I will make a tutorial soon.
It's not just practice but also how you practice. Practicing each specific element individually and being aware of their effects, helps to learn faster.
It also helps to watch skilled slingers when learning technique.
@@Archaic-Arms thanks! Will be waiting
What device did you use for measuring projectile velocity?
FX pocket radar
@@Archaic-Arms Thank you!
No disrespect to you. You are a great slinger , but is your crony working correctly? Those numbers seem really high. Alot of good slingers range in the 30m to 40m/s range. Is it possible that your crony is reading the end of the sling cord whipping past?
Just FYI(and I realize this is an old comment), I've tested this by dry-firing the sling in front of, next to, behind the chronograph, and it just doesn't pick up the sling cords. It is definitely reading the slung projectile's velocity. I also verified the values from the chronograph with a bright projectile, measured distances with stakes in the ground, and high-speed video.
What is the chance that your detector is recording the back-swing... in other words, the pass just before the release?
Did your arm hurt after that? I recently did a long session and 2 days later it still hurts
I have to know what that device is ur using to get the readings!? I have been using a regular chrono and it takes literal hours to get good reads, and I've hit mine once in a month. What is that thing and where might I get one? Thanks!
I'm using the FX pocket radar chronograph. (Thanks to Iron Goober for finding it)
Any idea about the range?
.22lr 탄환이 약 150J 되지 않나요?
