Massive thanks to Guy Warnett (aka "the stuntman") and Carson Pollard for helping out in this one, and to all my supporters on patreon for making it possible.
@@gscapinelli9214 yes you can do, although it's going to be a pain doing it, because it's shear thinning, so it won't flow in the crevices on his own, and needs to be brushed in them.
@@Backyard.Ballistics Thanks! I had my doubts if it could somehow creep inside and contaminate the powder/primer. Btw, amazing channel. Love it. Cheers from Brazil.
@@Backyard.Ballistics u should try this again but next time use some of the new super hydrophobic coatings on the bullets that's made from fungus. I've seen videos here made with it on ball bearings. And they drop the bearings in water. One with and one without the coatings. And the one with the coatings goes thru water with near zero drag and full speed. The coatings cause cavitation on nearly everything and no drag. Would make angreat experiment 😎
@@hughgrection3052 coating would shear off travelling down the barrel and accelerating, might survive a bit on the front so it'd still possibly work but it'd be better suited to a spear gun i think
It's very similar to a villa/hotel i was stationed in while in toscana. The pool is similar, and so is the view, and more importantly, the villa is a repurposed police building.
@4:25 - When I lived in Hawaii, my dad was a sport diver. They regularly carried something he called a "bang stick" for contact firing against predators.
It's basically a stick with a 12 gauge shell loaded in the end of it. You pretty much have to press it against anything you're trying to dissuade/kill. Edit: Apparently they come in other calibers as well.
The USSOCOM Supercavitaing projectiles have been a wonderful discovery for me. I've always seen how bullets were pretty much rendered useless by water and sand due to certain physical phenomena, and to see how those bullets passed several feet of water and they were able to penetrate armour after that, and the same thing with sand surprised me in an incredible way.
when you talked about the gun having to be fully submerged, I recalled an anecdote I have been told: decades ago (probably 50s-70s) in my village, a huntsman wanted to shoot a pike in a stream while submerging the muzzle of his rifle. pulling the trigger was the last thing he ever did.
I love this part of your description --- "with your help, I can keep making educational content without having to give up my freedom of speech to the advertiser's needs."
Yes well that's why I was the one filming it instead of shooting it😂 Guy said he could feel the shock travelling through his body. In any case we decided to heep his ears out of the water, even though he was wearing earplugs
Very cool! I’d love to see a revolver underwater too. Also, maybe a longer barrel could be added to the power head if you ported it so water can escape out of the way - similar to a door breaching muzzle break or standoff.
Some of this myth probably comes from the existence of "maritime spring cups" for Glock handguns. They aren't meant to let the gun fire underwater, but to allow water to drain from the striker channel after the gun has been submerged. The other part is movies, especially "US Marshalls", which has dialogue specifically invoking the myth.
That, and a generally poor understanding of how propellants work. It's easy to wrongfully conclude that a firearm needs air, as they obviously work by making fire inside the chamber and barrel - which is why you'll also find people claiming that firearms would not work in space (a vacuum).
Normal people going for vacation: Yay a pool, lets jump in! Carlo and Guy going for vacation: You did bring guns, didnt you?! This video was excellent, as always!
I liked your stuntman. He seems like he's got a great sense of humor. 😊 I also kind of got a kick out of the inflatable shark floating around in the background. Hinted at the main use for the bang stick (which is what I've heard them called here in the US) without actually having to explain it. Wonderful video. Educational and entertaining. Of course I'd expect nothing less from your content.😎 Thank you for sharing this with us. Stay safe out there sir. 😎
Its a good clarification that the acceleration of a projectile decreases exponentially over barrel length, meaning that the first inch of barrel is far more "effective" then the last inch ;)
I have a question/recommendation about the the contact gun, what if the end of the barrel was able to be fitted with a solid rubber disk (similarly to certain spec ops suppressors that have a solid washer fitted after the last baffle instead of a hollow one, in order to allow the operator to go under water without filling the suppressor and gun with water before the first shot) this way you could have a longer barrel withput having to worry about the water, and the projectile would simply puncture this disk after firing (or the pressure buildup caused by the projectile compressing the air infront of it, not which would happen first). Would this be a viable way to get a longer barrel?
What if you used a full length barrel shotgun and sealed the end of the barrel? I suppose the difficulty there would be sealing the back of the action as well. Obviously, firing it once would break the seal, but theoretically, it would have the same effect as the shell with the air gap in the front. However, I wonder if the projectile would push the air in front of it forward with enough force to break the seal prematurely.
Re: your “improved round” using the brennecke (sp?) slug… with the slug at the front of the round, what’s the difference? Wouldn’t it still have zero momentum at point of contact, vs being accelerated before contact? BTW: I have been told that the point of the bangstick/sharkstick is that the projectile pierces the skin, then the gas expanding within the body does the damage. Is this not correct?
You might actually be on to a marketable loading, divers have been using these for decades, so a load that displays increased underwater performance might be worth something. Bit of a niche market, but you never know.
Fantastic content! sadly, UA-cam keeps burying your content even though I am subscribed. it apparently doesn't even show it on my "subscriptions" page.
i just thought of something and i thought it might make for a decent video, what happens if you get shot by a tracer round, does it burn inside the body like an incendiary round would.
Nice backyard, nice landscape and nice friends who let you shoot in their swimming pool. And nice video, of course. Question: what about bullets shot from outside the water? How far do they travel after they've hit the surface?
How does 45 ACP compare to 9x19 underwater? It's bigger but it's traveling a fair bit slower and is much heavier. I imagine it would going a fair bit farther. Relatively speaking that is
two things I would wonder about. first what about a short barrel only 2 or 3 inches that is ported so that the water can be displaced? secondly I wonder if a black powder load would shoot more effectively due to its rather instant ignition and burn rate not being affected by pressure like smokeless.
I imagine you could market long sealed loads like the one you made that would only chamber in a custom chambered "bang stick". A 4 or 5 inch water tight 12 gauge shell would get serious penetration.
I'm surprised you didn't mention the soviets underwater AK that shot a weird AG round, forgot the name, bit the bullet was probably around 6 inches long.
I had a "Bang Stick" when I was diving in shark-infested waters. They did not work as well as the "Shark Dart," an 8mm very sharp hollow tube. When contact was made a CO2 cartridge would expel its entire load into the shark, wrecking organs and making it buoyant. This also produced a lot less blood, keeping other sharks away.
I guess with a powerhead/bang stick firing a conventional round the primary wounding mechanism is likely to be the muzzle blast entering the body? Your shell seems like it might be quite marketable to people who use such devices.
I he held it the wrong way he colud have been injured, although the recoil velocity ia very low. Normally divers attach a proper handel at the end of the stick to manage recoil better, but I couldn't find any...
@@HeadhuntexGamer not nearly as bad as brits usually. We tend to get sunburnt as well, but while it happens to them in the moment they close their door for us it takes until we remove the key from the lock.
@@HeadhuntexGamer that is part of it. The other is that generaly people from these countries spent way less time in the Sun. I have lived in multiple really warm countries and hardly anyone there decides to just lay in the birght sun for an afternoon in the way most german tourists do.
I feel that the shell with the pole could have been done differently since I feel there was a risk to the stuntman getting impaled. Like a longer rod to extend past him or something similar to the butt of a rifle. Interesting watch though!
Chlorinated water is particularly aggressive towards steel, especially stainless grades 304 and 316, which contain Nickel in the range between 8 and 12%, which is the most susceptible of stress corrosion cracking, a very fast and dangerous form of localized metal corrosion. Its residues once the water evaporates, on the other hand, are much less damaging than those of saltwater. In any case the gun was thoroughly rinsed, dried and oiled afterwards
Beautiful landscape. Anyway I suddenly thought of that guy who fires his khar pistol into a bucket of water in his bathtub. It blew up in his hand, no injuries.
The powerheads used in Australia have a .303 bullet (165 gn). They will kill a shark. (Presumably due to the rapidly expanding gases and hydrostatic shock effects).
