For one I don't care the WoT ads, and I don't need an explanation of how this works and 5 minutes of loading the gun. Just came in for what the title says. Not everyone is dumb as shit.
You were shooting the rounds technically at spaced armour. I wonder how many it would go through if they were put one after another with no space in between.
i think maybe 10...these rounds have so much power, even when the round shattered into pieces it penetrated the steel plate behind In different sources i have read, that the rounds penetrated 30mm steel at 100m (almost 1,2 inches).
@SwiftMooseBlz Maybe newer armor but i promise you that the armor that the ladi would be firing at had no air gaps assuming ww2 germany. the rolled homogeneous steel that germany used had no gaps. russia with as slaped together as their tanks were once again the armor was solid steel. modern day armor on things like a cheiftain yes but im sure its in a honeycomb formation. dont quote me on that the tech that the britts are using is "top secret". and the Americans use ceramic in their armor. im not sure in what fashion all i know is they do.
When you space out the metal sheets, its created a tougher shield then if they were all held together. spacing is actualy used in tanks sometimes for extra protection.
it's nothing like 4 inches of homogeneous steel plate. spaced plate will stop more than equivalent thickness of single plate. also flexible mounting increases the level of protection. 6 plates being an inch and a half I know damn well it would penetrate over 2 inches equivalent steel.
Agreed, the plate spacing essentially created a Whipple shield. One of the most efficient armor types in regards to weight of system vs. stopping power. Fun fact, Used by NASA to stop micro meteorites/objects traveling much faster than bullets. That being said 6 plate penetration is an amazing accomplishment.
Spaced and flex plates absorb more energy than an equivalent thickness of solid plate. The Lahti could penetrate 30mm of steel, equivalent to 6 1/4 inch plates.
You are right about the flexible mounting. If all 4 edges of the plates were encased in wood, they would have been more rigid. The way they were in the video, they acted as a shock absorber.
Instead of showing us building the Plate holder and counting plates 67 times they coulda 1. Showed the cottage of the misfire 2. Shot the training ammo he mentioned not wanting to use because it’s just steel instead of tungsten. 3. Compare training VS AP penetration. 4. Shot another caliber like 50BMG or .338 (win mag, lapua mag, Norma mag whatever) or just 30-06/308 to compare the difference in penetration capabilities… ECT.
Arosankari What do you mean "does not try enough"? War Thunder tries to make it realistic by going off the tanks real stats. And they make you play smart by learning each tanks weakness to be able to successfully take them out. World of Tanks is honestly too arcade like for me, some tanks reload in 3 secs and their is a stupid health bar. But hey that's my opinion, you do you.
Actually, the spacing would increase the effective thickness of the material against a ballistic penetration by a small ammount. This is why spaced armour was used by early cold war tanks.
Keita Marislo It still will, side skirts are very thin as they are supposed to break or detonate shells before they reach the armor. Anti-tank guns have been historically shit against spaced armor, and that is why there’s also so much spaced armor everywhere on the PZ 4 H.
Yes it could have been 2 minutes but he has to gain something from going out of his way to record all of this and make it, stop complaining its not like you pay to watch anyway
Improper test for an AP rifle. You put space between each plate which allows the round to expand and lose momentum. (note each hole gets progressively bigger) Do the test again with the plates welded together and you very well then punch twice as far. I can assure you with the kinetic energy in that round it will not ricochet. The manner they are used is to shoot within the trackwell (wheelwell) of a tank where the armor is thinnest to kill the driver so it can then be routed by Infantrymen with antitank weapons as it's then a sitting duck. Not to kill the tank itself.
Too be fair most tanks have either explosive or non explosive reactive armour. so this is a pretty decent test , a real armour would let even less pass threw.
I don't think it has much effect coz no energy is lost due to air. And holes get bigger coz the impulse get shorter and hence velocity and therefore the impact will get enough time to get shared to all neighborhood atoms.
Ethan Jordan Yes. All that work for one round? He has all that steel & really nice jig, why not throw as many different rounds as possible at it? Right? Nice camera tho.
Against modern .50 it would be about the same, it was only good against light armor. It worked against the original PZ II but any tanks after that it was fairly useless unless you could manage to shoot the treads and de-track it
+SilvaDreams They have almost the same muzzle velocity but the 20mm is far more heavy. A 20mm shot from this rifle would certainly be superior over a .50.
The service AP munition from the L-39 is about 3 times the energy of the 12.7x99 /.50 BMG. The bullet from the 50 BMG weighs between 600, and 700 grains, while that of the 20x138B weighs about 2,500 grs.
The gun along with the slow mo camera footage made an incredible vid. I would certainly love to see this same setup with modern ammunition because as you said, moisture would most certainly get in and affect ignition. Even with the round that you managed to fire, I absolutely guarantee that its performance was hindered due to all the years between production and now
Because a thing called adverfuckingtisment is part of business and it happens to be that RU-vid is a great place to advertise. Most people don't even watch anything on tv but the news now.
TechCheck: You're being sarcastic, aren't you? - what's funnier is that people take your comment seriously, at "face value" - "yeah, dude...AWWWWESOME!"
I was always wondering what is easier to penetrate: 10 thin steel plates set with small gaps, like in this video, or 1 thick plate of the equal thickness
Where do you Buy a 20mm Anti Tank Rifle and WHERE THE HELL DO YOU BUY THE BULLETS FOR IT....???. Last time I checked my Local Wallmart was fresh out of Anti-Tank Rounds and I filed a complaint for lack of Product. Thanks. Captain America.
With standard "black tip" .50 BMG AP ammunition, you're looking at about an inch of hardened steel (or four of those plates). With the spacing of the plates, it'd likely go through three and dent the fourth.
A lot of bullet energy was lost to metal plates flexing and dissipating the energy over the surface of every plate as the bullet passed through. I suspect it would have gone through a few more plates if they were bound together and non-moveable. The views from different angles and shutter speeds was pretty cool.
RAY RAY I meant that he should set up armor plates with different thicknesses and test the penetration. For example a sloped plate the thickness of the m4 sherman front armor. Etc
+White house gaming That would be epic. It's a shame, no one ever experiments with angled steel plates.. there are loads of videos with steel penetration tests but never at an angle!
pay to win ??? that is only for premium vehicles and the premiums are not the best in their BR and the missiles aren't guided you have to manually steer them to their target which is a difficult task. also the game is well balanced i dont see why you say it isn't because you wont see a Tu-4 while you are flying in a F4U corsair but yes along time ago the game was unbalanced.
WT is "realistic" game. Thats true. You can be oneshoted by anybody and do the same to the other players, but when you meet a BOT tank, its nearly impossible to kill him because Gayjin said FU. And the game balance? Bitch, please, its even more russian bias than WOT.
I am working on a video of a Red Rider BB gun shooting through 1000 evenly spaced sheets of aluminum foil. After that, I plan on a video of shooting through 1000 evenly placed sheets of saran wrap. I am sure these videos will be as useful as this one, if any military vehicle is ever made like this. A 50 BMG and see how many prius's it will go through would be way funnier.
ok... ur experiment is improper... ur shooting at spaced armor not armor thickness, ur experiment should be armor thickness, spaced armor is better at stopping rounds
and u arnt wearing proper PPE (personally protective equipment) how is this channel up if ur experiment is so inaccurate and ur so dangerous while doing so... just mind blown
TAKTİKSEL BİLGİ depends on the tanks armor not all tanks have ceremic composite armor. some light tanks have rolled homogeneous armor and steel plates as there main protection. :')
A trend I always see with RU-vidrs is having the plates spaced apart. This causes the shell to react as if it were penetrating spaced armor. This causes problems for Ballistic Capped shells as after its first penetration the fuse is set off, making it explode before hitting the next plate, which doesn't show its full potential.
I was messing around on Discord as I watched, and I started playing "(Dont Fear) The Reaper" as he shot the plates, and it honestly fits so well lmao Also I feel like you shouldn't have used spaced armor :/
That gun looks like it has alot of mass, and the more mass of an object, the more kinetic energy required to induce motion. Between the size, the gas system, recoil springs and the muzzle break I bet that weapon has less recoil than a standard hunting rifle.
There is more to this video. This video captured the recoil of the weapon. Watch how the energy from the recoil travels down the gun into his shoulder and then watch how that energy transferred down his spine into his hips on back. The physic of the projectile from the trigger forward is expected and was amazing. Still I find the physics from the trigger back almost as fascinating. It was amazing how far the shooters body traveled. Amazing watching the energy traveling from the gun butt into his shoulder. The last hole on sheet 7 is cool as heck for me. What a good video.
We used to fire 20mm out of twin Hispano Suizas mounted in the Avro Shackleton. Mostly we fired ball (black) rounds but occasionally we fired HE (yellow) rounds. We loaded 600 per side, and wound up the Belt Feed Mechanisms (BFM) with a torque wrench before fitting the BFM and connecting the ammo belt to the pre-tensioned belt. They had quite a high stoppage rate due to the crossover feed systems, and they were controlled by a gunner and joystick for up/down only, and the pilot corrected for windage and yaw. Needless to say they needed big targets like ships to hit! The worst thing was clearing jammed rounds because the gunner pointed the muzzles down at you while you stood in front and rammed a cleaning rod up the barrel!
When you separate the sheets like that the perforation will be less effective, because every sheet it trespass deforms a little bit the bullet and if you consider the friction of every perforation causing the bullet to bend or incline a little bit increasing the contact area. You can see the last holes more large than the first ones. In this case it would be effective to use an special kind of bullet instead, in order to keep the perforation the effective possible. It could be titanium tip, or put the sheets all together and I think it will pierce more than separating it.
TheBackyardScientist to be frank, no. even WWII tanks had enough armor to stop these shells, late war tanks had an effective armor thickness hitting 300+ mm. modern tanks have armor made out of multiple layers of super hard ceramics which would easily break up then absorb the shell. also, if you are the real backyard scientist, i love your stuff
Keth Wintham thanks for the info, I guess you could score a lucky shot and maybe disable (not destroy) the tank or at least some of it's instruments. And when you say effective armor of 300 mm, do you mean tanks actually ride around with that much armor plating or it would be the equivalent of 300 mm of steel? I'm just thinking that would be so heavy. I know tanks use a sort of stand off armor plating that makes shaped charge is much less effective, and I guess it would function like a whipple shield for any small caliber round.
TheBackyardScientist you would need a proper source to inform you on all of this, but i will give you as much as i can here. no, they would not carry that much armor, but there are ways to make it act that thick without being that thick. one of the primary ways is through the sloping/angling of armor. when a plate is sloped, the projectile hitting it has several problems. one is that the armor now has a face that isnt perfectly perpendicular to the point of the projectile, increasing the initial surface area it has to break through, and also increases the chance that the point wont create the small dent in the steel needed to guide it in, making it likely to glance off or start spinning end over end (which makes for pretty poor armor penetration). another problem it makes for the projectile is that even though the armor may only be 100 mm thick, the projectile has to go through more than that, because it is traveling partially upward through the plate. but some tanks do carry actual meter thick or greater armor. a modern m1a2 abrams is around 70 tons combat loaded, and uses a jet style turbine engine to compensate. the problem came when HEAT shells were invented, because they could punch through thousands of mm effective steel armor. this was essentially the cause for the invention of advanced composite armor, which is used on essentially every modern tank. i dont think this gun could do any serious damage to a modern tank, except in very specific and incredibly rare circumstances. abrams cost upwards of a few million bucks a piece, if something this cheap could disable them, they wouldn't be used. i highly suggest you search youtube for some videos which explain it better than i can here on my phone (where it is very hard to collect my ideas, then present them well, including everything with no redundancy.) this description is far from perfect, and is missing some pretty major things.
Keth Wintham thanks Keth, that's a great primer for me to start looking stuff up to learn more! I've read about the turbine engine in the Abrams tank before, it's an outstanding piece of technology , and it was designed to run on virtually any fuel. This kind of stuff fascinates me, and in an alternate life I would probably be working for the military developing weapons at china lake ;)
TheBackyardScientist definitely. im still young enough to pursue a career in chemical engineering (for explosives.) or military robotics, and would totally love to do that. i have had some interesting ideas about caseless ammunition and how to re-create greek fire, and have a bit of an addiction to it myself. if only i had the money, materials, and space to experiment with these things. :'( XD
Actually, this is how you set steel plates when you want to minimize the penetration of the bullet. The arrangement has been in use with WW II tanks, they had steel plate skirts around the tank, separated from the surface. Next time, try with a solid block of steel!
Spaced armor works best when the projectile's penetration ability is compromised by the first few plates so that, as in the test here, the ability to penetrate the later plates is degraded. This can be due to projectile damage, as here, spreading the area of impact wider and wider in each successive plate, or by deflecting the projectile on an oblique impact (using non-parallel plates perhaps) so that it hits the later plates at a higher angle, also increasing the hole size (more oval), or, also more effective at an oblique impact, causing the projectile to yaw or tumble due to inadequate spin stabilization, again making a bigger hole in the later plates. If none of that occurs, then parallel-plate spaced armor, as here, is usually significantly inferior to a solid plate of the same total thickness made up of the same steel and hardness hit at the same angle. Even laminated armor, where the thin plates are tightly pressed together by bolts or welding, would be better, though not by as much of an edge. We are talking about steel armor and pointed or oval-nosed AP projectiles that do not suffer complete shatter on an early plate's face (this is an extreme case of the progressive damage case). Against ceramic or multi=material composites (modern tank armor), things get much more complicated.
my deceased friend Bob Ardle bought a 55 caliber Lahti anti-tank gun and had it re-barreled for 50 caliber. It took the same magazine, and we shot it repeatedly. It was awesome!
By loading it in to the magazine instead of the chamber, it reduces the velocity of the bolt by virtue of the fact that it has to strip a cartridge out of the magazine. Without that added resistence, the bolt travels faster than intended, which can either damage the bolt, or at worst can make the firing pin jump forward and unintentionally fire the round.
i have a question. lets say If that bullet penetrates 6 plates But what if you stick together those 6 plates? my question is will the bullet could penetrate the sticked 6 plates? and if yes would have more power to go for the 7th?
I think then it will penetrate more of them. WWI shield was build on that principle with gaps between 2 pieces which helped more than 1 solid. But sure a test would be great.
Now I want to see it against a 1 1/2" plate , a 1 3/4" plate, and a 2" plate. It would be interesting to see if the gapping between the plates has an effect.
I feel it would penetrate more than that if it's were not spaced armor. Interestingly though the shot wasn't deflected. Starts off with a clean penetration and gradually switches to blasting through armor using sheer energy and making a bigger and bigger hole. The last sheet of metal that got penetrated must have been the one to absorb most of the energy since the round had lost it's penetrating shape and just punched through with kinetic energy leaving a huge hole. Pretty cool to watch and interesting.
Jesus Christ, that is just unreal! The muzzle blast from the weapon, the fact that it ripped clean through 6 steel plates-my God, that thing is not playin’ around!

Next time, send the other ammo type at whatever your shooting as well if possible. Who knows? If the ammo is fresher or has a lighter bullet, it might achieve higher velocities and penetrate better than you would expect. Either way you get crank off another round on camera! Love the slowmo!
+ultraboy222 I didn't say it would out perform the tungsten, just that it might do better than he would have expected. Especially if the powder was affected in the aged round he sent. Beside, who doesn't want to see a 20mm traditional bullet blow apart in super slow motion? That's a massive energy dump!
there are ABSOLUTELY 20mm DU rounds. I don't think you can buy them as a civilian, but they sure do exist. Kill bugs real dead. DU munitions are where "gulf war sickness" came from, from people inspecting shot out tanks that are full of DU dust. The advantage of DU and Tungsten is less in density, and more in sheer hardness. DU has an extra advantage because it's pyrophoric and self sharpening. It will spontaneously combust at firing speeds and as it pierces armor will always break in such a way that the tip is still sharp.
I always heard that air spaces are game changers. That, a round that might go through 3 inches will be stopped by three 1-inch plates separated by spaces
