The .223 and 5.56 difference wasn’t so much due to chamber pressure but the fact that the M193 (.223) has a lead core while the M855 (5.56) includes a steel penetrator. That is likely why you saw more sparks in the 5.56 and a deeper dent.
@@potroast1797 what's your point? He is pointing out that the two loads utilize different bullets, which obviously has more to do with the different results than any of the other differences between .223 and 5.56mm.

@@ArKritz84 haha EXACTLY. You guys see vid of the Russian soldier recently who took a ricocheted 30 mm round to the chest and survived?!? Pulled this thing out whole from his steel plate on his chest. Wild
You need to collaborate with Scott from Kentucky Ballistics and get some high-speed footage of his 4 bore rifle vs. ballistics dummies! It would be super interesting to see the dummies vaporize with your super high-speed camera.
Ive seen a lot of high speed like this but that 50 cal was just shocking. That jacket spinning off to the right might as well have been a throwing star fired from a fire arm. Great job guys!
It's kind of funny because they seemed to either over estimate the plate, or not really know what .50 BMG is lol. The fact they thought the plate would stop kind of shocked me
Kind of a big jump from 308 to 50bmg. Would like to see some intervening steps like: 6.5 Creedmore, 300 win mag, 338 Lapua, and 416 Barrett. THEN try the 50 but start with FMJ and go to Black Tip AP. Great vid, as always!
I've watched a lot of slowmo gun/bullet stuff but the way you film it and how you have everything set up really allows you to get the most out of every shot. I remember watching other videos on other channels thinking "that slowmo footage sucked", but everything is so good here. Love it!
I have been shooting 50 BMG SINCE 1988. Have reloaded in excess of 4000rds. The M 33 ball round has a mild steel core not lead. I believe that it what penetrated the plate. Love this channel. Keep up the great interesting videos. Thank you! Been shooting 1000 yds several times. Using a Serbu BFG50 and Windrunner M 96
Amazing job and so cool! You can see the steel core of the .50 cal slow down when it hits the plate as the copper jacket maintains its speed into the plate.
These videos will never get old to a gun nerd like me … I have some HEI 7.62x54r rounds that would be cool to see what they look like really slowed down
Looking at this I'm just simply amazed by the tech we have at hand. To be able to see and hear a freaking .50 BMG travel through air and deal that much damage at 250k FPS is simply glorious. Nice job guys.
I agree, the tech really is amazing, but just to let you know, this type of high speed doesnt have sound, so the person editing the video will usually add sound clips afterwards that match the recording (which I find equally amazing). Here is a video from the Slow Mo Guys where it's explained well, hope this helps! ruclips.net/video/EHD5PRrS4Ns/видео.html

High speed cameras can't record sound simply because sound is just too "slow" to even make it into a single "frame". The sound we hear is masterfully edited to match what we see, but it's not the actual sound
One thing to note is m855 green tip has a steel core for (penetration) which is probably why the 5.56 did more damage to the plate. Great channel keep it up!
@@Fadaar uh nope. Black tip is armor piercing, also is called m995. M855 is a steel core, medium shade green painted tip (or no color at all for some foreign users). M855a1 is a tungsten core has a half copper jacket with more OD green tip.
And the 50 cal projectile has an all-steel core. Of course it blew through the plate like it was nothing at all. The jacket was stripped and the steel core barely noticed the plate.
Should note the 300 blackout was moving at subsonic speed. 300 blackout comes in many different loadings, both subsonic and supersonic. Also wish you would state the weight of the bullet. Since energy is mass x velocity squared, that would be interesting to know.
A. The .50 folded the rounded plate concave! B. Now we can see the optimum "expansion chamber" distance before the first baffle on the expansion cone coming out of the front of the end of the barrel....the first baffle in a suppressor should start just beyond that point in order to allow the best expansion of the gasses leaving the barrel before it starts capturing it and rolling it back...most appear to be like 5-7" from the end of the muzzle device Very cool!
As someone else commented, it would be awesome to see large clay blocks shot in ultra slo-mo! Additionally, if you can get your hands on them, seeing .50BMG black tip, blue tip, and the red/silver tip fired at a steel plate in ultra slo-mo would be incredible!
Ricochets would be an interesting video down the line, now that we've looked at fragmentation. Another idea that springs to mind is bullets spinning on ice but that might be a bit tricky to capture, anyway love the content. I've been looking forward to this one, this channel is gonna blow up in popularity.
Not sure if it was mentioned in the comments but the effect you are seeing at 07:22 - is called the Schlieren effect. When you have a point light source, in this case the sun, illuminating the subject, the shock wave that the bullet creates is visible in the shadow due to the refraction of the light from the source. The refraction , due to the compression of the air by the shock wave, causes the light to bend and scatter. The presence of a shock wave is not indicative to being super-sonic.
I like the current format. Rather than the focus being on the target. The focus is on what happens to the projectile. It's the first time I've seen fragmentation in so much detail.
14:34 The muzzle energy was 17.265kJ or 4128 thermal calories. Food calories are actually 1000 thermal calories, so a .50 cal BMG = 4 calories. A single McDonald's french fry contains around this amount.
I havent finished the video but I would be interested to see a muzzle loader ball. the cavitation on the gel from the 7.62x54R was cool, the .50BMG was insane.
Awesome video, as usually. The visuals are just spectacular and the quality is so good. One issue: it seemed like the data for energy and velocity for the 7.62 x 54 was the data for the 7.62 x 39. They were identical. I was expecting the Mosin round to have a lot more energy. I might be mistaken. Looking forward to the next one.
I don't think this was entirely fair to the 54R, it was shot out of a carbine barrel. You can lose a couple hundred FPS with that much shorter of a barrel. My full length M91/30 (28.7" barrel) will launch a 150gr bullet at upwards of 2,800FPS, or 2,690 ft/lbs of energy. I do also think their muzzle energy number was copied from the x39 on accident; 54R should absolutely have significantly more than 1500 ft/lbs of muzzle energy either way.
I was thinking the same thing. The 7.62x54 should be moving approximately 350-450 FPS faster than the '39. Of course it could have been an intentional "comment generator" too. Either way no '39 is duplicating '54R velocities.
I was pretty sure the 50 BMG was going to puncture. You guys need to see if you can find (or similar): .444 Marlin or .45-70 Govt, 7mm Rem Mag or .300 Win Mag, .375 H&H Mag, any of the .416s, &or any cartridge that ends with "Nitro Express"
I would like to see the same video on mild steel. You would have to be extremely careful to protect yourselves from ricochet, but almost every rifle round (other than .300blk) would leave awesome gouges in the steel like it’s butter. We could also learn more about how ricochet happens when shooting steel.
Great video! Would have loved to see something like a 40 grain 22-250, something small, but super fast, pushing 4k fps. I've put dings in AR500 steel at 50-75 yards with mine. Keep up the great work!
Thewoundchannel did a video shooting level 3 plates with 22-250 and a couple rounds punched straight through cause of the ridiculous velocity it can produce
Cool video, and filming! It's refreshing to see something like this without all the bad jokes and stupid attempts at humor that many of the other slo-mo and gun channel people do!
The kinetic energy transferred into the plate from the 50bmg was immense!! You could see the plate distorting as it vibrated .. To make a plate that thick with a relatively small area in relation to it vibrate like that takes a HUGE amount of energy.
That .50 was awesome, it looks like it punched and shattered the plate rather than penetrating with a nice hole. It would be neat to see a slowmo of the back side of the plate when that hits to see what the bullet looks like on the other side. I'd also love to see some different types of rounds, like armor piercing, tracer and incendiary. I think those would give some very interesting results when they impact.
The black dust isn't a burning sticker, it's just dust. Lead dust, to be more specific. That's why indoor ranges need proper ventilation and air filtration. The sparks come from the tiny amounts of steel that were abraded off the surface and heated to ignition temperature as a result.
I was thinking that too. At one point I was shooting air rifles into a 22 rimfire trap in the basement, and I noted I was getting the occasional spark when the pellet hit. My "big" rifle was a 22 that ran at something like 850 fps, so it was just scraping the paint off instead of abrading the steel. When I realized that the lead dust from the pellets was probably what was burning, I quit shooting air rifles in the basement.
It would be really interesting to see how anti spalling coating would effect things. Some people swear it does nothing but steel armor manufacturers say it works near flawlessly.
I mentioned it on the community post, but I'd love to see more data on the rotation and rpm. I've seen a lot of videos on impact, but almost none on rotational inertia and what it can do to a target, etc. Twist rates vs muzzle velocity and such. If you get time! I'm sure you guys are quite busy.
Great high speed video. It would probably help you guys out to know more about the cartridges you test, even rudimentary knowledge at that. When a guy says the bullet was "probably moving faster" when the velocities are typically printed on the box is revealing. Nothing in this was unexpected but still fun to watch. FYI the fifty has comparable speed to the 5.56. Speed and mass rule the day.
I absolutely love these videos. I'd love to see a wide array of shotgun rounds and maybe revisit the same calibers from past videos with different targets eventually. You guys are adding some great informative content to YT. Thank you for that.
Absolutely great video! I miss calibers like .338 Lapua, .300 Win Mag, .460 CheyTac and some other hunting calibers. Would be great to see another video with these :)
And a 22-250. I've dented plates with mine. My friend hit the exact same spot with his .556 and it went completely through. It's all about muzzle velocity and bullet type.
The difference between the 223 and the 5.56 in the armor is most likely due to the steel penetrator in the M855. The velocity difference between a 223 Remington 55gr FMJ-BT (I'm guess that's what you used) and a 62gr 5.56NATO load isn't that different if fired from the same barrel due to the higher pressure allowance on the NATO round.
Awesome video! Using the block to visualize the shrapnel was a great idea! Looks like the velocity and energy stats for the 7.62x39 were used for the 54R as well.
Not hard to figure out. Say you have a 1:12 twist barrel, or one revolution in 1 ft. So 3,000 ft/sec would also be 3,000 revolutions per sec, or 180,000 rev per minute! If it's a 1:6 twist, 3,000 ft/sec would be 6,000 revs per sec.
At approximately the 7:30 mark, that is called the "Schlieren Effect" & "Schlieren Imaging" takes advantage of that effect to study the supersonic shock wave(s) that is/are being formed on projectiles, rockets, missiles, supersonic aircraft, etc.
The filming and editing was absolutely superb. Math not so much. At least with the .50 you went a little crazy. 4067 m/s V0 would be some kind of railgun speed (abt. Mach 12)🤣🤣🤣. .50s do around 950 m/s max. Edit: Also your Indikation for m/s should always be smaller than ft/s😉.
Great video! I would have LOVED if you had included 6.5 Grendel and Creedmoor though! It would be interesting to see how it fragments relative to 556 and 762x39 Love your vids!
I agree. All of the 6.5's and higher with a .308 comparison or comparisons. I am looking to buy a powerful distance rifle with extreme destructive capabilities but with low cost rounds as compared to a .50 . Something with mileage capabilities that is affordable.
My hat's off! I bet you'll see a lot of spikes in the videos's audience retention chart 😉. Beautiful imagery there guys. You're setting the bars so high in the guntube. Keep up the awesome work. Thank you so much.
4:08 I built a target stand specifically for steel target shooting for my wife before she got home. She shot five rounds of .300 Blackout soft point handloads out of a bolt action Ruger Ranch. We noticed a pancake of lead on the ground, along with smaller discs of copper and lead. She thought it took chunks out of the 3/8th steel plate. I had to show her your high speed video. We also noticed the lead spray all along the sides, embedded into the 2x4 legs.
A true test of the effect of velocity would be hand loads in 300 blackout sub and sonic, 308 Win, 30/06, 300 Win Mag. All with the exact same bullet just at different speeds. That would really compare apples to apples. Lovin the shots that you get. Keep em coming
Great video as always! Other military sniper cartridges like .300 Win Mag and .338 Lapua would be interesting steps between the 7.62/.308 and the 50 BMG.
The reason the plate cracked so much is because it's a Hardox type steel. Very brittle. Use a piece of mild steel plate and you'll get a smooth hole go right through.
It makes sense, having heard .50 bmg ring on plate , but actually seeing that degree of oscillation in something so solid is amazing. But it was all amazing to watch ,thank you .
Cool visual effects! A true test of the 50bmg would have been to shoot it at a fresh spot 2 or 3 inches away from the other impact spots. I know it didn't look like the other rounds did much of anything, but after that many high velocity hits in such a small area, there was likely some significant metal fatigue in that area of the plate. I'm not saying that the 50 wouldn't have gone through, I just think it might have looked different impacting a slightly more resilient part of the plate. Great video!

The green tip 5.56 has a piece of steel at the tip, so it can put a dent in the metal when a .223 can't. There are rare cases where a green tip 5.56 can penetrate a steel sheet when a .223 rounds can't, but it's not usually, because of the velocity/power, it's because of the steel tip. It's not really "armor piercing" like many people believe, but it does help it penetrate soft armor better. It doesn't flatten and spread out the energy like a jacketed lead tip bullet will do with soft armor.
The amount of unburned powder and gasses that exit the barrel has always amazed me. It seems to be inversely proportional to muzzle velocity. If you watch the closeups of the 7.62x39 very closely there is also a second shock cone off of the base of the bullet. No surprise at all that the 50BMG penetrated the target. 15:00 "Some of this is going to be metal leaving. . ." Lead, copper and steel are ALL metals. Overall, very enjoyable!
I just wanted to take a moment to say how amazing your video was! I was really impressed with the quality of the footage, the editing, and the overall presentation. You did a great job of explaining the topic in a clear and concise way, and I learned a lot from watching your video. I also really appreciated the way you made the video engaging and entertaining. You kept my attention throughout the entire video, and I never felt bored or lost. I would definitely recommend your video to anyone who is interested in learning more about the video. Thanks again for making such a great video! I look forward to watching more of your content in the future. PS: I outsourced this feedback to AI.
250,000 feet per second is about 47 miles per second or 170,000 miles per hour. The bullet can reach the moon in 1 1/2 hours if fired from earth. That's even faster than a giant meteor racing towards earth from outer space.
I believe that they were stating Frames Per Second for the camera. Confusingly that information was given right after the Feet Per Second data. FPS and FPS descriptions can be a bit of a hiccup for viewers. At least Meters Per Second were given also to help reduce rewinding time and improve efficiency with comprehension. The photography was outstanding but the info included as captions needed some editing and clarification.
Suggestion: Go to the other end of the spectrum. Air rifles come in 3 flavors. 1. Pump-up pneumatic; 2. Pre-charged pneumatic: and, 3. Spring action. The first two have excellent accuracy without special procedures. The third, spring action (usually a “break-barrel”), is mechanically simple but the accuracy is dependent on the movement of the gun in response to the motion of its internal piston and to how the shooter holds the weapon. The recoil of the action and the resulting movement of the barrel BEFORE the projectile leaves the muzzle has never, to my knowledge, been analyzed. Filming a spring action air rifle at high speed can clear up the mysteries of recoil, barrel motion and shooter grip, all of which greatly affect accuracy. Thanks
There was and maybe still is a gentleman that called himself "B. B. Pelletier" who wrote for an air gun retailer's blog. He used what he called an "artillery hold" to shoot spring/air rifles. The basic premise was that a person could not hold a spring/air rifle perfectly still and an attempt to hold it hard would not be successful because of muscle fatigue. The core principal of the artillery hold is hold the rifle so it recoils the same way every time it is fired. That leads to consistent motion during the shot release and resulting gilt-edged accuracy. I would like to see some high-speed video of a spring/air rifle being fired. It would be interesting to see the differences between a hard hold and an artillery hold and if the difference could be seen in the rifle's motion while the piston was hurtling forward.
In the final shot, you can see the core of the round slow down and back out of the outer casing, as the outer casing breaks down, the bullet core then passes through at a much lower speed
Correction at 14:32: The velocity of the .50 BMG is about 910 m/s.
4 km/s would be sweet
I figured out that same thing. There is just a small mistake. actually it is something like a 914m/s.
@@chaprandom8362 Explosives does abaut that speed. Some ones are faster and some ones are abaut that speed. That would be sweet for a bullet.😅
@@chaprandom8362 It would even penetrate a tank with this amount of speed
To have that energy and speep the bullet would have to weigh about 2 grams
The .223 and 5.56 difference wasn’t so much due to chamber pressure but the fact that the M193 (.223) has a lead core while the M855 (5.56) includes a steel penetrator. That is likely why you saw more sparks in the 5.56 and a deeper dent.
yeah it's not only about size and velocity so many types of rounds
This is exactly what I was going to point out.
Anyone that reloads knows and understands that it’s not the round but the chamber between the two that is different
@@potroast1797 what's your point? He is pointing out that the two loads utilize different bullets, which obviously has more to do with the different results than any of the other differences between .223 and 5.56mm.

I find it incredible to see the whole plate vibrating after the 50bmg hit it. Excellent video.
That was so gnarly. Just the sheer energy!
What if a 125mm round hit it?

Clay looks awesome in slow motion, but ballistic soap does the same thing better.
Or Led block
Definitely Clay!!!
I like the current format. Rather than the focus being on the target. The focus is on what happens to the projectile.
It's the first time I've seen fragmentation in so much detail.
@@bigb018never heard of ballistic soap that sounds awesome
Man I've been waiting for such a format for years!!! =D
Great content guys! Love it
Will tannerite Stop a bullet in Slow motion:
Shoot a small cup of tannerite, and see if the bullet passes trough or gets stopped by the explosion.
will a bullet penetrate air? the answer is yes.
@@mervunit ever heared about explosive shielding on tanks ?
14:34 The muzzle energy was 17.265kJ or 4128 thermal calories. Food calories are actually 1000 thermal calories, so a .50 cal BMG = 4 calories. A single McDonald's french fry contains around this amount.
You guys forgot the most important stats of all: the plate steel itself. What kind of steel is it, how heavy is the plate, and how thick is it?
Yeah, kind of useless without that information.
I wish I had a rifle that did 250,000fps
They said it was AR500 steel plate it's 1/4" thick chest plate
I havent finished the video but I would be interested to see a muzzle loader ball.
the cavitation on the gel from the 7.62x54R was cool, the .50BMG was insane.
It'd be cool to see a "Rounds through History" kinda thing. .70 ball, minie, cowboy loads, etc.
Or a shotgun slug would be cool to
Awesome video, as usually. The visuals are just spectacular and the quality is so good.
One issue: it seemed like the data for energy and velocity for the 7.62 x 54 was the data for the 7.62 x 39. They were identical. I was expecting the Mosin round to have a lot more energy. I might be mistaken.
Looking forward to the next one.
That was likely a mistake; 7.62R is often compared to a 308 in kinetic energy
I don't think this was entirely fair to the 54R, it was shot out of a carbine barrel. You can lose a couple hundred FPS with that much shorter of a barrel. My full length M91/30 (28.7" barrel) will launch a 150gr bullet at upwards of 2,800FPS, or 2,690 ft/lbs of energy.
I do also think their muzzle energy number was copied from the x39 on accident; 54R should absolutely have significantly more than 1500 ft/lbs of muzzle energy either way.
I was thinking the same thing. The 7.62x54 should be moving approximately 350-450 FPS faster than the '39. Of course it could have been an intentional "comment generator" too. Either way no '39 is duplicating '54R velocities.
this is the only place that has videos i wish kept going longer instead of the opposite!
nice work
I was pretty sure the 50 BMG was going to puncture.
You guys need to see if you can find (or similar):
.444 Marlin or .45-70 Govt, 7mm Rem Mag or .300 Win Mag, .375 H&H Mag, any of the .416s, &or any cartridge that ends with "Nitro Express"
Awesome view of what really happens as bullets transfer their energy
I would like to see the same video on mild steel. You would have to be extremely careful to protect yourselves from ricochet, but almost every rifle round (other than .300blk) would leave awesome gouges in the steel like it’s butter. We could also learn more about how ricochet happens when shooting steel.
Great video! Would have loved to see something like a 40 grain 22-250, something small, but super fast, pushing 4k fps. I've put dings in AR500 steel at 50-75 yards with mine. Keep up the great work!
Or .220 Swift?😃
I've never shot ar500 plates but I have blown holes through steel with my 22,250
@@TheWasillamike or 204 Ruger it has one load that's even faster then the 220swift
Thewoundchannel did a video shooting level 3 plates with 22-250 and a couple rounds punched straight through cause of the ridiculous velocity it can produce
.220 with a 40grn will push just north of 4200fps.
22-250 is a nice one also. Have one of each and hand load.
Awesome video guys. I think seeing arrows with different broadheads hitting a steel plate would be something different and interesting.
Cool video, and filming! It's refreshing to see something like this without all the bad jokes and stupid attempts at humor that many of the other slo-mo and gun channel people do!
I really wish yall would have did a 22-250 or 220 swift... well over 4k fps with a 40g would have been really neat to see!
The kinetic energy transferred into the plate from the 50bmg was immense!! You could see the plate distorting as it vibrated .. To make a plate that thick with a relatively small area in relation to it vibrate like that takes a HUGE amount of energy.
Raufoss round??? That would be nice. 😁
That's well over $100 round.. but yes you are absolutely right that would be awesome
I second that idea as I said on a previous video
MK211 mod 0
☕🤔🇺🇸
@@Sniper--tf3qt I'd donate one :D
@@BuffRANGE one dollar is not quite enough to fund a raufoss, but its a piece of the way there 😉
That .50 was awesome, it looks like it punched and shattered the plate rather than penetrating with a nice hole. It would be neat to see a slowmo of the back side of the plate when that hits to see what the bullet looks like on the other side. I'd also love to see some different types of rounds, like armor piercing, tracer and incendiary. I think those would give some very interesting results when they impact.
They can setup a mirror to capture rounds breaking through the back side of the armor in high speed
The black dust isn't a burning sticker, it's just dust. Lead dust, to be more specific. That's why indoor ranges need proper ventilation and air filtration.
The sparks come from the tiny amounts of steel that were abraded off the surface and heated to ignition temperature as a result.
I was thinking that too.
At one point I was shooting air rifles into a 22 rimfire trap in the basement, and I noted I was getting the occasional spark when the pellet hit. My "big" rifle was a 22 that ran at something like 850 fps, so it was just scraping the paint off instead of abrading the steel. When I realized that the lead dust from the pellets was probably what was burning, I quit shooting air rifles in the basement.
It would be really interesting to see how anti spalling coating would effect things. Some people swear it does nothing but steel armor manufacturers say it works near flawlessly.
There are vids out there that show how incredibly well the Anti Spalding coating works.
The 50BMG Muzzle Velocity seems way off, 4000 M/S is definitely not right
That footage is just awesome. I can watch this all das long! :)
I mentioned it on the community post, but I'd love to see more data on the rotation and rpm. I've seen a lot of videos on impact, but almost none on rotational inertia and what it can do to a target, etc. Twist rates vs muzzle velocity and such. If you get time! I'm sure you guys are quite busy.
Great high speed video. It would probably help you guys out to know more about the cartridges you test, even rudimentary knowledge at that. When a guy says the bullet was "probably moving faster" when the velocities are typically printed on the box is revealing. Nothing in this was unexpected but still fun to watch. FYI the fifty has comparable speed to the 5.56. Speed and mass rule the day.
Not to mention bullet construction/composition
Mainly velocity. Ke=.5mv^2
Velocity has an exponential effect on kinetic energy while mass is linear
Most important thing in the video : the godamn sticker
Another great video! I'd love to see the back side of an armor plate as a 50bmg goes through it, in SUPER SLOW MO. Would be really interesting!
I absolutely love these videos. I'd love to see a wide array of shotgun rounds and maybe revisit the same calibers from past videos with different targets eventually. You guys are adding some great informative content to YT. Thank you for that.
The shotguns will add a lot of force but no penetration. They should have free standing plates and then measure how far they get thrown backwards
Absolutely great video! I miss calibers like .338 Lapua, .300 Win Mag, .460 CheyTac and some other hunting calibers. Would be great to see another video with these :)
And a 22-250. I've dented plates with mine. My friend hit the exact same spot with his .556 and it went completely through. It's all about muzzle velocity and bullet type.
2:37 . M855 is going about 400-500fps slower than milspec m193
I'd really love to see you guys do this comparing different types of bullets of the same caliber. Ball vs AP vs API and so on and so forth.
indeed it would be quite interesting to see
Endless possibilities for cool videos with slowmo. Like you mentioned toward the end, you should do this with various shotgun rounds.
The difference between the 223 and the 5.56 in the armor is most likely due to the steel penetrator in the M855. The velocity difference between a 223 Remington 55gr FMJ-BT (I'm guess that's what you used) and a 62gr 5.56NATO load isn't that different if fired from the same barrel due to the higher pressure allowance on the NATO round.
Awesome video! Using the block to visualize the shrapnel was a great idea! Looks like the velocity and energy stats for the 7.62x39 were used for the 54R as well.
Yea it should have been similar to the .308
Your 50 is a beast of a rifle and I knew it was going through that thin plate steel 👍
Very nice camera
Damn that looks like proper example for what happens in space when planets collide. Would be incredible to see two bullets face to face coalition
I started laughing right away on their prediction of the 50cal, like these girls really think the 50cal isnt going to go thru? 😂
I'm genuinely surprised by the rotation speed of the projectiles. Is there a way you could include that data (RPM) in future videos?
Great stuff guys.
Not hard to figure out. Say you have a 1:12 twist barrel, or one revolution in 1 ft. So 3,000 ft/sec would also be 3,000 revolutions per sec, or 180,000 rev per minute! If it's a 1:6 twist, 3,000 ft/sec would be 6,000 revs per sec.
Great video, guys! Would be nice if you listed the weight of the bullets in the "specs" screen.
At approximately the 7:30 mark, that is called the "Schlieren Effect" & "Schlieren Imaging" takes advantage of that effect to study the supersonic shock wave(s) that is/are being formed on projectiles, rockets, missiles, supersonic aircraft, etc.
The moment they said the .50 wouldn’t go through a single steel plate, I was like “uhhh” lmao
The filming and editing was absolutely superb.
Math not so much.
At least with the .50 you went a little crazy.
4067 m/s V0 would be some kind of railgun speed (abt. Mach 12)🤣🤣🤣.
.50s do around 950 m/s max.
Edit:
Also your Indikation for m/s should always be smaller than ft/s😉.
Great video! I would have LOVED if you had included 6.5 Grendel and Creedmoor though! It would be interesting to see how it fragments relative to 556 and 762x39
Love your vids!
I agree. All of the 6.5's and higher with a .308 comparison or comparisons. I am looking to buy a powerful distance rifle with extreme destructive capabilities but with low cost rounds as compared to a .50 . Something with mileage capabilities that is affordable.
My hat's off! I bet you'll see a lot of spikes in the videos's audience retention chart 😉. Beautiful imagery there guys. You're setting the bars so high in the guntube. Keep up the awesome work. Thank you so much.
So.....what about trying a .950 JDJ?
Excellent video ...you've gained a sub👍
4:08 I built a target stand specifically for steel target shooting for my wife before she got home. She shot five rounds of .300 Blackout soft point handloads out of a bolt action Ruger Ranch. We noticed a pancake of lead on the ground, along with smaller discs of copper and lead. She thought it took chunks out of the 3/8th steel plate. I had to show her your high speed video. We also noticed the lead spray all along the sides, embedded into the 2x4 legs.
A true test of the effect of velocity would be hand loads in 300 blackout sub and sonic, 308 Win, 30/06, 300 Win Mag. All with the exact same bullet just at different speeds. That would really compare apples to apples. Lovin the shots that you get. Keep em coming
Great video as always! Other military sniper cartridges like .300 Win Mag and .338 Lapua would be interesting steps between the 7.62/.308 and the 50 BMG.
Add .375 & .408 cheytac and .416 Barrett to the wildcard comparison.
i love your content its actually very entertaining and informative
The reason the plate cracked so much is because it's a Hardox type steel. Very brittle. Use a piece of mild steel plate and you'll get a smooth hole go right through.
It makes sense, having heard .50 bmg ring on plate , but actually seeing that degree of oscillation in something so solid is amazing. But it was all amazing to watch ,thank you .
Cool visual effects! A true test of the 50bmg would have been to shoot it at a fresh spot 2 or 3 inches away from the other impact spots. I know it didn't look like the other rounds did much of anything, but after that many high velocity hits in such a small area, there was likely some significant metal fatigue in that area of the plate. I'm not saying that the 50 wouldn't have gone through, I just think it might have looked different impacting a slightly more resilient part of the plate. Great video!

This is one of my fav slomo channel
13:58 That looks painful. Very VERY painful. The amount of shrapnel that went to that jello looks painful.
Great videos guys. Maybe see what it looks like coming out of the back?
Wait till u gonna hit 1M subs :)
The green tip 5.56 has a piece of steel at the tip, so it can put a dent in the metal when a .223 can't. There are rare cases where a green tip 5.56 can penetrate a steel sheet when a .223 rounds can't, but it's not usually, because of the velocity/power, it's because of the steel tip. It's not really "armor piercing" like many people believe, but it does help it penetrate soft armor better. It doesn't flatten and spread out the energy like a jacketed lead tip bullet will do with soft armor.
Impressive plate. Where did you get it? What's it rated at?
The amount of unburned powder and gasses that exit the barrel has always amazed me. It seems to be inversely proportional to muzzle velocity.
If you watch the closeups of the 7.62x39 very closely there is also a second shock cone off of the base of the bullet.
No surprise at all that the 50BMG penetrated the target. 15:00 "Some of this is going to be metal leaving. . ." Lead, copper and steel are ALL metals.
Overall, very enjoyable!
I just wanted to take a moment to say how amazing your video was! I was really impressed with the quality of the footage, the editing, and the overall presentation. You did a great job of explaining the topic in a clear and concise way, and I learned a lot from watching your video.
I also really appreciated the way you made the video engaging and entertaining. You kept my attention throughout the entire video, and I never felt bored or lost. I would definitely recommend your video to anyone who is interested in learning more about the video.
Thanks again for making such a great video! I look forward to watching more of your content in the future.
PS: I outsourced this feedback to AI.
250,000 feet per second is about 47 miles per second or 170,000 miles per hour.
The bullet can reach the moon in 1 1/2 hours if fired from earth.
That's even faster than a giant meteor racing towards earth from outer space.
That's why it's frames per second.
I believe that they were stating Frames Per Second for the camera. Confusingly that information was given right after the Feet Per Second data.
FPS and FPS descriptions can be a bit of a hiccup for viewers. At least Meters Per Second were given also to help reduce rewinding time and improve efficiency with comprehension.
The photography was outstanding but the info included as captions needed some editing and clarification.
I love this channel so much. I just found it 3 days ago and it has kept me entertained. It has answered many questions I've had
My first visit to the channel. I really enjoyed the video!
Excellent video(s)! Love the new camera! The zoom in on the bullet shadow pushing air is fantastic...I had to screenshot it.
Suggestion: Go to the other end of the spectrum. Air rifles come in 3 flavors. 1. Pump-up pneumatic; 2. Pre-charged pneumatic: and, 3. Spring action. The first two have excellent accuracy without special procedures. The third, spring action (usually a “break-barrel”), is mechanically simple but the accuracy is dependent on the movement of the gun in response to the motion of its internal piston and to how the shooter holds the weapon. The recoil of the action and the resulting movement of the barrel BEFORE the projectile leaves the muzzle has never, to my knowledge, been analyzed. Filming a spring action air rifle at high speed can clear up the mysteries of recoil, barrel motion and shooter grip, all of which greatly affect accuracy. Thanks
There was and maybe still is a gentleman that called himself "B. B. Pelletier" who wrote for an air gun retailer's blog. He used what he called an "artillery hold" to shoot spring/air rifles.
The basic premise was that a person could not hold a spring/air rifle perfectly still and an attempt to hold it hard would not be successful because of muscle fatigue. The core principal of the artillery hold is hold the rifle so it recoils the same way every time it is fired. That leads to consistent motion during the shot release and resulting gilt-edged accuracy.
I would like to see some high-speed video of a spring/air rifle being fired. It would be interesting to see the differences between a hard hold and an artillery hold and if the difference could be seen in the rifle's motion while the piston was hurtling forward.
I've found the video that I've been waiting my whole life to see. That was amazing, spectacular, and fascinating!
This was super cool to watch, keep it up. Also appreciate the conversion to metric units 🙏
Finally a true high speed cam gun tuber! Subscribed !
Glad to have you here!
As a tank warfare enthusiast, I can tell I will like this despite not having watched yet
.243 is an excellent, fast round that penetrates a lot of steel that most other bullets won't. I was really surprised to not see it in the video.
In the final shot, you can see the core of the round slow down and back out of the outer casing, as the outer casing breaks down, the bullet core then passes through at a much lower speed
I had no doubt the .50 was going to go through, it has punched through 30mm of steel at 100m
That freeze frame from the .50 hitting the steel minus the sticker -> Poster = I'd buy 100%! Business opportunity, guys!
Very...very informative video material..... Its mesmerizing how you both can show us the world of micro and nano seconds to us. Thxs
