[@TesserId]

Hmmm. There could be differences in the alloys, or not. Hardening could be just a change in the crystalline structure. In this context, that somehow becomes much more interesting.

[@Silshadnic]

A suggestion: When you guys film impact footage of things colliding really hard, have a simple thermal camera at another angle to see the difference in temperature the impact created. The thermal camera doesn't need to be high framerate, it'll be already interesting to just see how much heat got generated after the impact

It's fascinating to actually see it, I'm not sure why the bullet continues to spin since I would have assumed nearly all momentum would have been absorbed by the target, does make me curious what a smooth bore projectile hitting a spinning target would do...

[@stevejones4618]

Love the way the spinning round hits the plate and compacts and stops rotating but starts rotating again as it relinquishes contact with the plate. The kinetic energy of the spin remains as potential energy until it's free of the plate and converts back to kinetic rather than the spin just being stopped and it rebounding straight back. Amazing.

[@TheInfinityMaster1]

10 years from now, Gav is gonna be like "Remember when we had a camera that shoots at 1.7 million FPS and we were so proud of ourselves back then?" And Dan is gonna be like "Yeah, I can't believe we were proud of such rubbish camera when now we can film at 20 million FPS! lol"

Will there ever be a limit on how fast these cameras can be made to shoot? Probably pointless to ask when I don't understand what mechanism allows them to shoot so fast in the first place..

[@JustSomeCanuck]

Actually, cameras capable of 25 million FPS exist right now. They use a high-speed rotating mirror to direct the light to a series of digital image sensors, so each frame is captured by a different sensor. en.wikipedia.org/wiki/High-speed_photography#Rotating_mirror

A thing that is under appreciated about steel is how broad the term actual is. The term is used for carbon steel, alloy steel, and stainless steel all of which have a wide range of properties depending on how their manufactured and small or in certain cases large changes in how much and what type of materials are added to the alloy. The range of strength in steels goes almost two full orders of magnitude and they can have wildly different chemical, electrical, magnetic, and mechanical properties as well.

Seeing how slow the bullet moves at those speeds and then seeing how fast the debris spreads away from the impact point is something else.

4:00 Alternate theory, Seeing that the "sparks" seem to be coming from a point smaller than the petals, I think that there is a good chance these are not sparks at all but rather the air caught within the hollow point combusting from the rapid compression on impact and exiting through the gaps between the petals. But that's just a theory 👀 Edit: You can also see that the light is coming from the space between the petals rather than the petals themselves if you watch the following frames where the bullet expands and compare the petal locations to the light locations.

Not to mention other channels that go into professional swordplay and such If you know where to go KZbin is a fantastic resource

[@soldat2501]

At indoor ranges they go on and on about the ventilation and lead inhalation. For 35 years I really didn’t know what they big deal was. Seeing that 30-06 turn to lead powder was fascinating. NOW I get it.

[@CGT80]

There is also lead compounds in the primers in ammo, which is even worse because it burns and turns into a gas. You have to eat or breathe in the lead for it to be harmful. Bullet casters have had high blood lead levels and found that no longer going to an indoor range but continuing to cast bullets brought their levels down to normal. Casting with decent ventilation isn't as bad with just a pot of melted lead because it isn't heated the same as the gasses from a gun firing and there isn't dust all over. I'm glad I have a private outdoor range that I belong to for the lead, noise, and a bunch of other ways shooting outside is better.

[@TrentFalkenrath]

Yes! That shot with the super sonic shockwave in the air, that may have been the coolest thing I've ever seen from you guys. Friggin' awesome.

[@petekaiser8856]

the .308 round makes me think of the effects of cannonballs on wooden ships. Now THAT would be a kick ass video, bloody expensive but worth it.

[@johannesbohm6458]

They already have shot cannons at diferent things a couple of times. And while shooting at an actual ship is a bit too expensive, a 1x1m wooden wall would be practically the same...

[@MGSLurmey]

I'm pretty sure they have shot a cannon at wood to show the spawling that is the actual killer in renaissance ship combat.

[@andersjjensen]

This was a 30.06 which has significantly more powder charge behind it than .308

[@zigamikeli7233]

[@Beard_Man_Rob]

That piece of steel you found appears to be a "static steel" target, which is most likely hung from a 2x4 piece of lumber (cheap and commonly available), which is then set in a steel stand of some sort. That piece is likely AR500 or AR550 steel, which is essentially armor plate and extremely hard. These are commonly set up in different arrays for a course of fire in a shooting competition, like Steel Challenge.

[@sheepherd9173]

I was just gonna ask about that, I didn’t expect such a difference in steel but I guess I should’ve after seeing steel challenge targets stand up to all sorts of hell.

[@eleanor7748]

[@Big88Country]

Awesome job guys!! Dan, I am a Marine Corps expert rifle and pistol shooter and you are an impressive shot my friend! Great video!! I learned that what I have been hit by many times is most likely the jacket from the round and not part of the bullet itself.

Awesome stuff! Couple things I'd like to see, not sure if you've already done them- Overinflating a tire until it explodes or pressing a glass or obsidian ball(not a ruperts drop) until it explodes like on hydraulic press channel or bullets through random other stuff(fruit, plastic, water tank, can of beans, iPhone, etc)

[@Ryzawa]

I love how they still have the quarry as their setting, not many KZbinrs out there filming in the desert like this, excellent lighting ofc. Glad they got a tracer round, always wanted to see what they looked like in slomo, I believe they usually show more light at range though. I love how you guys still managed to capture 1 in a million shots to this day as well, always something rare and unexpected happening. Glad there's multiple angles as well.

[@andreasg.5316]

Vielen Dank für diese aussergewöhnliche Erfahrung !!! Dazu habt Ihr wirklich Entertainment Qualitäten die man nicht oft findet . Respekt und weiterhin viel Erfolg !!!!!

[@sailorgeer]

Amazing footage! Regarding the different behavior of the two steel target plates, it might well be chalked up to different hardness as you suggested, but (as a structural engineer) I suggest it might also be due to different “toughness” or ductility. A brittle steel (low toughness) will fracture once the deformation or strain reaches a certain level, whereas a ductile or tough steel will deform a lot more before it fractures. In steel specifications, fracture toughness is quantified by the Charpy test number. High Charpy/toughness is a desirable property of steel in some applications, for example in low temperature service which can make regular steels fracture in a sudden brittle manner when a more gradual, ductile failure mode is desired. In structural engineering a ductile behavior is more desirable because it yields and deforms prior to failure, giving advance warning that the material is overstressed. In contrast, a brittle material might look fine up until the point it suddenly fails.

[@billj5645]

The steel plates manufactured for target shooting are usually made from a steel they just call "armor plate". I would like to know what that means in terms of yield strength. I was also wondering if it is just a higher yield strength steel or do they put other elements into it to change the toughness as is done with steels for knife blades and industrial tooling. (I'm also a structural engineer.)

[@Sableagle]

@@billj5645 The only specification I've ever seen is "AR500," which I think is an abrasion resistance thing.

[@jfess1911]

What we saw with the rifle bullet is sometimes called "plugging". The transfer of the energy to the plate creates enough force that a plug of the steel is sheared off.

[@alexdrockhound9497]

Ar500 steel was the second target, AR stands for Abrasion Resistant. Their first plate was probably some generic mild steel.

[@CGT80]

@@billj5645 There are different grades of AR steel- 400, 450, 500, 550, etc. The number is the average brinell hardness and you can look up charts for the rockwell hardness. Lower grades can be easier to bend for use on heavy equipment while 500 or 550 is preferred for targets. 5.56 and 223 rifle rounds can do more damage due to the higher velocity than 30-06. Bullet shape and velocity play a big part. My 460 magnum revolver packs the same energy as 30-06, but a huge hollow point bullet with more weight and less velocity makes a bigger dent or dimple in steel than the rifle. 460 mag is around 2400 fps for a 200 grain bullet and about 2000 fps for a 300 grain bullet. Average 30-06 bullets are lighter but faster and of course 5.56 averages 1/3 to 1/4 the weight of 30-06 but at higher velocity.

[@lauxmyth]

There is always so much more to see in these. The rotation even after impact. Amazing.

A high frame rate FLIR would be fun to see. How hot are the sparks when the bullet hits?

I think I really loved those last few 30.06 against the hardened steel plate because I kinda loved watching the back of the copper jacket just smoosh the lead; so at the end you just saw the flattened copper get kicked off the plate and a small little lead pancake just behind it.

[@NoChance345]

The shot of the rifle firing might be my favorite of the video. They were all awesome but being able to see the bullet slowly leave the barrel was amazing to me for some reason.

[@muxpux]

I was trying to film something the other day in slo mo, and found myself thinking… “how would the Slo Mo Guys get this shot.” It was the snow swirling in the wake of my tire while driving through powdery snow. It was beautiful, so much going on, but hard to film with one hand out the window. 😂

[@oculusangelicus8978]

If you guys take a hard look at the returning copper jacket, it has been turned inside out because you can see remnants of the lead on the inside of the jacket, which is now on the outside. As far as the white target it is made from AN 500 armor steel and the plate of steel you used is made from mild steel, there is a big difference between mild steel and Armor steel not just it's hardness, if you were to take a regular high carbon steel and harden it as hard as you can, the steel would shatter or crack when the bullet hit it. AN500 is a special kind of steel with various components, basically it is an alloy steel. the base metal for AN500 is Iron, then Carbon, Manganese, Phosphorus, Sulfur and Copper. Steel isn't the base metal of AN500. Now that you've seen and felt the power of the 30.06 round you can have a better idea of what the Germans faced in WW2, when ALL of the rifles and BARs used in WW2 were in the 30.06 caliber round. It packs a powerful punch, and you now know why those Round targets are put on 2x4s or spring mounts because the power of the 30.06 just breaks things. Thanks for another great video guys! Cheers!

[@tombryant4518]

AR ( abrasion resistant) 500 ( the hardness rating) So it’s AR500 not AN500 steel. It’s used on bucket wheels, grader blades, excavator buckets etc as well to help reduce downtime and increase run time.

[@BertRowe-b3l]

@oculusangelicus8978 AR = Abrasion Resistant. Which is classified as a low alloy carbon steel. Before writing several paragraphs about a thing, you really should talk to someone who actually knows. 5 minutes spent on Google with no relevant background isn't too useful.
