Shooting YEN Coins from a shotgun - Supersonic Surprise!

[@HoNdA150CRF]

Really liked the information you shared about the missiles. you should include stuff like that more often.

[@KentuckyBallistics]

Very interesting results man! I’m glad the corn is ok lol 🌽

[@StefanAmarisDidNothingWrong]

This one needs more testing. If it turns out to be a viable home defense load, you could have a market on your hands

[@travisfuller2467]

Ingenious.

[@Raagz]

Perfect for home defense really. Considering once sub sonic they separate and become "less lethal". More tests needed to be done, but from what I see here, I believe they are a viable round. You should do more tests with different materials.

[@bradybouteiller116]

I agree need more testing. Different materials. Different loads. Then get maybe you'll make some good money selling them haha

[@vidard9863]

Definitely worth testing, and it seems a vercitle hand load projectile, because it seems that if you load them backwards you get good fast scatter, which may actually keep a tight pattern down range. Or right way out which gives good accuracy, with a sort of select a size slug...

[@john-paulsilke893]

It’s definitely a neat concept.

[@triggerfist903]

This could be such a cool idea for so much stuff. I imagine you could change powder amounts, weights of the disks, and amount of them to make a slug that just falls apart after a near exact distance. Would be neat to try.

[@AtlasJotun]

"And this one's got two pennies in -"No, it doesn't!" I love these guys. I also take 'zinc discs' and 'simulated pennies' to the range as .22lr targets.

[@ph143aaf]

OG and Danny?! Didn't know the Yen had such drawing power lol!!

[@Dsdcain]

That was an extremely interesting video. Loved the technical background info you threw in there. Thanks for all the vids. PS: I also really miss Matv2099. He was so operator, and scientifical (and really funny too).

[@Vanpotheosis]

"Operator?"... What?

[@OGsDangerShow]

Great shooting Danny! It looked hot AF out there! Now to put the 20lb. lead plate in that press and give it a bend!

[@taofledermaus]

lol!!

[@dannyakatrikerred7381]

Officer Gregg If it gets much hotter, we could recast it on the spot 😅. 🇺🇸😎

[@OGsDangerShow]

Thanks Patrick! 😎👍

[@uspavacka]

If you perfect this design, you have a slug that works to approximately 15 meters, but after that is basically harmless. Very interesting.

[@ramjichander340]

man if only mattv2099 would make videos again he was awesum. great video Jeff and please pass on my thanks to mattv2099 for making this video happen

[@taofledermaus]

Yeah, keep hoping he'll surprise us and post something

[@Tekdruid]

Hey, you invented the real life version of a videogame shotgun round! Absolutely lethal at 1-4m, sort of hurts at 5-10 m, and then basically turns into hand-thrown popcorn.

[@UninstallGoogleChrome]

And to think people keep saying the Yen is weak right now.

[@skepticalbadger]

Immortal Cactus Well played.

[@Unmannedair]

I wanna see a supersonic dollar bill now...

[@timma827]

This is fascinating, i love the wonky weird ballistics of it all! id love to see some tests of different stack sizes and different materials like brass, copper, lead and steel, or even just different thicknesses of Al. Seeing the drywall stop an individual coin makes me think it could be a fantastic home-defense type shotgun round if you could get some consistency in when the coins separate.

[@Keldor314]

I strongly suspect they're separateing as they become subsonic, in which case it should be pretty consistant. Just adjust your powder load to control exactly where this happens. Also, your barrel length is important, meaning that the point of separation would vary from gun to gun.

[@Raagz]

I think they're perfect for home defense. When they go sub sonic and separate they become "less lethal" so if you miss there's a chance of no loved ones injured.

[@Tolenar]

These are awesome. I would love to see this concept taken further with brass or zinc as you mentioned at the end.

[@OGsDangerShow]

Next time shoot a stack of 24 karat gold krugerrands!

[@Auriam]

Officer Gregg trolling your own channel I see! ;)

[@timexkills65]

Hey I live in Fresno and made a slug I’d love for you to shoot or maybe one day meet up ! I love the videos man . Tao fladder mouse ❤️

[@soylentgreenb]

Just the one is already heavy enough.

[@der_municycler]

Do you have the money?

[@fuzer909]

Its been revoked.......I had to say it OG.

[@PsychoticBovine]

I like that they look like tiny woks in a windstorm. Wok you like a hurricane!

[@theusher2893]

Great now that song will be going through my head all day XD

[@cornspace]

Thank you for not harming me in the making of this video.

[@2tommyrad]

Paint em OD green and you can use em as helmets for GI Joes.

[@Mr.Unacceptable]

Use wheel weights from a tire shop. The lead is a lot harder and stiffer. They combine the lead with linotype, which is 11-12% antimony and 3-4% tin.

[@kasper7574]

By golly i think you've just invented one of the best home defence shotgun rounds in the world!

[@ianmacfarlane1241]

Paul Harrell was shooting dimes a couple of days ago, and now you're shooting Yen. Patreon must be working well😄. Great video - and fantastic impression of OG by Danny - totally nailed it😄.

[@taofledermaus]

Yeah, just learned of Paul's video the other day. lol

[@cross3052]

Yen coins are one of my favorites. They're beautiful coins and apparently make for some interesting projectiles when properly shaped. I especially liked how the stack separates as the velocity drops off. Very cool video.

[@ashIibabbitt1111]

"Two zinc discs" Way to expertly dodge the law about defacing US currency.

[@taofledermaus]

because smashing penny machines at every tourist spot isn't a thing, huh? lol

[@everettknight8201]

If you made the penny to look like a dime than its illigal other than that you can do what ever you want with your money many poeple make rings from quarters or draw lincon into a zombie

[@bitfreakazoid]

Interestingly, I learned recently that it only applies to coins, bills it would be illegal.

[@everettknight8201]

bitfreakazoid oh on my brother comited a federal crime on video

[@aaronwilson9261]

I think the Australian 10 cent coin would do the trick pretty well if you got them into shape. They are made of 75% copper and 25% nickel

[@spcpitts]

Riding each other like la traffic. Good work making these, shooting them and thanks to mat for sending them

[@kingginger3335]

WOO INDIANA! I'm from Indiana and you're right. That background looks exactly like home

[@packardwitt1682]

I love all your videos. Thank you and please don't stop making some of the best videos on KZbin.

[@SurvivalRussia]

This was super awesome :)

[@taofledermaus]

Thank you Lars!

[@whateverworks6502]

In your hunt for the perfect home defense round you have finally found one. It loses energy at around a dozen yards when the coins go subsonic while it is lethal at close range

[@Thorsaxe777]

Jeff, Danny and the OG. You guys started me off in shotgun loading. I find that your show is informative, interesting and quite funny. I will continue my support in Patiron. Thanks for such great content. Thor's Axe.

[@Kumquat_Lord]

If you were to make them, I'd recommend putting a star shaped hole in the front, with cut lines going close to the edge, or just some break points along the edges so it breaks apart upon entering to cause maximum energy transfer

[@user-ib8oz8gp7c]

Mattv2099 come back

[@A-CAT-47]

I'd love to see you guys try this design on some washers

[@AhnkoCheeOutdoors]

I bet they would make a wicked whistling sound when fired.

[@andyspark5192]

try it again with different coins weights in front the heaviest, than middleweight, then lightweight 2-2-2

[@ArtisanTony]

Matt is rich enough to shoot money :)

[@taofledermaus]

who is matt?

[@ArtisanTony]

mattv2099 :)

[@secondswell]

ArtisanTony yea he makes loads of money off of all the scientific operator operational operations he does, real hush hush stuff.lol

[@kyler-pj2vy]

ArtisanTony 1 yen is about one penny

[@ArtisanTony]

currently it takes 112 yen to make a dollar so it is close :)

[@AhnkoCheeOutdoors]

When I was a kid living in Japan in the early '60s 3 yen equaled a penny. A penny could buy you allot in Japan back then. They're close to equal now. This is the Japanese version of the mythical "Billy-the-Kid shotgun round" but replacing yen for dimes. A dime back then (1880) when allowing for inflation was worth the equivalent to $2.47 so a stack of 10 dimes would have been worth $24.70. I just can't imagine a guard loading dimes for ammo when way cheaper to just buy a box of shotgun shells.

[@ponthis1]

Danny wearing that Kentucky ballistic shirt. I think you just may have made Scott's day.

[@buffalosoutdoors]

Larry Thompson I like that these guys support other gun channels. I'm sure Scott appreciates that too!

[@john-paulsilke893]

And as usual the Kentucky Ballistics shirt is covered in sweat patches. Not sure which one will net you a higher auction bib, Danny’s game worn jersey or Scott’s? 😊

[@LordSlugsPlug]

BGKY FOR LIFE

[@ktm42080]

The emperor called, and he is pissed! He wants his coins back.....

[@edifyguy]

This is a very interesting concept. I do believe you just developed a top-notch close-range frangible slug. You do need something denser (zinc discs for example :) but then you've got a slug until it goes subsonic, which disintegrates into less-lethal garbage as soon as it goes subsonic, and the best part about that is that it doesn't have to hit anything to disintegrate. Carefully calibrated loads with carefully selected discs could break apart at predictable and repeatable distances so that anything outside that distance was relatively safe, and anything inside that distance was reliably stopped. Great work, and this could be the next big thing!

[@rrditch]

I'm glad that this was done. A few years waiting to see if it could be done.

[@Billthebaker420]

Nice video guys, still the best KZbin channel!

[@hanfpeter3742]

You know you are one of the best youtube channel around when Nicola Tesla is your patreon.

[@nanaki-seto]

you have to try with brass and copper as well as lead. I thing thin lead will deform in flight

[@nonimport-ante]

you should try the stack of domes(no idea what you'd make them from) again but with a tiny dab of melt wax between to hold them together. my hope would be that they act like a slug until they hit something then break apart and scatter thus doing horrific damage to flesh without risk of over-penetration.

[@RussXnimbusX42]

It would be really interesting if you did a similar round with lead discs. That way you would increase the mass of the round to provide more force at close range, but the shape would cause it to slow down quickly. You might also need a plastic hemisphere in the rear to prevent the deformation of the domed projectiles upon acceleration. Or, instead of all lead, do a sandwich of lead and thin plastic discs so that the lead discs wouldn't fuse to each other. I love the exotic rounds that you shoot, but for home defense, this is one of the neatest things that I have seen! Much love!

[@forzerotoo]

I was going to ask in the beginning, “I miss OG!!!” Glad to hear his voice in the background later on. 🤩

[@thespicemelange.1]

I think the carpet had something to do with that stoppage. But who knows. Yay! Science! Always enjoy your videos! Keep up the good work!

[@FrancisSims]

Seems like a good round for shooting where you don't have a lot of space if they split apart after 15 yards and don't do much damage

[@charlesmiller6826]

Definitely worth exploring with different materials and thicknesses of disks

[@base935]

Super excited you partnered with Kentucky Ballistics!

[@mislam313]

well, you finally solved Admiral General Haffaz Aladeen's missile shape problem.

[@saartal4524]

Wow... I love the idea, very creative way of turning a disadvantage to an advantage and wonderful shooting. Perfrct score and I really loved the idea of brass hemispheres... yet anoter brilliant video....

[@ruthlessrubberducky5729]

I'm a definite aerospace nerd. Keep doing these research-based videos.

[@mcramen4488]

Well I'm sure that I am the only who watch this as Japanese from Tokyo, man, cool video!

[@taofledermaus]

gracias!

[@ronniepirtlejr2606]

Very interesting concept and results!

[@buffalosoutdoors]

Very interesting. The ones that stayed together were very accurate. By the way, I saw a bird in the background and your fingers look funny.

[@taofledermaus]

I was expecting them to separate, but not have much spread - unlike dimes that have like a 5 foot spread at 10 yards. lol

[@whataboutbob9786]

TAOFLEDERMAUS I've shot dimes before, had about 20' spread at 15 yards. One day, some kid with a metal detector is going to go nuts when he finds that spread.

[@45CaliberCure]

Yes, but he would have to leave his own yard. :) Not likely, these days.

[@Baudelier42]

Looks like these would make for a very effective home defense round.

[@eVVigilance]

Do again with heavier discs. Bismuth maybe?

[@photolabguy]

I think the coins look like fried bologna when it bubbles up in a pan.

[@taofledermaus]

lol true!

[@aeoo371]

photolabguy yes it does. A fried bologna sandwich sounds good about now.

[@bobc4718]

Brings new meaning to the term " money shot "

[@dmitriykolesnik4462]

Total we have a munition with a programmable distance of defeat. Very cool.

[@larryking606]

Good Day , Jeff Another Great Video ! , You indeed are a Man of many Talents ! I see more of your many things stored inside of your mind Almost every time I watch ! This time your knowledge of Aerodynamics is right in line with your other talents ! And once again , Such a pleasure to enjoy your videos ! Take Care and Be Safe

[@smoothvirus]

6:37 Yen coins: "Do the Loco-motion with me!"

[@StreuB1]

The two Yen that separated from the stack once passing through the transonic region doing little damage. This was likely due to the coins being shielded from nearly all drag but once they became unshielded by the oblique shock envelope. They were exposed to the full on subsonic drag; so their acceleration (-Δd2r/dt2) skyrocketed instantly. This sudden -Δa caused the energy to plummet sapping a lot of its forward momentum. Sudden shock in acceleration (3rd derivative 'Jerk') causes massive losses in energy at higher velocities.

[@crpope10]

I saw a commercial in this video today. Yay!

[@Kratos_God_of_50_BMG]

Aerospace Nerds unite!! Interesting idea Jeff, and great shooting Danny (rockin’ the Kentucky Ballistics shirt!) as usual 😁

[@PeterOekvist]

A litteral money shot. Good job!

[@44WarmocK77]

Ah yes, that beautiful image I had in my script about gas dynamics ... love it!

[@fishncopper4521]

Your explanation and photos were fantastic. The self stabilazition in liquid was interesting. Thanks.

[@taofledermaus]

thank you

[@theoldkhajiit5304]

Very cool. A 'friend' of mine made a $1.20 shot with dimes and it was an interesting pattern on 3/4" plywood from 10yards the pattern took up the width of the full sheet of plywood and every dime went through. Some on end others flat. It was a cool experiment. Thanks for the video guys!

[@ders972]

Funny fingers made me laugh... you rock man!

[@taofledermaus]

lol I get a few finger comments every day

[@ders972]

TAOFLEDERMAUS Those ladies are thirsty!

[@taofledermaus]

you don't realize how many weirdos there are until they comment on your videos! lol

[@dylanzrim1011]

Ders972 the ladies must be pretty desperate if they're getting hot and bothered over fingers that fit in a 12 gauge 😉

[@SpLiC3]

Great vid as always chaps, love the science mixed in with the fun, hydrodynamics, hydrostatic shock etc.

[@taofledermaus]

thank you for the nice words!

[@mealex303]

Please jeff take this idea further add a point to the underside to make it look like a thumb tack to see if that would stabilize a single disc and only fire one thick one at a time?

[@roscop.coaltrain9440]

Jeff and the tfm crew. You guys are awesome. Keep up your good work

[@jeremybackman2782]

Nice clean holes, very close to each other too

[@o2wow]

Numismatic rocket science.

[@victorwaddell6530]

When I was stationed in Japan back in the early 90s 1 Yen coins had a hole in the middle . We often used them a washers . I wonder how differently the old 1Yen coins with holes would compare to these newer ones .

[@lukeh9199]

I'd really love to see more follow-ups on this, with different materials and some lined up ballistic gummy bears.

[@DaveTex2375]

Superfantastic!!! Great Job TauFleugelmeister! 🐸👌

[@DaveTex2375]

Supersonic Wake is my favorite 80's Alternative cover band!

[@AZREDFERN]

Do it with domed washers. See what effect the center hole has. Maybe even fire it backwards.

[@piranha031091]

Did you see that bird with funny fingers in the background?

[@cheesechiu]

Now we need a cyborg shotgun arm to shoot these, GITS style.

これを日本でやったら硬貨の加工は犯罪ですよ的なコメントであふれそう

[@wcweaverjr]

I can tell you from a recent negligent discharge, that drywall does NOT stop bullets!! My .45 acp hollow point went through 3 interior walls exited the house through the siding, then entered my neighbors house through his siding and then went through 3 interior wall of his home before finally finding a 2X4 and coming to a stop. I just finished the paint job on the repairs to his home this evening. Luckily we're friends from our service days and even the police said it was up to us if we wanted to involve the insurance companies. Thankfully, Bobby let me fix the damage myself.

[@kimchionruis]

This is actually a pretty good idea. As another poster, suggested, even thicker Al discs may have improved/more consistent performance

[@TheKentuckyPatriot]

So cool seeing you wear a Kentucky Ballistic shirt. Scott is such a great guy. I have one of those shirts myself :-D

[@jeffhiggins4478]

Maybe try using some different coins. Pesos have some heft to them, but I don’t know if they’ll fit after going through the press.

[@Biped]

If you stacked those things backwards, you might be able to force separation as the column wants to stabilize. Although that would make that thing somewhat of a pepperbox. just an idea.

[@DaveC2729]

I haven't believed that drywall would stop a bullet since I was 14. At that age, I learned that it wouldn't stop my fist. Of course, it's a bit of an assumption that a bullet is harder to stop than my fist, but I think it's one of the safer assumptions one could make...

[@juangonzalez9848]

Wonder how a rifled barrel would make them act. Would they be stable longer? Or would they immediately scatter to the nine winds like buck shot in a shot cup does.

[@matg919]

Cool idea would love to see more testing on blunt nose projectiles.

[@jeffw1246]

I just saw a "Little Tony" and bought it today. Fun little compact gun. I gave up on Lee 7/8oz slug for accuracy out of smoothbore or rifled choke tube. Going bact to .690 round ball which shoots better. I'm going to try the paper patching like old black powder loads to get them to around .730 to see if they improve even more. 55w weight writing paper per Lyman cast bullet guide. Just for fun low recoil loads. Try glueing pages of thick books to make them solid. Stack 3 about 4in apart and hit them. Even light loads do impressive damage with .690's.

[@CarpeNoctem135]

Try making the domed disks out of various materials and find out which ones give the best results
