20mm Air Rifle on Helium

This is my first video on the long awaited 20mm air rifle, Brent Hoag built this canon for me and were now testing it out and seeing what it can do, its all a very exciting journey, I hope you like it.

[@patrickgermond2750]

I need one. When friends come over I can ask them, "You wanna shoot my pellet gun?".

[@Bigbopperairguns]

Right!

[@thomasfrye8996]

I'm just starting to get into these are guns and I have to be honest I'm really shocked at the report it gives off. It sounds like a regular rifle. And the power is unbelievable

[@roysmith7087]

Hog explosion 💥. That's monstrous and destructive. I'm loving it

[@globetukker2510]

[@masondawson4061]

I can confirm this phenomenon from my limited testing helium in a Drozd Blabkbird. When I played with the stuff I used two regulators. The first was 1K psi output. I didn't have a chronograph at the time, and assumed my 1600 psi regulator would get me even faster. My 1600 psi tests were racked with problems. When I did get the bird to shoot right it was around 1100 fps on the Chrony, but I truly believe it was faster with the 1K regulator.

[@docskate4312]

This video, Mr. Hollowpoint, the gun and the projectile - all made of pure AWESOME😁👍

[@ConnerHolifield]

Love the extreme 82cal and the shoebox compressor

[@supidat6871]

I'm liking the HOGSMACK!

[@chuckpotter1036]

I would guess the gun has a single stage regulator, as the input pressure goes down the output pressure to the rifle goes up slightly .

[@Mrhollowpoint1]

No regulator, just a airtube with a valve, the hammer pushes it in and the air pressure closes it.

[@bub_lite_6361]

From what I'm seeing you might try a heavier hammer spring to overcome the valve at higher tank pressure.

[@luishernandez-zk3hn]

mr.hollowpoint 1 you create the 20 mm caliber rifles and you also create the warheads of that caliber I would appreciate it if you answered me thanks and very good videos

[@thequigley72]

luis hernandez, thanks

[@extreme.4576]

Roberto, that lead mushroomed to a HUGE Silver Dollar chunk of lead!!! Can't wait to see a kill. Best of Luck!!

[@MissionaryInMexico]

Airgun with balls. Elk, moose and bear.

[@MrExplorer1965]

Add some more pure lead to your bullet mix. It looks like it's fragmenting before full mushroom..... But you got some cool ass sh*t going on there !!

[@chrispawlina7500]

Did you know Mr sexy, that helium in a sub 12 rifle produces over 30 ft lb !! AWESOMENESS 👶 BABY

[@90ForLifeTeam]

Looking forward to your findings on the heavier hollow point!

[@markbreidenbaugh6033]

3700psi = Freedom. That's what I saw anyway.

[@macswanton9622]

That's like 3/4 of a foot/ton. Sh!t, you ain't gonna call that "backyard friendly" :o)

[@erockrocket72]

WoW Congrats. That helium rifle is devestating.

[@lukes-uf4bc]

what niceee! and what terrifix kick and power!!!! that rifle is great!!! 1150 grains!!!!! wowww!!!

[@pdoug54]

Holy crap! that's one badass pellet gun!

[@ronwhittaker6317]

never seen a pumpkin juiced before 1st time for everything

[@tarmacdemon]

You sir is having far far too much fun .............I'm green with envy lol great video .

[@somerandombaldguy5296]

"Overkill?" Never heard of it...

[@neilplace7916]

You may have an entry for the worlds biggest pumpkin explosion for the Guiness book of world records. Absolutely stunning exibition of air gun power.

[@johnwallace9002]

You should try hydrogen because that is what we use in our Lite Gas Gun at work to get 20-30 thousand feet per second. The Piston pumps the Hydrogen to around 20,000 psi and it's safe without oxygen. I don't know for sure but hydrogen should be a lot cheaper than helium. Hydrogen can be made at home but helium is recovered from oil wells.

[@3347861]

That thing's a cannon!

[@Gollammeister]

My god the power in that slug jeez

[@trondyne3513]

This is a very strange way to make pumpkin juice...

[@willierice7138]

Really cool gun, never thought of Helium..

[@garuga0777]

You could try making the chamber with plasma electrodes and see if that increases the pressure. Since helium can be used for hall effect thrusters there's probably a way to utilize that principle. Plus you'd make the world's first plasma rifle.

[@renikun6243]

and one doesnt need much of a voltageto turn helium into a plasma.... turn an air gun into a plasma physics project lol

[@N2RI1]

would like to know more about this gun. retail price, where its made/sold, smooth bore or rifled, is air regulated or valve/trigger adjustable, remote tank teather available and weight of gun etc. would make nice combo rifle/shotgun if smooth bore.

[@Romans--bo7br]

N2R11..... First of all, now in 2019 - the .82 cal (20mm) is NOT available, but all the others are, from .257, .308, .408, .457, .50 and .72 cal. The Base price for the Nitro 500 Express is currently $1,880. to give you an idea of price. The .257 is offered at "custom pricing"... so would have to call him for that. All of Extreme Big Bores air rifles are in the 4 digits (not sure about the .257 cal. in that regards), check Brents site for the specific caliber and pricing... also, the prices listed are for the "standard" rifle, any additional extras, including different stock, etc will raise the price accordingly. These are all custom made in MI., "in house" and are ordered, made and sold directly from Extreme Big Bore Air Rifles (Brent Hoag). There are a few "out-side" dealers for his guns, But best to contact him directly. The barrels Are Rifled, Non - Regulated, as far as tanks and tethering... whatever You can put together yourself or pay to have done for you... check with Joe Brankato at www.airtanksforsale.com/ - he has the largest selection of air tanks, fittings, hoses, etc, for PCP Airguns... and EVERYTHING he sells, is 100% made in the USA.... Absolutely Zero "copies" from anywhere in Asia or anywhere else.

[@timburton1715]

Awesome video... thanks 🙏🏻 for sharing.

[@chrisp.5272]

This is awesome! I want to build a custom 20MM Air Rifle!

[@thequigley72]

Email me for a barrel.

[@kiaas]

old video yeah, but one thing to note is that the speed of the round should be affected by the speed of sound in the gas propelling it, so a hot gas will shoot faster than the same gas at the same pressures but lower temperature. It's why you'll find things like nasa's micrometeorite research light gas gun having a setup to heat the light-gas before firing it.

[@miksal26]

Isn’t helium hellishly expensive and becoming scarce?

[@EricHendersonAdventuresAfield]

Best video yet

[@ronaldmoffett3498]

Really enjoy your KZbin shows!

[@HolyBibleOpen]

Wonder what helium would do to a Texan 257 122 grain bullet with a 4500 psi super valve..

[@MRT_H]

Awesome! Like the number testing and the fun testing!

[@picvan]

Are your telling me after impact your hitting things with a golf ball of lead? I approve!

[@Sonofaguninmo]

How do both 20mm bullets perform on just regular air?

[@DaveShooter1]

Hi Bob Dave Smith here. Been a few years ole buddy. Hope all is well for ya. I am getting back slowly into Airguns. Good talking at ya ole friend.

[@jmartin9059]

That looks like a great candidate for Zinc or ZAMAK alloy hollow point pellets or slugs.

[@timsmith9169]

I was a gunner on a 20 mm Vulcan 6500 rpm .would love to have one of these

[@randomdude1786]

love your videos, very entertaining. I love the custom built stuff you get a hold of.

[@GRAYJ6000]

I'm new to air guns but would like to invest in one for backyard plinking. I own a Tig welder and was wondering if I could use my compressed Argon tank to fill a PCP? Have you done any experiments using other gases besides Helium? I would like to avoid purchasing a hand pump for a PCP rifle.

[@keithjurena9319]

Forget it. Argon is heavy so speed of sound is low so no advantage. Helium is light so it has higher speed of sound. I use a Benjamin hand pump that I modified to take absolutely dry air at 20 psi. This supercharges the pump to where only 20 strokes takes my Marauder from 2500 to 3000 psi.

[@radar2119]

GRAYJ6000 Argon is inert, so you could at least tinker.

[@dallasanderkin7134]

Hog knocking 20mm love it when is it in production??? Cant wait till i can get one

[@lostforevermore7150]

He is shooting cast aluminum alloy bullets good luck guessing the alloy but it would be cool to have that awesomeness in. 357 caliber

[@grunter1389]

Make a life -size Ballistic Gel Hog . . .

[@enterthehunter7336]

well with this I could have the adequate power for coyotes and have the flexibility of an air gun as far as where I can shoot although this things upgrade in power has to be taken into account and there may be some explaining to do that it's an air gun just a really powerful one as to why it's so loud and people think it's a firearm I suspect the price tag on this is somewhere along the lines of $3,000 or more but it is most certainly an awesome air gun

[@KauaiSeeHorse4]

$3,000+ for the Gun. Then another $1,000 ? for the Carbon fiber tank, and God knows what else for ALL the other stuff in his basement ? ? ?. Hell I bet it would bring down a Bull Moose with ease. Still a nice DREAM :) ...

[@stevemichigan541]

1800 according to web site. 1700's for lower cal

[@Mrhollowpoint1]

Tedd explains at the end of the movie that he gets helium from the local welding shop, you need to call around your local area.

[@kiaas]

I was watching it and wondering if you had the helium pre-pressurized, or if the higher speeds were perhaps a result of a compressor being used to refill each shot, and it getting hot and heating the helium more and more on each refill, as I mentioned in another comment speed-of-sound affects what you'll get out of a gas at any pressure, and a hot gas will have a higher speed of sound, even at the same pressures, than the same gas when cold. (but I haven't gone and looked at just how much hotter you need it to be to even see a difference.) on a side note, I'm also curious about effectiveness or viability of mixed-gas propellants vs standard air,nitrogen, or CO2. Like Nitrogen/Helium as the safest things to mix.

[@deeremeyer1749]

Where you'll NEVER find ANY bottled gas with a "full" tank pressure in excess of 2200 psi. Much less the "4400+" psi this clown is claiming as his tank pressure. Hooking a small cylinder to a big tank doesn't pressurize the smaller tank to any pressure higher than the...tank pressure. That's called Pascal's Law. If you'd have taken/paid more attention in science and/or shop class you'd know how much bullshit this all is.

[@raymondj8768]

that rifle is fkn so sweet bro holy shit i cant believe what your doing with it lol great job !

[@bimmyby3]

DEEREMEYER1 17:58 hè give the answer to youre question

[@HaraldSangvik]

Should be easily able to transfer it using a hand pump with a very small diameter piston and two check valves. If you start at 100 bar inlet pressure, you're pumping 100 times more gas per stroke.

[@NOREENULR50BMG]

Could you redo a helium video where you test different hammer weights, spring strengths, and pressures? I think much more velocity with helium can be achieved in your 20mm @ 4500psi if you've got the right valve, hammer, and spring. You should be able to get over 1000fps with it.

[@HolyBibleOpen]

impressive. 3700psi 834 fps and 1776 fpe. wonder what a Texan 45cal would do.

[@N2RI1]

lots of youtubes tell about the Texan specs. about same FPS only with air, and about 500 FPE with 405 grain slug and 3 good full shots per charge. could use a remote backpac cylinder for more shots in field with a PCP gun with proper hookups like the new 'Preist' 30cal does as an option. also bullpup design makes for shorter liter carry Rifle plus shroud forless sound. the big bore airgun world is growing daily in many ways Tech, performance, affordability. and like everything when more sell cost goes down. we need to look at practicality for hunting with weight limits, Ammo and air availability and cost of buying/using an PCP airgun with no more cost etc than powder burner of similar capability. least amount of Lead, Air tank, gun size & weight, costs that meet most hunters needs. these 'Monster' airguns are cool but not practical for hunting. 45cal has been max for powder burners since the Buffalo and Black powder went obsolete. lets focus on what works and improve on that where posible then add new features like quicker fireing/reload like the rotary magazine types.

[@HolyBibleOpen]

N2RI1 Yes, The texan is nice but want more than 1 shot. Thinking on the Hatsan Hercules modified. still less power than the Texan. Will consider having one powerful shot then loading by hand though. But may go Hercules.

[@budtoker4770]

I bet if you increase the valve opening spring you could shoot higher pressures @ greater velocity!! Too much pressure retards the valve from completely opening!!

[@jimmylaplante1700]

The expansion bubble is Dieseling, see the burn.

[@pwengineering9070]

You know, someone in the government are going to see all these advances in airgun technology are will want to regulate them. Most likely they will place air propelled ammo guns in with gun powder propelled ammo guns. They will likely regulate by FPS or by pressures? I can see it coming.

[@yaddahaysmarmalite4059]

If there is any such regulations to come along, it'll probably be from the powder burning gun manufacturers because they will want to reduce the competition in the market from airguns. If you can't play fairly in the free market, then use the gov't to knock out the competition then blame it on the liberals so no one wises up on who really lobbied for airgun regulations. Just watch. They've been bamboozling you this whole time getting you to vote against your interests.

[@zoranzuvela9856]

Great job!!!

[@justinrobinson692]

"Its four inches about the size of my I won't say" I fucking dieddddd

[@raymondj8768]

1776 some sounds familiar about that doesent it ????/

[@CHOPERUS23]

Seems you're just balancing the helium to your valve pressure. Try increasing the valve pressure to increase velocity at higher pressures.

[@Masteradamant]

I was wrong this has multiple shots; amazing gun. If the Zeus .72 cal can get multiple shots, this should get multiple shots also.

[@sanleonster]

Does the Helium really make a difference? what are the numbers with just shooting straight air in that gun.... My AireTex compressor fills my carbon fiber tank from 2900 to 4500 in about 6 minutes... I sure couldn't wait 6 hours on a shoebox, I do too much shooting for that.. great video as always Mr. Hollowpoint, keep them coming...

[@SwampOperator]

Roughly a 30% increase In overall performance. Fps, fpe, ect.

[@Dr_Wrong]

Oh, THIS is Mr hollowpoint..

[@silenttitan7636]

Is he already taking orders and does he have a price range I definitely want one this puts the dragon claw to shame a thing of absolute Beauty thank you Lois and Clark for pioneering the air gun as well as the United States

[@yaddahaysmarmalite4059]

Lewis and Clark did not pioneer the airgun. Their airgun was imported.

[@shanepowell5115]

AWESOME

[@thequigley72]

Helium has smaller molecules so more escape past the valve and adds a 1/3 more speed.

[@williamscott2461]

It’s intriguing, but with the noise, hoses, tank, ect, a cartridge gun is much easier. The expansion of the slug is impressive.

[@ahtauwylye1340]

A 20mm cartridge gun? Youd need a lahti l39

[@dinadaughtry8993]

You would also need a good doctor to put all the broken bones and torn muscle tissue, cartilage back together

[@frankcardinelljr4433]

Gotta correct and conform the castings of the bullet

[@nicholasplesko533]

Does the slug even expand? It's not traveling very fast.

[@Mrhollowpoint1]

Look at the ballistic gell, opens up very well, but yes more speed is desired

[@DDIAZ-we4dz]

get one of those ballistic gel dummies that cold steel uses in their channel to test knives on. the ones that have a skull and ribs and organs and blood. itll be a fun site to see what that thing can do.

[@Nazareth434]

so these are gonna run about $150-$200, right? I'll take 3 please

The reasoning of why helilium is more powerful is incorrect and actually the opposite of what’s taking palace. It’s been 7years so I’m sure you’ve figured it out by now.

[@BigFun4Life]

Mr Hollowpoint I’m a Michigander and I’m trying to find out if Brent is still manufacturing big bores.I messaged them but got no response?

[@dylanp.5161]

Awesome!!! For a 20mm air gun, how big is the connecting piece that connects the barrel to the air chamber. On small caliber air guns the hole that lets the high pressure air (or in your case helium) into the barrel is tiny. I would imagine a large caliber gun needs a much larger hole/connecting piece. What size do you recommend?

[@hectorjovel953]

que tipo de rifle es ?

[@Mrhollowpoint1]

El Rifle es de extremo grande del alesaje Carabinas de aire comprimido, el sitio web es en el video y el calibre es un 20 milímetros o calibre 82. Espero que la traducción está trabajando.

[@draganbalzic4493]

Hopefully the 834Fps keep the slug just under its Mcr and out of the transonic zone for stability’s sake. What’s the barrel’s twist rate?

[@SwampOperator]

He'd have to get well over a 1000 fps to go sonic. Depending on the humidity 843 is well below Transonic regardless of the humidity

[@HenriqueSilva-ow6qy]
