Dodo 225 Yes it is big, and the reason is the Madsen barrel, I didnt want to cut it any shorter. And the weight is a good thing, helps to manage recoil.
J K Nice, just be sure to make the proper structural calculations and material selections. High pressure air will kill you if you mess up on material properties or calculations.
@@MJPilote absolutely! this is not something I’m going to tackle solo. The company I work for is a full blown fabrication shop. We do a lot of pressure vessels among other things. The horrible part is everyone wanted to scale up a semi auto airgun I have 🤦♂️ though the thought is fun I’ll stick to a single shot for now. “If” we actually do a semi auto I’ll let you know if it actually works👍
@@JK-dn4pu As you understand this field, I have 2 ideas for a totally off grid pcp hybrid . Have you seen how much extra fps you get when you diesel/ Vaseline a projectile? Why has no one built a platform to take advantage of that? Just need a space between the valve and projectile where a measured dose can be applied automatically with each action? If Navy divers have 10,000psi carbon tanks for rebreathers, how hard is it to make an air can for PCPs of 6000psi? My ultimate bulpup rifle would have a vertical stick mag eg. 25 x .45 cal, have 30-40 regulated shots 1000fps and be semi auto, and can handle vaseline behind the Slug, with carbon Fb light weight barrel 50cm , light weight & compact. for when TSHTF
Incredible machining. I’m assuming you’re Finnish by your accent? Are there no legal restrictions on building air rifles this large? Just curious! Love this build a lot
Steel&Cider - This was made before the EU gun sanctions made life difficult. It is tied to my firearms license. Making one now will require a personal manufacturing license for a gun, but you need to convince the authorities of your need for the gun to get the permit. And yes Finnish rally English.
MJPilote Thanks for answering my question, and I’m sorry you can’t build any more of these because of the restrictions. You are right in that Finns rally anglophones, I think you guys have something special going on that interests us lol
gsxtr1 Well if you have ever watched WRC rally or F1 and listened how the Finnish rally and formula drivers speak, you'll know what it is. That's rally English aka bad English with Finnish accents
@@MJPilote I know this is a bit ot. But i love the build. Live in DK atm, born in Tampere. And i do know how to Google the Gun. Is there anyway to build and shoot it, in club setting 🤔 Stay safe 😷👋🏻
I really love this. Really cool. Glad I subscribed and got to see this. Nice machining and good ideas for the locking lugs. This video was very inspiring to me, and now I have something to dream about!
Congratulations! Awesome build man! I am happy to see the most powerful one being a homemade one :D This also makes me more motivated to somehow build a decent one. Not so big and powerful as this one, but a decent one. Curious to see what can I do without special tools or materials. Cheers!
Thanks, and a word of warning. Please be careful with high pressure air. Choose your materials carefully and do your math. You need a proper safety margin to yield on everything that sees pressure. 2.5-3:1 safety to yield. So your design should hold 2.5 times the working pressure without yielding. Then you know it's safe. And hydro test everything to at least double the working pressure. If it yields then start over with different materials.
If you made this you need to start your own company. Whoever made this is one badass mf. I wish I could make something half as awesome. I'm just absolutely blown away. I'd love to see the maker make a pistol
Nice work M! If you ever get over to the states we will go deer hunting, hog or Moose(?). There isn't anything bigger except at the zoo and that is frowned upon.
@MJPilote Hi wow what a cannon, Looks engineered very nicely ! Does this have anything to do with the AEA Fury, which is on their site but no one seems to own or shoot?
@@MJPilote you were getting 1470fps? That is very impressive for a air rifle. Too bad it is so expensive. My 357 Magnum rifle is cheaper, faster, and hits way harder, but way louder
@@FUW-guy Your "My 357 Magnum rifle is cheaper, faster, and hits way harder" bla bla bla does not hit way harder. This gentlemans Air gun does 3108 fpe. Your 357 has a higher fps muzzle velocity, but not fpe foot pounds of energy. I checked the ballistics for a 357 magnum rifle not even close to what this Air Rifle does for fpe. A gun that has more foot pounds of energy "fpe" means it is going to do more damage. You know like hit harder.
Nice Air Rifle! mrhollowpoint makes 20mm slugs in 640 grain, 960 grain, 1150 grain, 1588 grain, and 1750 grain not as heavy as the 185 grams= 2854 grains you are using. I thought the 1750 grain slug mrhollowpoint makes was heavy but 2854 grain wow.
May I recommend making a magazine for the gun. I am also thinking you can make some brass or steel cartridges that can hold compressed air or some other gas and then the bullet itself.
Number 1 question I'm sure any Air Gunner would ask is, when does it go into production so that I may get in on the fun...? I would love to take this beast on a bear hunting expedition..
Sorry for the late reply, have not gotten any notifications for what ever reason. I cant do a production run as I dont have a gunsmiths license. was thinking about selling the cad files but that remains to be seen.
SnowblindOtter Thank you for the compliment! And unfortunately I can't make one for sale, for that I would need to be a certified gunsmith. And the price would be very high, the barrel alone is a very difficult to find as a civilian.
@@MJPilote Well, if you _were_ to sell it, considering the cost of materials and the labor you put into it, how much do you think you'd put it for? I'm mostly just curious to know how much it cost you to make it, because you clearly put a lot of effort into it.
SnowblindOtter Well I think I would not even start to think about selling one for less than 5k€ but realistically considering the work involved in development I would need to put the price around 10k for a unique one of a kind build.
jafinch78 valve is basically a hammer actuated poppet valve that has a balancing piston to reduce hammer mass. K mauser trigger releases the spring powered hammer. Very simple design. There is some video on my channel how the balancing valve functions on a smaller gun.
@@MJPilote OK, I'll take a look. Thanks for the reply and detail. Interesting studying the pneumatics of these designs now that I have a pressure washer for some testing purposes of other designs.
Little House of Horrors Thanks, a lot of engineering and testing went in to making the gun. I can't give the blueprints for possible legal issues that could arise for misuse or possible scenarios that come from use of wrong or unsuited materials.
Unfortunately I can't. EU gun laws and local gun laws prohibit that. Need to he certified gunsmith to manufacture big bore airguns in Finland, and that takes 4 years of studying. So no mass production for this one.
WilliamTheGunNut All airguns larger than .25 or 6.35mm requires either a license or if the owner has firearms license no other licenses are needed. Only mandatory registration for big bore air guns.
@@williamthegunnut3839 Yes, we have no power limits on small bore airguns. The lucky shot .223 featured on another video is license free and has around 200J of muzzle energy.
dewayne martin it's one of a kind and not for sale. Local laws don't allow me to make anything over .25 caliber and sell it. Everything bigger and its tied to my firearms license and I need a private building license to make them. Need to be certified gunsmith to make anything bigger for sale.
