What alot of people don't know is that the folks who made paint ball guns used Mr. Casselmans design and made paintball guns using a computer chip to control the firing rate. Thank you to Mr Casselman and his creation and the sharer of this video and link to the build instructions

@SKUMMASBAGGUS Be sure! He´ll be remembered by me and by all his friends every single day of our lives! His memory´ll be honored in all our toughs about guns, survival, and the perenial fight for freedom! I´m sure Luty´s Soul´ll help us in our struggle against tyrants! Be well, my dear. Abe.

That is, alt. it is only "air", the pressures under it is compressed on the bottle and is freed inside the barrell is as high as any handgun-class conventional cartridge, that is, something deserving the utmost respect!

Yes, I´ll build one with the same caracteristics but in .22 caliber due to Brazilian Gun Laws. I hope that in such caliber it can reach a MV of at least 1100 FPS.

the one i saw was designed to fire .30 caliber buckshot pellets

Glad to be of help to like-minded minds! Cheers!!! Abe.

thank you for posting the link for the free builders plans,i have my copy and my bother is a machinist.
Yes in USA, w/o any license; yes in UK or all Europe with some license (due to muzzle energy); yes even here in Brazil, with a lot of red-tape. Now we´re working on a perfect replica of the Girandoni, and our small workshop can not do two guns at the same time (we´re not professional gunsmiths). Sorry. But I can help you with it, for free. Anyway, look at my friend´s Phil Luty site The Home Gunsmith (com) - he may help you much better than me. Best wishes! Abe.

genius. pure genius.

@Stijning Yes, my good friend Phil Luty is dead. May God bless his soul.

A .50 Browning heavy machinegun cartridge (12.7x99mm) have up to 75.000 PSI at the peek of the pressure, but it lasts only a fraction of a second, we can say that the relative constant pressure inside such a barrell of, say, 42", it´ll be something like 15.000 PSI;
this is the great ness of jeff caselman xposed to the world i love great man great inventor check his air shotgun out guys we just put this vid out
...with soft lead slugs, it´ll mushroom and not penetrate a hard target, but it´ll transmit much more shock to the target; with expansive projectiles (L-HP, SJHP, JHP, JSP, SJSP, STHP, Glaser, MagSafe, Black-Talon, Explosive slugs, etc.) you´ll get +shock and -penetration.
hence, a 3.300 PSI constant pressure inside a 20"-30" barrell is roughly equal to the pressures developed inside a 7"-11" conventional submachinegun barrell in such conventional submachinegun calibers ranging from .32 ACP (CZ Skorpion), .380 ACP (MAC-11), 9mm Luger (MAC-10, MAC-11/9, UZI, H&K MP5, etc.), .40 S&W (Taurus MT-40), .30 Luger (Bergmann), .30 Mauser/7.62mm Tokarev (PPSh), .45 ACP (Thompson, MAC-10, M-3, etc.).
The pressure the fluid (in this case, air) is compresed at. To you get a rough idea about what such pressures means:

É meu amigo, com este maravilhoso estatuto do desarmamento, ficamos confinados ao "underground" e o que ainda nos resta é construir armas assim... To pensando em construir uma .32 com 4000 PSI + silenciador, excelente opção para defesa patrimonial... abs

...and, yes, with such hard Armor-Piercing loads, it can puncture steel plates, armored plates, body-armor, i.e., everything in Level III-A and lesser ballistic levels protection; with conventional FMJ "Hardball" projectiles, it may or may not penetrate hard targets, as any .45 ACP carbine/smg can or can not; ...

could use an SCBA bottle at 4500psi for duration on a 1000 psi HP renforcced braided line

It shots just like a conventional (firearm) Thompson SMG in .45 ACP Caliber (alt. on the clips the Caselman is in .30 Caliber, with the same power & ballistics as a .32 ACP SMG with long Bbl.) - that is, if you use AP rounds in the caliber (.451 in the case of the .45 Caliber), you´ll have the same power (and rounds per minute rate) of a conventional Tommy Gun (+or-900 fps, +or-700 rpm), ...
Hi. In any caliber I´ve saw it shooting (.308 with .32 ACP slugs, .355 with 9mm Luger slugs, .451 with .45 ACP slugs) it shots at the same velocity: under 3300 psi of air-pressure it has a MV of 790 fps and 311 FPE at the muzzle. You can estimate it´s velocity at any distance by comparing a Tommy Gun SMG in .45 ACP - it seems to be very close in the two guns. You get similar velocity and energy from the Caselman and a (conventional firearm) Thompson in .45 ACP. Not bad for an air-gun, uh?
@Stijning No. Here in Brazil it is a crime punished with 4+ years of prison to just build any firearm without a license.
100% legal in USA. Any airgun, in any caliber, is legal in USA.
I think it´ll be not very hard to build a loading tool, something made from PVC pipe, like the one´s used to speedload a pump-shotgun, but loading this gun from the top (of the magazine). It´s still something you can improoved much.
@jrrabrahao Thats it... here in America its like at least 10 years.
ASAP!

Hi. It´s not me, it´s the inventor, Mr. Jeff Caselman, firing his brainchild. Regards.
Thank you, but I´m not the gun´s inventor. Best regards. Abe.
@dilwashi369 agreed, nice capacity also.
Hey, does anyone have the files or a link for a different host? The original link is dead as a doornail... :(
@jrrabrahao Hey, for some reason I can't download the zip file in your comments. Is there any chance you would be able to re-host it? This is a very interesting air gun!
1
Holy Shit Nice
@jrrabrahao you guys are great at this i may make one
@SpunkHunter4Life What counter? I didn´t put anything that isn´t there originally from the VHS tape... Please advise.
Well, this gun can use pure steel, tungsteen, copper, brass, or any mettalic alloy bullets out there...

I cant download the folder/file,it says its corrupt,can you send me the file/drawings please?or give me a link that works,thanks Stew.
can you get air gun kits for this cracking airgun
Boa noite. Gostaria de saber se conseguiy concluir a construção do modelo. Obrigado.
is this yours? Did you make this? Or is this vid from somewhere/someone else?
does anyone know how far away he was standing when he shot at the 2 x 4

Is that legal to build? If yes, how much would you charge to make me one?
