@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!
@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.
Do you have the entire video that Jeff Caselman sold or do you just have the clips that you have posted? If you do have the entire video how long does it run? Thanks for sharing some hard to find info.
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.
It will certainly be a difficult job, unless you're experienced. Especially the bolt mechanism, as it has to move forward and back and release just the right amount of air and all that. But 1100 fps is definitely achievable with the right design. According to his original plan, he estimated the velocity as 1000 fps, but 800 fps is substantially lower.
The whole calculation is dubios, imho, but I'm sure the gun works. It does show that his valve system isn't the optimal, however.
Cont. a longer barrel would make it easier to achieve the speed, but I would probably go with a super heavy pellet instead, for example the new H&N rabbit magnum 2, or Eun Jin pellets, or even rimfire bullets. and settle with a lower speed. 900 fps would be ideal, considering the ballistics.
I'm not sure if the H&N bullet could handle the magazine mechanism and loading, though, perhaps lead pellets won't work.
With 3000 psi and cal .22, over 30 fpe is quite possible with heavy bullets.
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.
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.
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), ...
...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; ...
...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.
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.
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!
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;

In an air gun? Under these levels of pressures, maybe 15 feet or so.
jrrabrahao 4 years ago
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!
jrrabrahao 4 years ago
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.).
jrrabrahao 4 years ago
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;

The pressure the fluid (in this case, air) is compresed at. To you get a rough idea about what such pressures means:
