My theory is that it is a miniature automag style mechanical spool valve, and possibly unregulated, therefor the only way to change the velocity is to change the size of the dump chamber, by putting something in it to fill up space. It might be regulated, similar to tpx or t8, in which case velocity adjustment should not be an issue.
If it isn’t field legal without some modification, I don’t see that as a big issue, neither was my Zeus.

Another cool possibility is if you could add an ammo tube thing like the dvr revolvers.

If however Mar just quick keyed what I think he meant, 1/3 an apothecary dram, for he is a genius and did that perfectly off the top of his head. However, ballistic calculators seldom go under 500 fps. At 361 fps, ~150 yards at a 45 launch is a fair guess so right around 3/4 a furlong.

haha thanks! My father and bother are both mathematicians... it skipped me... so will the 7.5 joule marker shoot 50 cal balls at close to legal speeds?

No not according to their website.

umarex.com

7.5 Joules is 110 meters per second = 360 feet per second.

11 Joules is 134 meters per second = 439 Feet per second. But that is in 50cal, Im guessing 50 cal is still a 300 FPS or under.

Well at least bringing the velocity down would be easier than bringing it up I'd imagine.

I’m sure. Especially with all the talented guys on here.

I’m smelling a custom run of parts to legalize these puppies.

When I started doing shells for my revolvers the apparent thing i noticed was the hole size in the cartridge controlled the velocity of my paint.

Perhaps this opens the possibility of small, tippmann-style aperature velocity adjusters- a small grub screw installed behind each projectile space in the cylinder, perpendicular to barrel.

Anyone care to translate? My limited knowledge of the language isn’t getting me anywhere.

Bigger than I thought it would be. If that doesn't come in .68 given it's size, I would be surprised.
