What’s 560 MPH in FPS, for us mathematically challenged individuals?
The Gun Control Act defines "firearm" as:
A) any weapon (including a starter gun) which will or is designed to or may readily be converted to expel a projectile by the action of an explosive; (B) the frame or receiver of any such weapon; (C) any firearm muffler or firearm silencer; or (D) any destructive device. Such term does not include an antique firearm.
It doesn't use an explosive propellant -- it is not a firearm, and the ATF has no authority to regulate it.
Given his Imgur username, I'm sure he already was.
~ 820 fps. Faster than a .22, much slower than most anything else. When it gets over 3000 fps, color me interested. Would like to know approximate weight of projectile also; if they are heavy enough then it might be interesting sooner.
about 800 fps, but what difference does it make for a mathematically challenged person ;)
Actually, slower than a .22, even subsonic (1025 fps).
So does this violate any laws? Gun manufacturing laws/permits? Does it meet the definition of a gun?
Whats 560 MPH in FPS, 821.3 FPS, same as .45 ACP.
Needs more calibrations.
I think it might qualify as D) a destructive device.
What I want to know, is how does non ferrous projectiles, such as aluminum, work.
in Kalifornia, all of the above are probably true
I like the one video I saw a few weeks ago where this guy made a homemade flamethrower that could shoot ignited fuel 50 feet which to me at least, looked like it could burn 100 people alive in a few seconds which I can guess would greatly please liberals as obviously they would prefer a psycho use that instead of a gun.
Looks like something outta Ghostbusters.
A more useful measurement for a weapon is ft/second. In this case, that would be 821 ft/sec. Not really very fast. Good pellet rifles regularly exceed 1000 ft/sec. Of course, this is a first iteration. Subsequent ones should be able to improve on this.
At least someone could yell “Fire!” if they used that in a theater...
How heavy was the projectile? An arrow traveling at 800 fps is a formidable projectile, for instance. Mass matters.
Aside - google has a little known feature that you can put such questions in the search bar.
560 mph = ? ft/s
