I don't see how a CLGG would be illegal if somebody had the facilities to make one worthwhile...

So can a pneumatic

Are you two mental? The longest shot from ANY homemade cannon was pneumatic, but it was only 4800 feet, and it was in Punkin chunkin. And Warhead 6 miles? NO! 6 miles is over 31,000 feet! WTF ARE YOU TALKING ABOUT? lol AND Gun freak, He wants raw power, please don't dilute him with your backwards, one-sided pneumatic beliefs! (even though I prefer pneumatic also.. lol) Not flaming you guys, just stating facts.

That's the world record for shooting a PUMPKIN, in competition, with a relatively low air pressure and a very slow valve. Even that cannon is capable of easily several times that range using something denser and more aerodynamic than a pumpkin. They're throttling back their power a LOT just to keep the pumpkin from exploding upon exit from the barrel.

There was supposedly an experimental warship in the late 1800s that used air compressed by a steam engine to fire shells several miles. I can't remember whether it was British or American, but the name was something like Volcanic.

Think about it, an explosive driven cannon? I think that the state would have a problem with that, unless you were licensed to do that sort of stuff.

What's the difference between that and a hybrid except the gases? Combustions and hybrids are 'explosive' driven cannons.


Edit: I was talking about CLGGs not LGGs as I read that from Mark's post instead of reading Warhead's.

A CLGG and LGG are two different beasts...

Have fun constructing a LGG with elevation control though lol - constructing one on perfectly flat ground is hard enough!

I'd have to put my money on EM accelerators having the most potential for "long distance"... no sound speed limitations.

EM accelerators have their own troubles. Even induction coil guns will run into troubles with melting their projectiles as launch speeds climb. Single use, multi-stage LGGs can likely be made to exceed 20km/s, but doing so would be so outlandishly expensive that I doubt it would ever be attempted.

Also, warhead... You do realize that hunting rifles are "explosive driven cannons", right? And that they're practically unregulated in the US so long as they're under 0.5" bore? There have been HE driven LGG designs, but apart from accelerating flyer plates or gas jets, they don't see any use, and are considerably less practical than the standard LE-powered type.

Conventional 2-stage LGGs use essentially the same propellants and would be quite expensive to construct in bores over 0.5", so I can't see where this argument is coming from. As to all other countries - it's all illegal, and your typical garden-variety judge or prosecutor couldn't tell an LGG from a spray'n'pray if his life depended on it.

DYI, by explosive I meant C4. Last I checked you can't use that legally any where, except maybe Somalia.

Almost got the name right, it was a specific volcano

Warhead, as far as I know, LGGs don't use detonating materials to drive the piston, they just use conventional smokeless powder.

However, Voitenko Compressors do use high explosives to drive the pusher plate.

Thank you, JSR! I spent hours searching for that stupid ship that night and couldn't get a single return!

Warhead... Did you even read past the first sentence of my response?

To paraphrase it to better suit your attention span: What the hell would C4 be doing in an LGG? They use essentially the same propellants as conventional firearms.

Sigh...

Read the third post of your link warhead.

Yeah, uses PLASTIC explosives.... Or C4. This argument is getting no where, I'm out.
