Well has anyone seen those 12gauge "flame througher"(I think they call them "dragons breath") round that shoot out a 50-100' long stream of burning material. Well I have a old .36cal BP colt replica and though if I took the barrel off and just had a small snub of a barrel and loaded in this"flame througher"
comp it would make a cool devise/weapon. So does anybody know what the hell is in those "Dragons Breath" flame througher cartridges?

Fl4PP4W0k,
Who the fuck are you...!? Show some Respect...Slut!
It would be a type of Fine powder. You Options would be Flamable Metal(ie. Al,Mg) or a Hydrocarbon(ie.Napthalene). Being able to produce this effect for a distance of 50' or more could be difficult.
You could use a projectile with an open end(most likely to the back), The Powder would be pressed lightly into the projectlie.
Another option is to Press the powder into a grain. The Air Ruhing Past it a it ired would leave a dust trail of your powder.
Just my thoughts...

Sheesh, its called a _joke_ :rolleyes:
Take ya pills man :p
Aaaanyway...
<a href="http://cobraysbad.freeyellow.com/DRAGONSBREATHorder.html" target="_blank">http://cobraysbad.freeyellow.com/DRAGONSBREATHorder.html</a> are what you're talking about? Yes?
I am guessing that there may be a thermite like composition - possibly pressed hard, or bound with plaster, which is ignited by a small amount of BP delay + Mg dust in the center.. so it burns outwards(after leaving the barrel!).
This would be housed in a sabot - to protect the bore of the gun.
I am not sure of the best composition, though standard thermite sounds promising. Fe<sub>2</sub>O<sub>3</sub> + Al would make sense, as this composition is cheap, simple and effective. Probably would not be able to be extinguished by the passing air?
Having a solid grain, as mentioned by Blak, and burning from the rear forwards, could also be an option. This would probably make more of a trail of flame... than a growing fireball (central ignition).

Blah, blah, blah...fucked myself off!
:mad:
I leave it to you to remove your disrespectful post. Saying "It's a joke" doesn't cut it. And, judging from your other post at the former Forum site, you may have been drunk at the time. So you'll be given this chance to correct yourself, though drunkeness will be NO excuse for future stupidity.
Also, it's stupid to NOT search for a patent first. No sense in recreating the wheel, now is there? :rolleyes:

I wasn't drunk... smoked a bit of resin with my (almost finished!) hookah though.
Ill edit it, though I cant really see how 'twas disrespectful - was just meant to be a joke. Oh well :(

Obviously fl4pp4w0ks link is a real "dragon's breath", but I swear I have read about something along the same lines which uses flash paper (nitrated paper). I suppose the "fireball" of some flash paper would be rather minimal, but simply as an effect or even a long range firelighting device, it would be very cheap and simple...
I'd much prefer to make some flash paper and have small yet cheap fireballs, than pay US$20 for 3 of them!

Flash paper would be too fast burning for a 'Dragons Breath' type device... (The "Flash" part of the name hints towards that :p )
For a "long range firelighting device" I would think a small cylinder of pressed \ bound Thermite would do the trick. Though depends what the devices intentions are...
If you just want to light... say... a gas ballon or something :confused: from a distance, then I guess a flash paper fireball may be enough.
If ya want stuff to BURN then an incendiary like thermite or phosphorous comp would do the trick. Even KNO3\Sucrose could be used effectively.
BTW, I have seen (a while back) a theatrical prop which shot out small fireballs. You flicked a lever on the top - it was a staff - and a fireball came out of a figures head. Neato :D
Is that what your talkin about?

You'd need a good priming composition, and probably several intermediate prime layers to get a grain of thermite to ignite from a gun propellant discharge.
Thermite is hard to ignite as a lose powder, but pressed into a grain it's going to be hard to locally overheat a spot and get it to ignition temperature.

This looks like the well known firewoks. The shell may have 1/4 black powder and other part full of small "stars" made by pressed slow burning flash...

Perhaps the name 'dragon's breath' from the device might be borrowed from the common name of lycopodium powder, 'dragon's breath'. Perhaps the round is just loaded with pressed lycopodium powder with a small layer of gunpowder near the primer to enhance ignition. The primer shatters the pressed lycopodium and the powder layer aids in ignition. It may be worth a look for the home loader's.

I think there's a patent for this, but I don't remember the number.
IIRC, the charge is misch metal compressed under great pressure with a binder to form a slug. As the slug is fired, the flaming propellant gases heat the misch metal to red hot. Once it exits the barrel, it instantly reacts with oxygen in the air to ignite in white hot sparks.
(Misch metal is a generic term for a combination of rare earth elements used in lighter flints)

I've tried looking for a patent under "dragons breath" and compressed metal flame thrower. But came up with nothing, so maybe they called it something else. Any idea what they might of called it in the patent? When I'm at the gunshow at the end of the week I'll pick a couple up. But heres what I think, I think what it is a fixed block of fuel metal and some kind of propellent, made into a rocket like pellet(like a pyrodex pellet) and as it burns the metal fuel it expelled creating the stream of fire.

It's not going to be patented as "Dragons Breath", but rather something like "Incendiary compound comprised of rare earth metal complexes and alkaline nitrates" or some other techno-babble term.

Well I tried "dragons breath"/"Fireball" under the trademark search, then I tried rare earth metal incendiary flame thrower/shell, metal incendairy shotshell/bullet, under patent but still nothing. I think I might just have to shell out $20 for three of them at the gun show coming up. Though the package they always but them in is rather small and theres alot of people there for a distraction, you never know I might be able to get some for free. <img border="0" title="" alt="[Wink]" src="wink.gif" />
