| Oh…crap, sorry I didn’t know you lived in Australia. I see what you mean it would be a waste of money… |

mmmmm I know, I love living in Australia but our gun laws suck.
I wonder if anyone on this forum would be willing to build a gun based on this cartrige idea? Not even anything too complex, just a single shot gun with a breech for a cartrige. You would be able to reload very quickly if you prepared several cartriges. |

| Someday I’ll be making one, just it’ll be a few years (were planning on moving and I can’t make anything big until we do) but mine will be a 200cal recoil operated hybrid automatic howitzer. Used to deliver anti-personnel rounds (for paintball) range doesn’t mater as it will be a fixed weapon mounted at a bunker complex, or mounted as the main armament on a tank. |

| A hybrid paintball cannon would win in a competition even if you forgot to drop the paintballs in. It would be so damn loud no-one would have the guts to go anywhere near it lol |

I know I’m planning on using Pod Rockets (Google it) and a 200cal barrel. (just so everybody knows, that means two inch) range and accuracy aren’t an issue, so long as it shoots. Think about it, a guy walks up to the bunker gets ready to fire and then all of a sudden… BOOM BOOM BOOM BOOM BOOM. I grantee that guy’s a little moist now...
Any who, I’m planning on having a five round magazine, recoil operation, and a short barrel so the BOOM is louder.
Psychological warfare is fun… |

So the hybrid part of it is just to make it louder, and the short barrel both makes it louder and makes sure you don't kill the guy your shooting at.
What happens if the shock forom the gun sets off the grenade??
Also, are you going to attach the pin to the cartrige so that it is armed as it fires?? |

The hybrid part is also to fire it, the case would be pressurized to below the bursting pressure of the burst disk, the combustion from the propane would burst the burst disk and give it enough recoil to cycle, I hope.
Attaching the pin to the case is a good idea, I can’t believe I didn’t think of that! There is so many ifs it’s not funny: IF there is enough recoil to cycle, IF the paint grenade doesn’t go off in the barrel…ok so there is two ifs, but there big Ifs…
A thought accrued to me a couple of days a go. If I use a gas tube and bleed off a little bit of the firing gasses to unlock the bolt it would give it a little more power.
My advise to anybody who wants to make an automatic spud gun: do some research on how the real machine guns work, especially the pree-WWII models |

| Yeah I know that the hybrid part fires it as well. I haven't done much research into machine guns yet, but from what your talking about it sounds like you would need lots of recoil for it to work. So, why not put the grenade in the case, but before you put alfoil over the front to keep the ammo in, fill it with water. That would give you more recoil than the grenade alone. You could also try cartriges filled with regular paintballs as a close range shotgun for wiping out heaps of people at once. |

The scattergun idea sounds good, once again I can’t believe I didn’t think of that…
Yah it’ll take some recoil, but not a hole lot, have you ever fired a combustion or a large bore burst disk cannon? If so how much recoil do they have on a scale of zero to ten, with zero being none and ten being 12GA? The main problem is there has to be a return spring, that spring has to be powerful enough to close the bolt but light enough that the recoil can open the bolt…funny how this topic started off being about a “no burst disk hybrid” and now were talking about an automatic cannon… also how come nobody else has anything to say? Are we the only ones smart enough understand it all? (Just kidding) |

Or are we the only ones dumb enough to think this will work lol.
Yeah, I wondered why no one else has posted but anyway, back on topic.
I don't know how much recoil a large cannon makes because I have only fired my ball valve gun, but my friend fired it with a barrel full of water and said it kicks more than his .22 rifle. I couldn't even rate it on the kick compared to a 12 guage as I haven't fired a real gun yet 
Oh well, when Im 18 I'll join a gun club and then I can get a gun licence 
How far does the recoil have to push the spring?? If its only a short distance then I think it will work, and even if it is a long way so long as the parts are made well and slide easily then it should work. I suppose the distance it has to go would be related to the size of the cartrige. If it didn't have enough recoil you could always run it at a higher mix. |

| Try about two feet… because that’s how long the case would half to be for it to be useful…although if the thing’s fired with the muzzle in the air at a 30-45 degree angle then it would be a lot easer… |

Here's my idea for a no Burst disk hybrid.
It uses 20 psi and acetylene. All parts must be sch 80 metal or higher. |

| So your idea works because acetylene is unstable at high pressures?? I imagine that such a gun would have to be metal, I doubt pvc would handle the explosion. |
