Powerfull Marble Sniper , advices needed

[Angel-FR]

Hello ,
Im just trying to make a good marble sniper and i want it to be the best possible... i plan to make it with a cannon of 1,5 cm of diameter with a height of 1 M but if i want a ratio of ~0.8:1 i need the chamber to be something like 2 cm of radius and around 10 cm of height , that's very little and i wont manage to get the right amount of fuel in it (hairspray) or i would need to make a metered propane system and i dont want to make one for the moment... so , how could i do a very powerfull marble cannon ? i want to shot over 300 yards with it !


thanks for your help

If i were you i would make it a pneumatic. But thats just me.

A chamber of 2 cm radius? That definately wont get it 300 yards. But im with bluetooth on this one, if you want it to look like a sniper and be effective you kind of have to make it pneumatic.

300yards with a marble and a combustion that size defiently go with a pneumatic as it would be smaller and easier.
