diesel fuel or kerosene is not nearly as volitile as regular gasoline. If volitility is a concern, then just use one of these lowere grades of gasoline. You will actually get a stronger explosion. Also, I believe that gunpowder is much more powerful than gas or diesel, but with .22 cal pellets, you don't need anything more powerful to propell them well beyond a supersonic speed, given the right gun.
I have allways wondered why no one has ever invented a petrol based firearm. It was not until I became interested in spring guns that I even considered revisiting this issue. But in small calibers, like .22 pellets and using only a tiny amount in soaked cotton balls, about the size of a small ball bearing, it becomes a real practical method of making a .22 cal., or even a .25 cal. rifle or pistol. The amunition cannot ever be confiscated or banned, because fuel and lead are far too common to take out of the public's hands. It cannot be regulated as a firearm, because it would be designed to propell pellets using air - what people do with them after they buy them is their own business.
I would design it with a heavier barrel, i.e. one of handling a .22 long cartridge; with heavier piston seals; and with a locking block, so that the piston and spring would not be damaged. This kind of gun fly's under the "firearm" radar, but is capable of handling an explosive propellant, if the user decides to take this risk.
Just food for thougt! You have to admit, that it's not difficult to create such a gun that opperates fairly safely. Judging form the numerous posts here about "dieseling" I'm not the only one currious about this.
