: Something like that could lead to paintball cannons that work using a shell much like real cannons. I can't picture it being cheap to operate though and the development costs would be pretty high too. I am concerned about a shell concept. The one thing that is not accounted for in this model is temperature. If the temperature increases, then a gas under pressure will increase the pressure. This requires an expansion chamber, like you can purchase for your marker. If you could keep you gun at constant temperature or have a pressure regulator on every shell, it would also work better. : The thing I'd be concerned about using some sort of chemical reaction based system would be it's consistency. Although I would think that most contaminents would decrease such a systems reaction and lower the velocity, there's a chance the opposite could occur. The idea is not for novice chemists to do this, but to get the same component used in airbags from the manufacture. These will have tight engineering tolerances, which will allow the user to know exactly how much gas will be produced with some minimal variability (after all, if an airbag were to overinflate, there would be a big problem) : I guess it would depend on who was building it. Someone like Ford or Chevy whipping out hundreds of thousands of air bag cartridges would have much better quality control than say one of us making paintball cannon cartridges in the basement. I just want to know who supplies the inflation modules to Ford or Chevy and if they will sell them to me.
