Very nice gun. I would recommend lowering the C:B ratio a bit. This is not to gain greater distance through greater efficiency; however, greater efficiency will lead to less noise, which is less likely to scare the dog when you fire the tennis ball. Though, I have never fired a combustion before, so I do not know whether this will be an issue or not. Great build.

yea i know the ratio is way off but i want to keep the cannon small and the gun has already been cut down once. i just figure i will mess with the propane mix until the desired power is reached (ie a greater than 4% ratio)
