Chamber to Barrel Ratio for Propane cannons

[MisterSteve124]

I read somewher that if you want to build a propane cannone you should use .8:1 C:B Ratio. I was just wondering if this is true? If not then I'll just stick with 1.5:1

[Tater Salad]

yes this is true. Some people might say that .6:1 is better but thats for efficiency. The better the ratio (.8:1, 1:1) the louder it becomes and the more energy is wasted. 1.5:1 is best for aerosol fuels.

ok anyone else? sorry but I don't really trust someone with only 1 post.
