that is pretty funny but what about Wisconsin in the U.S.

you mean 7' barrel and 4' chamber?


then where can I buy the pipe what kind of hardware store

I guess I will go with 7' barrel and 3' chamber with diameters of 2.5" for spuds and tennis balls and 3" for the chamber only question is where do I get the pvc, like what store? will they let you buy if they know it is for a cannon?

probably 2.5" barrel and 3" chamber I dont know what fuel but what I am asking is what should I use for C:B

Hi I have not built a cannon and am going to start I am going for a 10' cannon and want to know whats a better & efficiant ratio

7' Barrel and 3' Chamber

6' Barrel and 4' Chamber


any others?
