So I decided to build a mini cannon to learn the basics of being a cannoneer and also because I dont posses the money to make or maintian anything larger at the moment. I am going to build the cannon out of 930 Naval Brass, the demensions will be as follows 2" over all length / OD .750" / .177" Bore an 1.500" deep making the wall thickness about .573" Okay so the questions I have are 1. What granulation of Goex powder would be best for this cannon? 2. Should I use a patch with the bb or just a wad? 3. What would be a safe load of black powder? Any design flaws or adjustsmtents I need make would be appreciated
