Newbie here. I bought a Black powder cannon and need some help. It arrived with no flash hole. The canon's barrel is 29.5 inches to the rear seam has a 1.5 inch bore and the bore length is 28 inches. How far forward of the end should the flash hole go and what should be the diameter....5/16?? Any help appreciated. Rick.
