Where can you find Cannon Balls for a 1inch bore cannon?
Look in the Blackpowder Cannons links list in the stickies. There is a listing for cannon balls for shooting and I think the 1 inch supplier is Magnet man or something lioke that.
Work of caution on 1 inch. Measure you bore. If you bore is 1 inch a one inch ball will not fit. You need a smaller ball. I had Jeff tanner make me a .987 diameter round ball mould for my 1.012 diameter bore.
If you bore is 1.000 then you will need a ball of of .975 for the correct windage. THe balls Magnet man supplies are 1.000 fo rthase the bore should be 1.025, allthough I have fired the 1.00 balls in my 1.012 bore with out a problem.
Some thing you might want o consider is getting some 4 bore wads to shoot with the balls.
