Bruce the Badger Blasting Cannon roars it's might roar.

Oh, we stared at 75 yards when we took the pictures and hit the target from 125 yards. Just don't tell Red Badger, given his advanced age and diminishing eyesight, he will still believe that we hit the target at 1,000 yards....

I did like the photo shop work you put up.... 

Concrete is the way to go if you can't get proper cannon balls... and a brass monkey...

To photo shop something I would actually have to have the ability to run Photoshop, or whatever it is, an ability in which I am sorely lacking. That is a target I made the night before, a 48" X 48" target area standing 72" tall. Almost as tall as our one eyed leader. But I digress, since you have a cannon of roughly the same bore as mine (1 3/4" if I remember correctly) so where does a budding artilleryphile find such things? I have been searching Ye Old Net and outside of overpriced (probably fake) civil war era cannonballs I have really not found much. If one has a proper fitting cannonball, does one patch it like a PRB? Or is it meant to loosely and casually roll down the barrel held in place solely by the law of gravity? (That is a rule I always obey) If one does find a metallic or maybe even a plastic canister that just barely glides down the smooth sides of the barrel, is it lubed or dry? I have many questions and look to our fearless but squinting leader for answers.

Check for ball bearings. They come in a variety of PRECISE sizes and materials.
Here is one place I found in California that makes balls from a WIDE range of materials, including cast iron. Didn't see a price list but a phone call is cheap.
