That info makes it look like the dimpled cannon ball was probably dug out of the ground and the dimpling is due to "the migration of elemental iron to a new location on the surface of the ball where rust scale (iron oxide) is formed". |

I'll have to go back to the pub and get some better photos.
It's a hard life!

Dropped in for a pint at my favourite pub yesterday and took some more photos of the cannon ball, and it certainly looks like the marks were put there for a reason?
The indents follow a regular pattern all around the ball and it weights around 100 lbs.
Close up of the marks a lot of which seem to have a triangle shape.
I put my pint in the photo to get some idea of scale ( mmm... Duff! )
For anyone passing and wants to take a peek at this missing link in the world of ballistics, you can find it here. Or just get pissed?
