Is this a cannon ball

[pepperj]

I found this in the centre of a cellar hole under a stone. I believe that the foundation wall fell into the hole a long time ago as there's good layer of soil built up.
Once I got the rock out this was another 6" down.

It more than likely is. Try a little cleaning and make sure its not a shot put. Look for a sprue and seam.

Any suggestions on cleaning it up, wire brush seems harsh.
Soaking it in Apple cider vinegar maybe?

Wire brush. Sometimes I use "Iron Out", but lately I just start pounding on them with a 4 ounce tack hammer to get the big stuff off, then wire brush. Yours doesn't look like it needs the hammer treatment.

Size 3 in (?) Possibly solid shot if no charge hole. Such was used to batter down walls
