Civil War dug Artillery Naval Grape shot Cannon Ball for Sale - World War Museum Artificats
This sure look like it! Google Images 'Grape Shot' You will come up with a lot of pictures that look similar. Yours looks a little smoother, but if it has been kicking around in a river bed for a couple hundred years, that might explain it.

This sounds right, Rustic. The equator like ridge that Rich described would be a parting line from the original casting process.

He said it was non magnetic - so it may be lead.

He also said it "has a few rust-looking spots on it".

Probably just a coincidence but on my last visit I said the exact same thing to my doc...

Why on earth are you telling your doc that Rich has a few rust-colored spots on his ball?
Wait... maybe I'm parsing that wrong

Well, those things that aren't used regularly often get rust on them!

The ridge could indicate that it was cast from a mold.

So far, "grape shot" seems to be the best match (used to fill cannisters loaded into Civil War era cannons).

Probably meant stainless steel. Most common types are not attracted to a magnet.

There are a few cast irons and steels that are not ferromagnetic: they are "austenitic", meaning their atoms are arranged in a face centered cubic pattern. Many of the stainless steels fit this category.
