Cannon Ball?

I found this item in at the head of a small branch on a farm. There are no residences near this area. It measures 10" around, and weighs 19 oz. the way it is. I couldn't make out a seam around it with all of the rust. Any help would be greatly appreciated.

Thanks for your response. I had hoped it was from the Civil War or earlier, but if it's not, then it's not. It's still a great find for me though. Thanks for helping me figure it out!
