I see you are brand-new here, so first I'll say "Welcome to TreasureNet!"
Now, about the metal (presumably iron) ball you found:
Cannonballs and pre-20th-Century grenades did not have an "indented" seam on them ...which your ball has.
Does a magnet stick to it?
Also ...though you did not tell us the ball's diameter, I thank you for precisely measuring its weight (1.11 pounds). Next, we'll need the ball's precise diameter (in at least tenths-of-an-inch) to be able to calculate with certainty whether it is a solid one or has a cavity inside it. Perhaps that will help is figure out what it actually is.
In your first post, you said it weighed 1.11 pounds. Now that you've corrected that to 1 pound 11.4 ounces (a major difference), I can say with certainty that it is a Solid (not hollow) ball. That, of course, excludes it from being an artillery projectile or grenade.
The projections on opposite sides from each other make me think it was mounted on something. Perhaps it is a piece of Ornamental Ironwork, such as part of a fireplace andiron.
