Actually, it is the correct diameter to be a 24-pounder Grapeshot ball. The data in the 1861 Ordnance Manual covers cannon ball sizes from the Revolutionary War all the way up to 1861. Check the Grapeshot size-&-weight chart at:

However, despite your ball's correct diameter, you mentioned other characteristics (a flat spot, and some erratic dimpling) which usually tend to disqualify an iron ball from being any type of cannon ball. There is no such thing a "flattened" area (from impact) on iron cannonballs -- because the cast-iron they are made from tends to shatter rather than get flattened by impact.
Also, you say your ball's precisely-measured weight is 2.01 pounds. But the Ordnance Manual says a 2.62-inch ball weighs 2.4 pounds (2 lb. 6.4 ounces). In other words, your ball should weigh 20% more than it does. When an iron ball's weight is THAT seriosuly "off" from the Ordnance Manual's specifications, there is good reason to suspect it is not a cannon ball.
BUT... all of that having been said... well-lit, well-focused, close-up photographs would be very helpful. No offense intended, but in artifact authentification, there is no adequate substitute for SEEING rather than relying on a written description.
