My analysis is based on the ball's 1.5" diameter and 8-ounce weight measurements you reported. Whoever told you the ball is a "24-Pounder (5.82" caliber) Case-Shot ball" is seriously incorrect. A Case-Shot shell is filled with antipersonnel balls or slugs or wedges, etc. The balls in a 24-Pdr. Case-Shot were approximately .65 to .75-inch in diameter... and were almost always made of lead. (The Confederates ran short of lead in very-early-1863 and had to use iron for case-shot balls from then on through the end of the war.)
The US Ordnance Manual of 1861 contains super-precise diameter and weight measurements charts (called the "Shot Tables") for artillery balls used from the Revolutionary War through the civil war.

The closest matchup for your 1.5-inch 8-ounce iron ball in the Shot Tables is a 12-Pounder Field Gun's Canister-Ammo ball... which was 1.465-to-1.485-innches in diameter and weighed .43-pound (7 ounces). If your ball actually does measure PRECISELY 1.5" in diameter and weigh PRECISELY 8-ounces (instead of 7), it is not an Artillery ball, it is a Civilian-usage ball (such as a ball-bearing). I emphasized the word PRECISELY because to achieve CERTAINTY of identification you will need to use "precision" measuring devices -- such as a Caliper which measure in hundredths-of-an-inch, and a Postal Shipping scale, which weighs in tenths-of-an-ounce.

I measured the ball with a caliper today and it came in at 1.525" and weight on a postal scale is almost exactly 8 ounces so unfortunately it would seem I have an iron ball of some type. Thank you again for the information!
