Bigej, first let me say, welcome to TreasureNet, and to the What-Is-It forum.
As my posting-name indicates, cannonballs -- and other projectiles -- have long been my specialty-area of relic study. Check the "About me" info in my Profile here at TreasureNet. I hope you will accept that info as trustworthy credentials for saying there have never been any cannonballs which have two holes located on opposite sides of the ball from each other.
Also, your ball's size-to-weight ratio tells me it is a Solid (not hollow) ball -- and there's no purpose dor such holes in Solid-Shot cannonballs.
Your ball is either from an old weightlifter's dumbell, as Diggumup mentioned, or perhaps from a construction-crane's cable.
