Cannon Ball ID ?

[100acre]

I got this in south central Louisiana many years ago hanging out with my cousins. Can anyone help me ID it? It's a solid shot. 4" half way round and weighs Two lbs. Other than that, I have no idea. Thanks

I don't have a diameter tape but I think it's more like 4" half way.

Pete "Thecannonballguy" will see this post soon and be able to help you. I think he is going to need the weight of it to determine what it is

You'll need to do super-precise measuring of the ball's diameter (in hundredths-of-an-inch) and weight (in pounds and ounces). When you've gotten those measurements, go to the following webpage and look for an exact matchup with the diameter and weight of a historical cannonball.

I co-wrote a detailed instructional article on how to tell if a metal ball is an artillery ball (cannonball, grapeshot ball, canister-ammo ball) or not. The article includes helpful photos and instructions for how to do super-precise measuring. You can view it online for free at:

There are literally multi-millions of civilian-use and industrial-use iron/steel balls, such as:
Mining Industry rock-crusher balls,
Sports Shot Put balls,
machinery counterweight balls,
Ornamental Ironwork balls
cement delivery truck tank cleaner balls,
ball-bearings (some are quite large).

The only way to tell if a ball is an artillery ball instead of a civilian ball is by super-precisely measuring its diameter and weight, then seeing if there's a matchup for it in the historical artillery ball size-&-weight data.
