This is the best explanation I've seen so far. In my short 4-yr experience working at a cement manufacturing plant (Alpha Portland Cement Co.), I don't recall seeing a crushing/grinding ball that large (5" dia.), but of course my experience is limited, and it was many years ago. I read somewhere about mortar rounds with indentations so that they could easily be picked up with tongs, as well as to facilitate stacking. But I agree with you, and like I said earlier, it's the round protrusion that's a mystery to me. It's likely a discarded crushing ball that didn't get used. Why and how my cousin came by it, I'll never know.
I think Fred hit the nail on the head. It's not hollow, is it?
No, it's not hollow. It weighs 16 lbs, per our bathroom scales.
Here's a closer pic of the protrusion; if you can make it out, it almost looks like it has a tail, like the shape of a comma. Also, the spot that I thought was just discoloration looks like dried epoxy, as though there was a hole that got filled in. One thing for sure, I ain't gonna be digging on it to see if it's a hole.

We integrate ball mills in some of our systems and I've never seen one that large either. But this is for breaking ore in to gravel - the larger the ball, the larger the spaces between balls, the larger the broken down particles.
The big black cylinder being set in this photo is a ball mill we installed in Canada two years ago. It mills fly ash and bottom ash from a coal-fired power plant into fine powder that can be used for concrete or roadbed stabilization.

Pretty much every large ball mill I ever saw had what appeared to be large spikes on the drum, sort of steampunk or Mad Max style. I presume they are actually mounting bolts for the interior baffles.
But, anyway, I think I'm going to call this thing a 19th century 18 lb mortar round, and just go with it.

Then not a mortar round. I was thinking that protrusion could have been where the plug was placed on an incendiary mortar that when "phut" instead of "kapow."

I'm voting with Fred on this one.
Me too...its a "protein energy bar" Oh wait...I saw Snickers and forgot what we were talking about....

I was hoping it came from a Texas independence cannon.
