Clueless: first thought a cannon ball

[Scrappy]

It's small, elliptical, and solid iron. It's a little larger than a jumbo chicken egg and came from a fort that ages back from colonial to civil war. One end may have something metal broken off of it.


End of a flag staff?
Ramrod for cannon?
Iron fence post tip?
Iron bull testicle?

Can you put something next to it for size reference like a quarter, it will help.

Hopefully the lightbulb will create thought (I couldn't resist).

It might be a bed knob.

A grenade? hahaha. Odd find. Maybe part to a fence post tip
