Musket ball Button maybe ?

[DirtTGuy]

It is a one piece very heavy iron I thing . It has striations around the ball part.
The shank is drilled. Very odd to me ... I found ball buttons before but first one like this..

Agree that if it is iron it is likely a bell clapper.

If it is made of iron, a magnet will stick to it. Please check about that, and let us know. It is important for correctly identifying your find.

Did they not make iron musket balls? Also kind of big for a clapper

There are some mighty big bells out there.

No. They would play hell in an iron barrel. Lead is heavier, easier to make in molds, and upsets ("smushes"), sealing the bore better and also making more of a wound when it hits.
