old bullet, but from what kind of gun?

[renogeoff]

found this in an area that goes back to around 1860 near Reno. Couldn't find any coins yet. It looks like it came from some type of revolver. 3/4 inch long.

It looks more like a cap or a finial than a bullet.

Ditto.

You're right. I thought it was lead, but after scraping it it looks brass, and I cleaned out the hole on the bottom and it's threaded.
So used to digging bulleted around here, but I thought this one was strange for a "bullet"!
