HELP IDing a piece a lead

[HighTone]

Hunted a civil war camp friday dident find much but this piece a lead has me baffled. Its the same diameter as a 50 cal bullet. Any help would be great.

I've heard it wasn't uncommon for soldiers to carve trinkets out of bullets. Kinda reminds me of that.

That's a six ring I don't know bullet. THAT'S COOL. Put it on what is this, see what they say. Nice lead.
