Modern or civil war bullet

[Ninjafossils]

I found this bullet by a rock wall. It has NO rings. Is it an old bullet (like an enfield) or maybe modern.

Your bullet is for sure modern.

Duggap is correct. More specifically, your bullet is a copper-jacketed .45 ACP bullet, strictly 20th-Century. The copper jacket covers the lead bullet's body, except for its base (where you can see the lead).
