Strange bullet among other CW types

Any ideas on what kind of bullet this is? Found among others easily ID'd near Aldie, VA. Threw in a 58 caliber 3-ringer on the far right from Petersburg, VA area to show size. Appreciate it!

It's a cast bullet like the others, but post civil war. Lyman has one similar to that they call a maxi-ball.

Yup, fired Thompson center maxi-ball
