Bullet ID

[relic nut]

Found this bullet today at a site where we have found some very old relics. I have found the hammer from a flintlock gun and some pre CW buttons. Have found a few Confederate block I buttons and one CS Richmond Sharps bullet. This was the site of an old settlers fort. Found this bullet today, it has two rings, is flat on the bottom and measures. 58 at the base. Thanks for any help.

Looks like a Burnside to me, but they are 54 cal. Thanks for sharing.

MAYBE A SHARPS OR BURNSIDE /?
