✅ SOLVED Civil War bullet-but what type?

[DownNDirty]

I found this today at a site where I've found over 100 dropped Union bullets. All the others were .58 caliber rifle bullets. This one is shorter and has two rings. It has been flattened on one side but the best I can tell it's a .52 or.54 caliber. One of the pictures shows it next to a .58 caliber Williams Regulation.

Maybe .58 Union Repeating gun. AKA Coffee Mill gun. Missing the zinc plunger missing.

Or a williams cleaner missing the plunger.

Great call Stef-it's a Williams Cleaner with the bottom part missing. Must have separated when it was run over. Thanks!
