This is a very unusual projectile.  In the opinion of the author of this website, this projectile is a Confederate adaptation of the Selma or Read pattern employing a lead, cast on sabot. It seems that Tredegar Iron Works (in Richmond, Virginia) manufactured cannon that correspond to this type of projectile.  Comments are welcome
