Projectile was manufactured in the Federal arsenals following the design of John Dahlgren. The pattern employed a lead cup sabot with a groove in the middle on which greased twine was affixed, this to lubricate. The bottom of the projectile was cast with five ribs onto which the lead cup sabot was affixed. In addition four raised ribs were placed on the side, which were slightly wider than the rifling grooves in the cannon and designed to guide the projectile through the bore, but without catching on the grooves. These projectiles were cast with a cavity, this pattern was drilled drilled and fitted for fuze, however none have been recovered with a fuze.Projectile measures: diameter 3.95in., length 8.5in. (excluding fuze), weight 19.8lbs. Sabot is not fired and intact, remnants of lubricating twine remain. Threaded fuze not installed. Metal is solid, Projectile is disarmed: open fuze hole exposes empty interior. Recovered: surplus stocks.
