The Springfield Minie Ball was designed with three grooves or cannelures with a cavity at the base consisting of a perfect cone. It was .5775cal in diameter and weighed 500 grains.
Our reproduction rounds by Captain Carney are .575cal, 460 grains with three grooves, are lubricated with beeswax and tallow and have a hollow base. They are boxed in quantities of 25. We recommend you pair this with either our paper tubes or the Jefferson Arsenal packs. THESE ARE NOT FOR USE, AND SHOULD NOT BE CARRIED, FOR REENACTMENT BATTLES
