The Remington Zouve rifle was one of the 1st true rifles used during the Civil War (having a thicker and shorter barrel than a rifle musket). A 58 caliber, it shoots the same 500 grain Minie ball as the more common Springfield and Enfields.
Here Sarah shoots a replica Zouve using real black powder and Minie ball cast from a Lee mold that we carry at the store. Recoil is surprisingly light due to the weight of the rifle.
