When muskets were rifled, the gunsmith used a bit to carve grooves in the length of the barrel. The groove is a depression cut, which created a lan, which was the uncut area. Rifling served to impart a spin on the projectile, which stabilized the flight of the bullet, helping it to travel farther and more accurately. The Minie ball, which is a conical shaped bullet, was hollow at the base, with a skirt about 1/16" of an inch thick and about 3/16 in depth. When the black powder ignited behind the bullet, the force of the explosion caused the skirt to expand, engaging the soft lead bullet into the rifling, thus causing the bullet to spin.

How is a 20 inch gun measured?
In the US, rifled guns (handguns, rifles, machine guns, and cannons (artillery) caliber is measured from "lands to lands" (inside the bore); in Europe caliber is measured from the grooves. The lands are the raised portion of the inside steel barrel (inside the bore), the grooves are the cut portion, the valleys of the bore's interior. Therefore, a 20" gun would measure close to 20 inches directly across from one "land" to the other "land." If you measure from groove to groove, the diameter will be larger.
