Rifling is the spiral pattern cut down the length of a firearm's barrel, which causes the projectile to spin and stabilize in flight. Bore refers to the inside diameter of the barrel, lands are the raised portions between the grooves in the rifling, and caliber markings designate the specific size of the firearm's barrel.
