Small Base Sizer Dies are usually required for reloading ammunition to be used in automatic, semi automatic, pump, slide and some lever action rifles. These dies size the body of cases somewhat smaller in diameter and also set the shoulder back slightly more than a Full Length Sizer Die to ensure proper functioning in the actions of these rifles.
Not recommended for ammunition used in bolt action rifles.
