[QUOTE="highdrum, post: 2027536, member: 13732"] You get a shoulder bump gauge, measure your fired cases(with primers decapped), and set your die to bump the should 1.5-2.5 thou back from fired dimension. Your die may slightly bump the shell holder, or in some cases it will not, depending on depth of chamber/headspace. This greatly improves accuracy and brass life, as it prevents a lot of brass stretch and thinning above the case head. Excessive sizing causes case head seperation. [/QUOTE]
