I need the help of you knowledgeable reloaders please. I shoot a Rem mag 7mm sendero and am reloading . I am new to the belted cases and want to know how I should go about setting up my resizing die to properly form the brass for longest life and best accuracy? I am running a LEE challenger single die press with a lee resizing decapper die. Do I run the brass all the way in or do i just do the neck so I don't bulge the brass above the belt?
