[QUOTE="Michael Eichele, post: 130561, member: 1007"] Sounds to me like you have excessive runout (crocked necks). This will cause this. If your Savage has more clearance than your 700, they will chamber easy. If your 700 is somewhat tight, the crocked necks and also bullets will cause MAJOR resistance. That is why new cases go in so easy. The minute you touch those cases with an expander ball, youre hosed! You will need to throw away the expander ball and turn your necks down to where when you run them trhough the full case sizer, the necks are sized for .002-.004" neck tension. If your dies are too tight in the necks for this, you will need a body die and then neck size with a Redding type S and the right bushing. Hope that helps! Good luck! Been that, done there!!
