Wow! Thanks for the good advise. I set my .308 sizer for the just a tiny bit short of the shoulder for the 7x57 and run them through and then through the 7x57 form/trim die and cut them off. I will then trim them and run them through the 7x57 FL sizer. I only did 20, but got 100% good cases. Forming cases is something I'm new at, I've only necked down 30/30 to 7/30 Waters, but that doesn't require moving the shoulder back. Thanks again!
