[QUOTE="bigedp51, post: 1419658, member: 28965"] The shoulder location on new belted cases can be all over the place because the belted case does not headspace on the shoulder. Meaning check the shoulder location "after" the case has been fired. The sizing method and the OAL will vary depending if you neck size or full length resize with minimum shoulder bump. I full length resize all my new cases to make sure the case body and neck is concentric and then trim to minimum case length and deburr. After the first firing the trimming will depend on case growth, sizing method, and if you wet tumble and ding up the case mouths, etc. [/QUOTE]
