[QUOTE="257RobertsMan, post: 1851607, member: 111366"] As others have stated, use a fired case and deprime without re-sizing, measure from datum, partially insert a spent primer and close the bolt and remeasure using the primer as the base. Or take one piece of your brass and neck size only, after 2-3 more firings of the neck sized brass the bolt lift will show some resistance due the the brass being fully sized to your chamber. While doing this check your over-all case length and trim if needed. [/QUOTE]
