I have reloaded for many years with much success on various calibers but have not been able to finess my load to a consistent state for this rifle. Some days at the range are decent, other days not so much. After suspecting something was amiss with my rifle or my die set, (it couldn't be me) I recently purchased an RCBS Precision Mic to measure the headspace of my rifle and also to use for measuring distance to lands. It was easy to use and functioned flawlessly. I discovered that my .325 WSM chamber was to ANSI standards. I also discovered that my RCBS FL reloading die set was resizing my brass longer than the chamber of my rifle. I since have purchased a Neck Sizing die and will try resizing brass with that. Just need to fireform some brass. I know the FL die can be turned 1/8 to 1/4 of a turn further down and cam over to help neck size, in fact this is what I found was more accurate. Now the Neck sizer die.
Anyone use the Prescision Mic? Any stories, good or bad? Thanks in advance.
