I recently switched from a manual lathe case trimmer to Lee's hand held trimmer. I like it better and it's faster for me. I have noticed the mandrel used by the Lee setup always trims cases to a length a few 1000's longer than my reloading guides (i.e. Sierra, Lyman & hornady) specify. Example: .308 recommended trim length is 2.005 with a max. case length of 2.015. The Lee mandrel produces a consistent case length of 2.009. Do I grind down the tip of the mandrel by .004 to get the recommended 2.005? Does Lee deliberately set the mandrel a little longer to account for wear? Lee doesn't provide a support email address or telephone number. So I thought I'd post here to get feed back, better yet a veteran user of this style Lee case trimmer. Any and all input is appreciated.
