IIRC, the Lee inside neck reamer was an offset design that removed more metal from the thick side of the neck. I've never owned or used one so I can not be certain.
Again, IIRC, the Hodgdon Data Manual No. 26 had an article by G. Sitton about case prep for factory/hunting rifles. I believe that Gary was spot on in his recommendations and he did not call for a lot of exotic case prep. Most rifles will not benefit all that much from bench rest case prep procedures. Most factory/hunting rifles can not be made to shoot 0.25" groups unless you know a good smith experienced in BR standards, throw away the barrel, stock and the bolt innards. The action will then be trued and match grade parts can be installed. Be prepared to spend more than $3,000 and that does not include scope and mounts.
