[QUOTE="shortgrass, post: 2506778, member: 24284"] As recommended to me by Dave Manson, during one of our conversations when I was having a custom reamer made, .003" [I][B]over[/B][/I] the neck diameter of my loaded rounds was/is considered 'acceptable' for my 6XC Varmint reamer. As bullet diameter increases, more clearance is added. These numbers are for "hunting rifles".

It is not uncommon to have up to .010" clearance in a factory cut chamber. If we are talking 'factory cut chamber' we are also talking factory made barrel. Neither is the equal of a custom made barrel blank chambered by a competent gunsmith. Regardless of the neck tension you end up applying to your reloads, the diameter of the chamber neck does not change.
