[QUOTE="J E Custom, post: 502100, member: 2736"] I would recommend using a standard 280 AI reamer from Manson or PT&G. It is not easy to get a special reamer correct and the problems can be devastating. It is easy to turn the neck If it is to tight (.003 thousandths larger than a loaded round is my minimum clearance. If chambered and head spaced correctly there is little or no improvement in accuracy . Tight tolerances should be approached with caution. Fit the case to the chamber not the chamber to the case. This leaves you with many options and some flexibility. Just my opinion for what it's worth. J E CUSTOM [/QUOTE]
