Lee Precision Micrometer Neck Sizing Die Set Features The Lee Precision Collet Neck Sizing Die included in this set sizes only the neck of the 6.5 Creedmoor cartridge against a precision mandrel which eliminates the need for case resizing lubricant and ensures the case body remains properly fitted to the firearm s chamber. This approach to neck-only sizing is highly regarded among precision shooters because it reduces unnecessary working of the brass extending its usable life across more reloading cycles. The micrometer seating die in the set features a floating bullet guide along with an easy-to-read laser-engraved micrometer thimble giving the reloader infinite adjustability for precise and repeatable seating depths. This dead length seating design assures a precise uniform seating depth shot after shot which directly contributes to tighter more consistent groups downrange. The floating bullet guide in the seating die keeps the case mouth and bullet in perfect alignment during the seating process with built-in radial clearance that allows the guide to self-align with the bullet seater screw. This guide is also reversible an exclusive Lee feature that allows the die to perform simultaneous seating and crimping when the guide is removed and reinstalled in the opposite orientation. Sized for 6.5 Creedmoor with a .264 inch bullet diameter this 2-die set gives reloaders the tools needed to produce match-grade ammunition without purchasing separate sizing and seating dies. Built for shooters who demand consistency and minimal bullet runout the Lee Precision Micrometer Neck Sizing Die Set for 6.5 Creedmoor is available for sale at GrabAGun.
