Lee Precision Micrometer Precision Bullet Seater Features The Lee Precision Micrometer Precision Bullet Seater functions as a dead length bullet seating die meaning the die body contacts the shell holder to assure a precise and uniform seating depth on every cartridge. This approach has been tested to produce cartridges with minimal bullet runout directly contributing to tighter more consistent accuracy at the range. The laser-engraved micrometer thimble and die body are easy to read with graduated divisions representing one thousandth of an inch giving reloaders the same level of precision found on a dedicated depth micrometer. This allows for infinitely adjustable seating depths tailored to a specific rifle s chamber and throat for optimal accuracy. The bullet seating stem is machined and burnished to seat nearly any point style bullet without damaging or marking the projectile during the seating process. A floating bullet guide holds the case mouth and bullet in perfect alignment throughout seating with built-in radial clearance that lets the guide and case align naturally with the seater screw. This floating guide is reversible an exclusive Lee feature that allows the die to perform simultaneous seating and crimping simply by removing and reinstalling the guide in the opposite direction. Built specifically for the .308 inch diameter bullets used in 300 Weatherby Magnum the Lee Precision Micrometer Precision Bullet Seater is available for sale at GrabAGun for precision reloaders.
