Lee Precision Micrometer Precision Bullet Seater Features The Lee Micrometer Precision Bullet Seater uses dead length bullet seating meaning the die body contacts the shell holder to assure precise uniform seating depth on every case. Sliding bullet guides hold the case mouth and bullet in perfect alignment which testing shows produces cartridges with the least bullet runout compared to conventional seating dies. The seating stem is machined and burnished to handle nearly any point style bullet without marking or damaging it during the seating process. That combination of alignment and gentle handling helps reloaders build more consistent accurate .300 AAC Blackout ammunition. The laser engraved micrometer thimble and body are easy to read with divisions representing one thousandth of an inch functioning just like a precision depth micrometer for infinitely adjustable seating depth. The floating bullet guide is reversible an exclusive Lee feature that allows the die to seat and crimp simultaneously simply by unthreading and reinstalling the guide. Radial clearance built into the guide lets the case and guide align naturally with the bullet seater screw rather than forcing a rigid fit. For .300 AAC Blackout reloaders who want seating precision without paying a premium price this die proves accuracy does not have to come at a high cost.
