Lee 25-303 British Precision Micrometer Bullet Seating Die

Overview

The Lee Micrometer Bullet Seating Die for the 25-303 British cartridge provides smooth, infinite adjustments for precise seating depth control. Designed as a dead-length seating die, its body contacts the shell holder during operation to ensure uniform seating depth across cartridges. A laser-engraved micrometer thimble and body display easy-to-read divisions representing one-thousandth of an inch. A floating bullet guide holds the case mouth and bullet in perfect alignment with the seater screw to minimize bullet runout. The seating stem is machined and burnished to prevent marking or damage to various bullet point styles. Additionally, the floating bullet guide can be unthreaded and reversed to allow simultaneous bullet seating and crimping.
