Lee Precision Collet .223 Rem Steel Neck Sizing Die - 90954

Overview

The Lee Precision Collet Neck Sizer Die for .223 Remington is a precision reloading tool designed to enhance ammunition accuracy and extend brass life by sizing only the case neck. Utilizing a collet mechanism that squeezes the brass against a hardened steel mandrel, the die creates a precisely aligned case neck with minimal runout while preserving the original case shoulder geometry. This method eliminates the need for case lubrication and ensures a uniform bullet fit. Because the neck is custom-sized to fired brass, it is recommended for use with brass fired in the same firearm chamber. The die helps handloaders achieve tight chamber tolerances, consistent bullet seating, and improved powder charge efficiency. It includes the collet neck sizer die and a storage box.
