Lee Precision, Inc. .300 WSM Rifle Collet Neck Sizing Die

The Lee .300 WSM collet neck sizing die employs a steel collet to compress the fired case against a precision mandrel. This process ensures a precisely aligned case neck while minimizing runout. The outcome is enhanced accuracy and prolonged case life. This die sizes only the neck and does not require case lubrication. It is recommended for cases that have been fired exclusively through your firearm.
