Lee Case Length Gage and Shell Holder .357 Mag

The Lee Case Length Gage and Shell Holder .357 Mag (SKU LEE90158) is an essential precision reloading tool designed for handloaders and ammunition manufacturers who demand accuracy and consistency. This tool is particularly useful for law enforcement armorers and competitive shooters who need to ensure that every round meets SAAMI specifications before it reaches the chamber.

Engineered from hardened steel, the case length gage is precision-machined to match SAAMI maximum and minimum case dimensions for .357 Magnum. It provides go/no-go confirmation in seconds, helping to eliminate case length variance, which is a common cause of pressure inconsistency and feeding failures. The included shell holder grips cases securely during measurement, preventing misalignment that could skew results.

This tool is indispensable for anyone running a serious reloading operation, including military and law enforcement ammunition technicians, precision handloaders, and high-volume commercial operations. All depend on case length verification to prevent out-of-spec ammunition from reaching shooters, ensuring reliability and safety in their ammunition.
