Hardened steel case length gage and shell holder for .338 Federal brass. Precision-crafted to SAAMI specs for accurate trimming and case mouth squaring.
Reloaders who demand precision understand that case preparation is foundational to consistent ammunition. The Lee Case Length Gage and Shell Holder system provides the tools necessary to trim and square your brass with confidence.
Proper case length directly affects pressure curves, velocity consistency, and overall accuracy. Cases that are too long can cause excessive pressure; cases that are too short may not seal properly in the chamber. Squaring the case mouth ensures the bullet seats concentrically, reducing runout and improving downrange performance.
This combination of tools takes the guesswork out of case preparation, allowing you to focus on the precision that separates good ammunition from great ammunition.
