Lee 90139 Case Length Gauge w/ Shell Holder 308 Win

The Lee 90139 Case Length Gauge is a dedicated .308 Winchester reloading tool that combines the caliber-specific gauge body with the matching shell holder in one handy 2-piece set. Drop a sized, unprimed case into the included shell holder, seat the assembly into the gauge, and you have a precise bench setup for trimming cases and squaring the case mouth in a single pass.

Built for use with the Lee Cutter and Lock Stud (or the Lee Zip Trim), the gauge has its trim length pre-set for the .308 Winchester cartridge. The cutter bottoms out on the lock stud the moment the case reaches the correct length, trimming between 1.995" and 2.015", so every piece of brass comes out identical and uniform without calipers, reading scales, or trial and error. That consistency is what keeps your reloads feeding, chambering, and shooting to spec.

Machined from steel with a silver finish, the 90139 is sized for a single .308 Winchester / 7.62x51mm NATO shell at a time and is intended as a dedicated tool for that caliber. It is a standard piece of gear for any handloader working with this popular rifle cartridge, and the fastest way to set up a .308 Win reloading bench for accurate case prep.
