L.E. Wilson Case Gage 6mm B-R (std) Long 1.560

The L.E. Wilson Case Gage 6mm B-R (std) Long 1.560 is a precision measuring tool built to solve one of reloading's most common and costly mistakes: oversized brass. Whether you're working up loads for a 6mm BR Norma match rifle or fine-tuning brass for long-range hunting, this one-piece case gage lets you verify headspace and overall length with the accuracy that separates consistent ammunition from problematic rounds. By catching headspace drift early—before it accelerates case wear and creates safety risks—you'll extend brass life and maintain the tight tolerances that modern long-range shooting demands.

The Wilson case gage works with a simple caliper to give you quick, repeatable measurements of both fired case length and datum-to-head distance. This dual-function approach is especially valuable when setting up your 7/8"-14 full-length resizing dies. Rather than guessing at die position or relying on generic load data, you can measure actual fired cases and dial in your dies to minimize case growth—a critical step for anyone running a progressive or single-stage press who loads for precision rifle or benchrest competition.

Built from durable materials with knurled grip sections for steady handling, the gage arrives with straightforward instructions to get you measuring right away. It's a small tool that prevents big mistakes, and it's as useful for the reloader who processes 500 rounds a season as it is for serious match shooters who demand maximum case life and safety margin.

Key Features

Frequently Asked Questions

What's the purpose of a case gage in reloading?

A case gage measures fired brass to verify headspace and overall length, two critical dimensions for safe, consistent ammunition. It works with a caliper to catch cases that have grown beyond safe limits and helps you set up your full-length dies correctly to minimize oversizing—one of the most common reloading mistakes that kills brass prematurely.

How does the L.E. Wilson gage help with die setup?

By measuring datum-to-head length on fired cases, you can position your 7/8"-14 full-length resizing die to resize only as much as necessary. This approach extends case life significantly, especially important for expensive precision rifle brass or match-grade 6mm BR components.

Can I use this gage with calipers I already own?

Yes. The gage is designed to work with standard calipers for measuring overall length and datum-to-head distance. You'll need a caliper but not any special measuring equipment.

What's included with the L.E. Wilson Case Gage?

The package includes the gage itself and printed instructions to walk you through the measurement process.
