The L.E. Wilson Case Gage for 6mm Dasher is a precision measuring tool every reloader should have on the bench. Whether you're setting up a new full-length resizing die or simply verifying that your fired brass is within spec, this one-piece gage gives you the accuracy you need to avoid one of reloading's most common and costly mistakes: oversizing your brass. By quickly checking headspace and overall length, you can dial in your dies correctly the first time and extend case life by keeping shoulder resizing to the absolute minimum required.
Brass quality and proper headspace control are fundamental to safe, accurate ammunition. A fired case's headspace can shift after firing, and if you're not monitoring it, you'll inadvertently work-harden and oversize your cases—shortening their lifespan and risking dangerous pressure spikes down the road. The L.E. Wilson gage pairs with a standard caliper to give you precise datum-to-head measurements and overall length checks, eliminating guesswork and building confidence in your die setup.
This is a simple, durable tool that serves one purpose exceptionally well: keeping your 6mm Dasher brass within specification so you can reload safely and sustainably. It's the kind of small investment that pays for itself in preserved brass and brass that lasts through multiple loadings.

Frequently Asked Questions
Why do I need a case gage if I'm already resizing?
Resizing dies can creep out of adjustment or be set too aggressively, causing brass to be oversized. A case gage lets you verify that your setup is correct and that your fired brass is still within safe headspace limits. This catches the problem before it wastes good brass or creates pressure issues.
Do I need a caliper to use this gage?
Yes. The gage serves as a reference tool; you'll use a standard caliper to measure the gap between the gage's datum surface and your case's head, and to check overall length. This gives you precise, repeatable measurements.
Is this gage specific to 6mm Dasher?
Yes. This gage is designed specifically for 6mm Dasher cases and will not work for other calibers.
What's included in the box?
The package contains the gage itself and a set of instructions, packed in a cardboard box.
