The L.E. Wilson 6.5x55mm Swede case gage is an essential single-piece tool for reloaders who want to dial in accurate headspace and catch potential case-sizing errors before they compromise brass life or safety. Whether you're prepping once-fired military brass or managing a carefully maintained personal stash, this gage lets you verify that your resizing dies are set correctly and your cases are within spec—without guesswork or expensive mistakes.
Setting up a full-length resizing die is one of the most critical steps in the handloading process, and getting it wrong is disturbingly easy. Oversizing brass stretches case life and can introduce dangerous pressure anomalies. The Wilson gage measures overall length (so you'll know when trimming is needed) and datum-to-head length (which confirms headspace is correct), giving you two essential data points with just a caliper and this tool. It's the kind of straightforward, repeatable control that separates careful reloaders from those who'll eventually push out a batch of rounds that don't fit their chambers quite right.
Built to last, this gage comes as a one-piece design with a knurled grip in the middle for secure handling. The dual-diameter bore accommodates the body and shoulder of the 6.5x55mm Swede case, letting you seat it fully for an accurate reading. Use it before you resize, after you resize, or whenever you're auditing a batch of brass—it's a five-minute check that can save your rifle, your ammo investment, and your reputation at the range.

Yes. In fact, measuring fired cases is one of the primary uses of this gage. Simply chamber a fired case into the gage and use a caliper to measure datum-to-head length and overall length. This tells you how much your cases have grown and whether your resizing dies are bringing them back into spec.
You'll need a caliper (dial or digital works fine) to take your measurements. The gage itself requires no adjustment—it's a go/no-go reference tool that you use with a caliper to verify headspace and case length.
L.E. Wilson makes both regular and adjustable styles. The adjustable gage is designed for belted magnum cartridges, where the belt provides primary headspace support. The 6.5x55mm Swede is not a belted cartridge, so this regular-style gage is the correct choice.
Chamber a fired case into the gage, measure the datum-to-head distance with a caliper, then compare it to your reloading manual's specification for the 6.5x55mm Swede. If your resized cases measure the same as a properly fired factory or previously-loaded case, your die is set right. If measurements are creeping longer, your die is positioned too high and you're oversizing.
