Description
L.E. Wilson has been building precision reloading tools since 1927, and the Case Gage is where it all started back in 1935. The company's founder, Sam Wilson, came up with it after a fellow shooter needed help solving a case-separation problem, and the basic idea has held up ever since. This one is cut for 6/6.5 Creedmoor, so it handles both 6mm Creedmoor and 6.5 Creedmoor brass, and it does one job extremely well: it tells you exactly where your brass sits.
The way it works is about as simple as reloading tools get. Drop a fired case into the gage, set it on a flat surface, and read it. If the case sticks out past the max line, your chamber is running on the generous side. From there you can measure with a caliper or depth micrometer to dial in your full-length sizing die so you're bumping the shoulder back just enough and no more. Overdoing it is one of the most common reloading mistakes, and it's what leads to overworked brass and eventually case-head separation. Being able to see the shoulder position before and after sizing is the difference between guessing and knowing.
Why the Wilson Case Gage Earns a Spot on the Bench
This is a one-piece, non-adjustable design machined from steel, built to compare your cases against minimum chamber dimensions. It checks both headspace (datum-to-head) and overall case length, so it doubles as your trim-length reference. Flip it over, look across the top, and you've got your min and max trim marks right there. Reloaders who've switched over from cheaper gauges often mention that brass which fought them in other tools slides in and out of the Wilson cleanly.
What the 6/6.5 Creedmoor Gage Won't Do
Worth being clear: this gage does not measure body diameters. It's meant for fired and resized rimless brass to give you a basis for sizing and trimming decisions, not a full dimensional inspection. Pair it with a good caliper and it covers the measurements that matter most for safe, consistent Creedmoor handloads. Made in the USA.

Frequently Asked Questions
Does this Wilson Case Gage work for both 6mm and 6.5 Creedmoor?
Yes. The CG-65CRE is cut to handle both 6mm Creedmoor and 6.5 Creedmoor brass, since the two share the same case dimensions aside from the neck. That makes it a convenient single tool if you load for both cartridges.
How do I check headspace with the Case Gage?
Drop a fired case into the gage and set it head-down on a flat surface. If the case protrudes past the maximum line, your chamber runs larger than average, and a caliper or depth micrometer will tell you exactly how much to bump the shoulder when sizing. This lets you set your die to size just below your chamber's headspace so you avoid overworking the brass.
Can the Wilson Case Gage tell me when to trim my brass?
It can. Along with headspace, the gage checks overall case length, with min and max trim marks you read by looking across the top of the gage. If the case sits above the max line, it's time to trim.
Does the Case Gage measure case body diameter?
No, it does not measure body diameters. It's designed to check datum-to-head length and overall length on fired and resized rimless cases to guide your sizing and trimming. For body measurements you'd want a separate tool.
