If you reload for the 6.5 Grendel, this little piece of polished steel earns its spot on the bench fast. The L.E. Wilson Case Gage is a one-piece, non-adjustable cylinder cut to SAAMI minimum chamber dimensions, so you can drop a case in and immediately see where your brass stands on both headspace and overall length. It takes the guesswork out of setting up your full length sizing die, which is where a lot of folks run into trouble oversizing their brass and shortening case life.
The process is straightforward. You drop a fired case into the gage and measure the headspace, either with a depth micrometer or a caliper depending on whether the case sits high or low. From there you slowly dial in your full length sizer until you see a thousandth or two of drop in headspace, which puts your shoulder just below your chamber's actual dimension. That means brass sized for your rifle, not overworked past what it needs. Flip the gage head-down on a flat surface and you can eyeball the case mouth against the milled step to check whether it needs trimming.
L.E. Wilson has been building these cartridge gages since 1935, when founder Sam Wilson came up with the design to help a fellow shooter solve a case separation problem. That heritage shows in the machining. The tool itself is simple, there's nothing to adjust or wear out, and it gives you a repeatable reference every single time. For a cartridge like the 6.5 Grendel that gets run hard in AR platforms and bolt guns alike, keeping tabs on shoulder bump and trim length is what keeps your brass alive and your groups honest.
One thing worth knowing: this gage checks headspace and length, not body diameter, and it's meant to be used with fired cases as your starting point. Pair it with a quality caliper or the matching Wilson depth micrometer and you've got a complete picture of what your sizing die is doing.
It checks two things that matter most when reloading: case headspace (the datum-to-head dimension) and overall case length for trimming. It does not measure case body diameter. Think of it as your reference point for setting up a full length sizing die correctly.
Drop a fired case into the gage and measure the headspace with a caliper or depth micrometer. Then adjust your full length sizer until you get about a thousandth or two of shoulder bump, which sizes the case just under your chamber. This prevents oversizing and helps your brass last longer.
No, this is the one-piece, non-adjustable style cut to SAAMI minimum chamber dimensions. L.E. Wilson's adjustable gages are a separate design made specifically for belted magnum cases. For the 6.5 Grendel, this fixed gage is exactly what you want.
Yes, the gage gives you the reference surfaces, but you'll measure against them with a caliper or a depth micrometer. The matching Wilson case gage depth micrometer pairs with it for the most precise readings, though a good caliper gets the job done for most reloaders.
