Description
If you run a 6mm XC and reload for accuracy, the trim step matters just as much as your powder charge. The L.E. Wilson 6mm XC Fired Case Holder (part number CH-6XC) is the caliber-specific piece that drops into your Wilson case trimmer and holds the case in a chamber-style pocket. Instead of gripping by the rim or case head like some systems, Wilson holders cradle the brass by its own body taper, which keeps everything aligned to the cutter axis and gives you that clean, square cut reloaders are after.
How the 6mm XC Fired Case Holder Fits Your Workflow
This is the FIRED version, which is cut slightly larger on the inside than a NEW holder. That extra room matters once your 6mm XC brass has been shot and neck sized, since fired cases run a touch wider than fresh factory brass. The larger internal taper lets the case seat properly so the neck still protrudes far enough for the cutter to do its job. Drop the case in, give the rim a light tap on the bench to seat it fully against the taper, and you are ready to trim.
Why Reloaders Reach for the Wilson 6mm XC Case Holder
Accuracy-minded handloaders lean on Wilson gear because the tolerances are tight and the results repeat batch after batch. The holder simulates a rifle chamber, so the case cannot shift or wobble while the cutter turns. Pair it with a Wilson Stainless Case Trimmer and micrometer stop and you can dial trim length in .001 inch increments, which is exactly the kind of consistency that pays off in load development and long string matches.
Keep in mind each caliber needs its own holder, and this one is built specifically for the 6mm XC (sometimes listed as the Tubbs 6XC). It is made in the USA and built to outlast the brass you run through it, the kind of simple, do-one-job-well tool that earns a permanent spot on the reloading bench.

Frequently Asked Questions
What is the difference between the FIRED and NEW 6mm XC case holder?
The FIRED holder is reamed slightly larger on the inside to accommodate brass that has been shot and neck sized, since fired cases run a touch wider than fresh factory brass. That extra room lets the case seat deep enough that the neck still protrudes for the cutter. If you are trimming once-fired, neck-sized 6mm XC brass, this is the holder you want.
Will the 6mm XC Fired Case Holder work with my Wilson trimmer?
Yes. It is designed to drop right into the L.E. Wilson Case Trimmer and sits atop the trimmer's rods, keeping the case aligned along its axis for a square cut. It is caliber specific, so it pairs with the Wilson trimmer base but not with the micrometer or crank assembly, which are separate parts of the tool.
How does the case holder actually grip the case?
Wilson holders cradle the case by its own body taper rather than clamping the rim or case head. This chamber-style design keeps the brass centered and prevents it from shifting while the cutter turns. Just insert the case and tap the rim lightly on the bench to seat it fully against the taper before trimming.
Can I use this holder for other reloading steps besides trimming?
The holder is built mainly to secure brass for case trimming, but the same alignment makes it handy for related neck and mouth prep like deburring and chamfering once the case is held. Each caliber requires its own holder, so this one is dedicated to the 6mm XC. It will not fit other cartridges.
