Description
If you're running a Wilson Case Trimmer and loading for the 204 Ruger family, the CH-204R is the piece that makes everything line up. This is the fired case version, machined to hold neck-sized and fired brass by supporting the body of the case much like the chamber of your rifle. That full-length support is where Wilson earns its reputation, because the case can't wobble or tilt while the cutter does its work, and that translates straight into consistent trim lengths from the first case to the last.
The holder covers three chamberings with one piece: 17 Tactical, 20 Tactical, and 204 Ruger. It's precision machined for repeatable results, so once you've got your trimmer set, you can run through a pile of brass knowing each one comes out the same. Using it is simple. The case presses into the holder, gets trimmed, and then taps right back out by knocking the case mouth against a firm surface. A lot of folks keep a wooden dowel on the bench for pushing cases in and out without marring anything.
What the CH-204R Does Beyond Trimming
This holder isn't a one-trick part. It locks your brass in place for primer pocket reaming, neck reaming, and deburring when paired with the L.E. Wilson Uniform Deburring tool, which is sold separately. If you already lean on Wilson gear for case prep, this slots right into that workflow.
Fired Case Fit Notes for the 204 Ruger Holder
One thing worth knowing: this is the fired case holder, meaning it's cut to work with fired and neck-sized brass. Wilson makes a separate new case holder (NCH204R) for new and full-length resized cases, so match the holder to how you prep your brass. Get the right one and you've got a case prep setup that handlers and benchrest loaders have trusted for decades.

Frequently Asked Questions
What cases does the CH-204R case holder fit?
This holder is made for the 17 Tactical, 20 Tactical, and 204 Ruger. It's the fired case version, so it's designed to work with fired and neck-sized brass in those chamberings.
Does the 204 Ruger fired case holder work with new or resized brass?
No. The fired case holder is cut specifically for fired and neck-sized cases. If you're trimming new or full-length resized brass, you'll want Wilson's new case holder for the 204 Ruger (NCH204R) instead.
What trimmer does this case holder work with?
The CH-204R is built to run in the L.E. Wilson Case Trimmer. It supports the full body of the case much like a chamber, which is what gives Wilson trimmers their consistency.
Can I use the case holder for anything besides trimming?
Yes. The same holder keeps your brass steady for primer pocket reaming, neck reaming, and deburring when you use it with the L.E. Wilson Uniform Deburring tool. That tool is sold separately.
