Description
If you run a L.E. Wilson case trimmer and you're loading 350 Legend, this is the holder that locks your brass in place while you dial in a precise trim. The NCH-350L is the "New Case" version, which means it's bored to fit unfired factory brass and cases that have been full-length resized. L.E. Wilson machines each holder to mimic the chamber of a firearm, supporting the case by its body taper rather than the head, so the case sits in perfect axial alignment with the cutter every single time.
Why the New Case Holder Matters for 350 Legend Brass
Here's the deal with Wilson's two-holder system: a brand new or resized case is smaller in diameter than a fired one, so the holders are cut to match. This "New" holder is the right call for virgin 350 Legend brass or anything you've run back through a full-length die. Grab the Fired Case version instead if you only neck size. Using the correct holder keeps the case from spinning and gives you clean, even case mouths without the frustration.
Built for Repeatable, Precision Results
The 350 Legend being a straight-walled cartridge makes brass prep worth doing right, especially if you're chasing consistent neck tension and uniform overall length. These holders are precisely manufactured so you get the same result case after case, whether you're running a handful for deer season or prepping a big batch over the winter.
More Than Just Trimming
This holder earns its keep beyond the trimmer. The same NCH-350L works for primer pocket reaming, neck reaming, and deburring when paired with L.E. Wilson's Uniform Deburring Tool and related accessories, all sold separately. To use it, you simply seat the case in the holder, tap the case head on a firm surface, and set it into the trimmer. Pop the case out with a quick tap on the mouth when you're done. It's a simple, well-made piece of kit that holds up for the long haul on the reloading bench.

Frequently Asked Questions
What's the difference between the New Case Holder and the Fired Case Holder for 350 Legend?
The New Case Holder (NCH-350L) is bored to fit unfired factory brass and cases that have been full-length resized, since those are smaller in diameter. The Fired Case Holder is reamed slightly larger to fit brass that's only been neck sized after firing. Pick the one that matches how you prep your brass, because the wrong fit can let the case spin or sit poorly in the trimmer.
Does this case holder work with my L.E. Wilson trimmer?
Yes. The NCH-350L is designed to drop right into L.E. Wilson case trimmers and maintains perfect alignment between the case and the cutter. The same holder also works for primer pocket reaming, neck reaming, and deburring with Wilson's accessory tools.
Can I use the New Case Holder with fired brass?
It isn't recommended. This holder is cut for the smaller diameter of new and full-length resized brass, so fired cases that haven't been resized may not seat correctly. If you neck size only, go with the Fired Case Holder for 350 Legend instead.
How does the case holder actually hold the brass?
The holder supports the case by its body taper, much like the chamber of a firearm, rather than gripping the case head. You seat the case, tap the head on a firm surface to set it, then place it in the trimmer. A quick tap on the case mouth pops it right back out when you're finished.
