If you run an L.E. Wilson case trimmer and load 300 AAC Blackout, this is the holder that makes it all work. L.E. Wilson has been machining case holders and trimmers since the 1930s, and the design here is refreshingly simple: a precision-cut holder that supports the case body much like the chamber of a firearm. That full-body support is what keeps your brass in perfect axial alignment with the cutter, so trim lengths come out consistent batch after batch.
Using it is about as straightforward as reloading gets. You drop the case in, tap the head lightly on a hardwood block or your bench to seat it firmly in the tapered holder, then set the loaded holder onto the trimmer rails against the stop. Because the holder only engages the case body and there's no neck pilot involved, this one unit handles trimming, primer pocket reaming, neck reaming, and deburring. When you're done, a quick tap on the case mouth pops the brass right back out.
Folks who trim with the Wilson system consistently report holding tolerances well under a thousandth of an inch, and the case holder is a big part of that. Keeping the case rim out of the equation removes a common source of length variation you'd get with rim-gripping shell holders. This is a standard holder, meaning it covers both new and full-length sized brass as well as fired cases for 300 Blackout, so you're not stuck buying separate new and fired versions.
Made in the USA from polished steel and built to last a lifetime of reloading, it's a small tool that punches way above its size. Keep the inside and outside clean before each session and it'll keep turning out uniform, match-ready brass for as long as you're loading Blackout. Pair it with your Wilson trimmer and a good chamfer tool and you've got a trimming station that's hard to beat.
Yes. This is the standard CH-3ACC holder, which is designed to fit new, full-length sized, and fired 300 AAC Blackout cases. L.E. Wilson only splits holders into separate new and fired versions when a caliber needs it, and 300 Blackout is covered by this single unit.
Yes, the case holder is made to be used with the L.E. Wilson case trimmer. It sits on the trimmer rails and supports the case body during trimming, so it won't work on rim-gripping trimmers from other brands. If you already run a Wilson trimmer, just add the matching caliber holder and you're set.
Drop the case into the holder and tap the head lightly on a hardwood block or your bench to seat it firmly in the tapered bore. After trimming, a gentle tap on the case mouth releases it. Many reloaders keep a wooden dowel handy and tap cases in and out at a clean spot to avoid getting brass shavings on the case base.
It can. Because the holder supports the case body like a chamber, it keeps the brass aligned for trimming, primer pocket reaming, neck reaming, and deburring. That makes it a versatile part of your 300 Blackout reloading bench rather than a single-task tool.
