Description

This is the raw material for a truly custom seating die. The L.E. Wilson 6mm Seater Die Blank (part number CB-60) gives reloaders and gunsmiths a finished starting point to build a chamber-type bullet seater tailored to a specific cartridge or wildcat. The bore hole comes finished for proper alignment, and the blank is intentionally made long so it can be trimmed to the correct length once the chamber is cut. A pilot hole runs through to the finished bore, giving your gunsmith a clean reference to work from.

Why Reloaders Reach for the Wilson Chamber Type Seater

The Wilson chamber-type design is a longtime favorite on the benchrest line, and for good reason. Instead of relying on a sliding collar like many conventional dies, it fully captures both the case and the bullet before seating begins. The case stays stationary while a close-fitting seating stem presses the bullet straight into the neck, which is what delivers the low runout and tight concentricity these dies are known for. Starting from a blank lets you headspace that chamber to your own fired brass for an even closer fit.

What Comes With the CB-60 6mm Die Blank

The blank ships with the cap, seating stem, and base, so once the chambering work is done you have the complete assembly ready to run. Worth noting up front: this is a hand-die design meant for use with an arbor press or a mallet, not a conventional threaded press. It also arrives unchambered, so the cartridge chamber still has to be cut by a competent gunsmith using the appropriate reamer.

Made for Custom and Wildcat Builds

If you're chasing a 6mm wildcat or just want a seater matched perfectly to your chamber and brass, this blank is the way to get there. L.E. Wilson has been building precision reloading tools for decades, and the finished bore on this blank gives your smith a true, concentric foundation to work from. It's a smart call to check with your gunsmith before ordering to confirm they're set up to do the work.

Frequently Asked Questions

Is the 6mm seater die blank ready to use out of the box?

No. This is an unchambered blank, meaning the cartridge chamber still has to be cut by a competent gunsmith with the correct reamer. The bore comes finished and the blank runs long so it can be trimmed to final length once the chamber work is complete. It's worth checking with your gunsmith before ordering to confirm they'll do the work.

What comes with the L.E. Wilson CB-60 blank?

The blank includes the die body, cap, seating stem, and base, along with a chambering guide. Once your gunsmith finishes the chamber and trims it to length, you'll have a complete chamber-type seater assembly ready to run.

Does this die work in a standard threaded reloading press?

It does not. The Wilson chamber-type design is a hand die meant for use with an arbor press or a mallet. The case sits stationary in the die while the bullet is pressed straight down into the neck, which is part of what gives these dies their reputation for low runout.

Is the CB-60 a micrometer or stainless steel blank?

No, the CB-60 is the standard chamber-type seater blank rather than the stainless micrometer version. If you want micrometer adjustment later, L.E. Wilson offers an optional micro-adjustable seating cap that can be added to the die.
