Lee Precision 92247 Micrometer Bullet Seating Die /Clear 6Mm Cm Rifle Firea

The Lee Precision 92247 Micrometer Bullet Seating Die for 6mm CM brings precision reloading control to your bench without the premium price tag. This micrometer bullet seating die uses a dead-length seating method that locks the cartridge body against the shell holder, ensuring repeatable, uniform seating depth every time you cycle the press. The laser-engraved micrometer thimble and body read in one-thousandth-inch increments—just like a precision depth micrometer—so you can dial in exactly the seating depth your 6mm CM loads demand.

The floating bullet guide is the key to this die's accuracy. It holds the case mouth and bullet in perfect alignment while allowing radial clearance so everything centers naturally without binding. That design pays off in minimal bullet runout, the kind of consistency that tightens groups at distance. The bullet seating stem is machined and burnished smooth, so it seats virtually any bullet point style cleanly, without marks or deformation. Need to seat and crimp in one stroke? The floating guide is reversible—just unthread and reinstall it to flip between seating-only and combined seating and crimping modes, an exclusive Lee feature.

Whether you're handloading match ammo for the range, precision hunting rounds, or working up loads for a new 6mm CM rifle, this micrometer die gives you the adjustment resolution and control that separate average loads from excellent ones. It's the kind of tool that rewards attention to detail without requiring a second mortgage.

Frequently Asked Questions

Will this die work for both seating and crimping?

Yes. The floating bullet guide is reversible. In its standard orientation, it's a seating-only die. Unthread and reinstall the guide in the opposite direction to enable combined seating and crimping in a single stroke—a feature unique to Lee's design.

What makes the micrometer thimble better than a standard seating die adjustment?

The micrometer thimble is laser-engraved and reads in one-thousandth-inch divisions, just like a precision depth micrometer. That means you can dial in exact seating depths and return to them consistently, shot after shot, without guessing or relying on feel.

Can this die seat different bullet designs without damaging them?

Yes. The bullet seating stem is machined and burnished smooth to seat virtually any bullet point style cleanly, without marking or deformation to the projectile.

What does the floating bullet guide do?

The floating bullet guide holds the case mouth and bullet in perfect alignment during seating while allowing radial clearance so everything centers naturally. This design minimizes bullet runout, which translates to tighter groups and more consistent ballistics.
