Lee Precision 6Mm Remington Rifle Precision Micrometer Bullet Seating Die

The Lee Precision 6mm Remington Rifle Precision Micrometer Bullet Seating Die gives serious reloaders the precise control they need to build match-grade ammunition without the premium price tag. This dead-length seating die uses a micrometer-style adjustment mechanism that reads just like a precision depth micrometer—in thousandths of an inch—so you can dial in exactly where your bullet sits in the case, shot after shot. Whether you're working up loads for a 6mm hunting rifle or chasing groups at the range, consistent seating depth is non-negotiable for accuracy, and this die delivers it.

What sets Lee's design apart is the floating bullet guide with radial clearance. Instead of forcing the case and bullet into alignment, the guide floats freely, letting both components settle naturally into perfect concentricity before the seating stem does its work. The result: Lee's testing shows this approach produces cartridges with the least bullet runout. The seating stem itself is machined and burnished smooth, so it seats nearly any bullet profile—from hollow points to boat tails—without marring or marking the projectile.

The reversible bullet guide is a clever touch: unthread it, flip it, and reinstall it to seat and crimp in a single stroke if you're using a crimping ring—an exclusive Lee feature. The laser-engraved micrometer thimble and die body are easy to read in shop light, and the infinitely adjustable design lets you dial in whatever seating depth your load data calls for. If you're already set up for Lee's standard die system, this die threads into your press just like any other and contacts the shell holder for rock-solid repeatability.
