The Lee Precision 204 Ruger Rifle Precision Micrometer Bullet Seating Die brings repeatable, uniform cartridge assembly to your reloading bench. Built for handloaders who care about consistency, this die uses a micrometer-style adjustment system to control bullet seating depth with precision measured in thousandths of an inch—the same level of control you'd expect from a precision depth micrometer. Whether you're loading match-grade rounds for the range or hunting ammunition, the micrometer adjustment eliminates guesswork and lets you dial in the exact cartridge specifications your rifle demands.
The die's design centers on dead-length seating, where the die body contacts the shell holder to ensure consistent seating depth from round to round. A floating bullet guide holds the case and bullet in perfect alignment during seating, reducing the bullet runout that can affect accuracy. The guide features radial clearance, allowing it to self-align with both case and bullet for minimal marking or deformation. The polished seating stem handles nearly any bullet point style without damage, and the floating guide is reversible—unthread it and reinstall to set up simultaneous seating and crimping if your reloading sequence calls for it, a feature Lee reserves for this die line.
Laser-engraved markings on both the micrometer thimble and die body make reading adjustments straightforward and reliable in varying lighting. The infinitely adjustable mechanism means you're not locked into fixed positions; you can fine-tune seating depth to match your specifications exactly. This is no-frills, results-focused equipment—the kind of tool that rewards attention to detail with tighter groups and more reliable performance downrange.

The floating bullet guide holds your case and bullet in alignment during seating without forcing them into fixed position. It has radial clearance that lets the case and guide self-align with the bullet seating stem, reducing bullet runout—the wobble that can hurt accuracy. This design also prevents the guide from marking or deforming your bullets.
Yes, when needed. The floating guide is reversible: unthread it and reinstall it to set up the die for simultaneous seating and crimping. This flexibility lets you adapt your reloading sequence without buying a separate crimp die.
The micrometer thimble and die body are laser-engraved with divisions that represent one thousandth of an inch each—just like a precision depth micrometer. This infinitely adjustable system lets you dial in your exact seating depth and read it consistently every time. There are no preset stops; you set the depth your cartridge specifications demand.
The burnished seating stem is designed to seat nearly any point style bullet without marking or damage. If you have questions about a specific bullet design, contact Lee Precision directly for compatibility confirmation.
