The Lee Precision 444 Marlin Rifle Precision Micrometer Bullet Seating Die is built for reloaders who want repeatable, uniform seating depth without the premium price tag. This micrometer-adjustable seating die uses dead-length seating—where the die body contacts the shell holder—to ensure precise, consistent cartridge assembly every time you pull the handle. Whether you're fine-tuning loads for a hunting rifle or working up match rounds at the range, this die gives you the control to dial in exactly the seating depth you need.
The heart of this die is its laser-engraved micrometer thimble, graduated in increments of 0.001 inch, so adjustments are straightforward and repeatable. A floating bullet guide keeps the case and bullet in perfect vertical alignment as the seating stem does its work, which Lee's testing shows results in cartridges with minimal bullet runout. That precision matters: runout affects consistency, and consistency drives accuracy. The seating stem itself is machined and burnished to handle virtually any bullet profile without marring or deformation.
One of Lee's distinctive features here is the reversible bullet guide. Unthread it and reinstall it in the opposite orientation to use the die for simultaneous seating and crimping—a time-saver on progressive presses and a capability you won't find in every competing die at this price point. It's the kind of practical engineering that makes reloading faster and your ammunition more uniform.

Frequently Asked Questions
What is dead-length seating and why does it matter?
Dead-length seating means the die body rests on the shell holder as you seat the bullet. This creates a mechanical reference point that ensures your seating depth is uniform from one cartridge to the next. Uniform seating depth helps keep bullet runout minimal and contributes to consistent ballistics.
Can this die handle different bullet types and profiles?
Yes. The seating stem is machined and burnished specifically to seat a wide range of bullet point styles—from round nose to spire point to hollow point—without marking or deforming them.
Does the reversible bullet guide mean I can seat and crimp at the same time?
When you unthread the bullet guide and reinstall it in the opposite orientation, the die can perform seating and crimping in a single stroke. This is an exclusive Lee feature and is particularly useful if you're reloading on a progressive press and want to save a station.
How do I read and adjust the micrometer?
The micrometer thimble and die body are laser-engraved with a scale graduated in 0.001-inch increments, reading just like a precision depth micrometer. Adjustment is infinitely fine, so you can dial in any seating depth your load demands.
