Lee Precision 308 Winchester Micrometer Bullet Seating Die
The Lee Precision Micrometer Bullet Seating Die is designed specifically for .308 Winchester (7.62 NATO) cartridges. It ensures consistent bullet seating depth through a body that contacts the shell holder for uniform pressure distribution.
The easy-adjust micrometer mechanism allows precise depth setting and quick return to previously set positions. A floating bullet guide maintains alignment between the case mouth and bullet, reducing run-out during seating.
The precision threaded seating stem seats bullets without marking them, preserving bullet integrity. The die can also be converted to perform both seating and crimping in a single operation.

This die is very accurate and easy to use. I set the depth precisely and the bullet sits evenly without any marks. The floating guide makes a noticeable difference in consistency. I’ve used it for several batches and the results are reliable.

Great precision for .308 loads. The micrometer adjustment is smooth and the seating depth is consistent. I appreciate the option to crimp in one step. No marking on bullets, which is a big plus.

Works well for seating bullets. The floating guide helps keep alignment, and the depth control is accurate. A bit more effort to convert to crimp mode, but it’s manageable.
