The Lyman Pro Micrometer Seating Die for .308 is built for reloaders who need repeatable, precise bullet seating depth. This .308 rifle reloading die puts bullet seating adjustment at your fingertips—literally. Instead of fussing with trial-and-error adjustments or complex setup procedures, you dial in your exact seating depth on the integrated micrometer head, then lock it in. That means you can return to the same seating depth shot after shot, or make fine adjustments in small increments when you're experimenting with load development.
The seating punch is designed to float and center the bullet in the case, which minimizes run-out (bullet tilt) and keeps your ammunition as straight and concentric as your reloading bench technique allows. Less run-out translates to tighter groups and more consistent velocities downrange—exactly what long-range and precision rifle shooters are after. The die is machined from stainless steel, so it resists corrosion and holds up through years of regular use without requiring the fussy maintenance or protection that mild steel dies demand.
Whether you're working up loads for a hunting rifle, a competition gun, or a precision target setup, the micrometer seating die cuts out guesswork and lets you focus on load development itself. It's the kind of tooling that pays for itself in consistency and saved ammunition during the testing phase.

This is a .308 seating die, designed for reloading .308 Winchester and related .308 cartridges.
The micrometer head lets you adjust bullet seating depth by turning a dial. You dial in your desired seating depth, and the micrometer allows fine adjustments in small increments. Once set, you can return to that exact depth for consistent bullet seating across your ammunition batches.
The floating punch centers the bullet in the case as it's being seated, which minimizes bullet run-out (the angle of the bullet relative to the case axis). Less run-out produces more concentric ammunition and more consistent ballistics.
The stainless steel construction resists rust and corrosion, so it doesn't require the same level of maintenance or protection that standard steel dies do. It will maintain its finish and function through regular use.
