Forster Products Inc U00107 Ultra Micrometer Seater Die 308 Win

The Forster Products Ultra Micrometer Seater Die for .308 Winchester puts precision bullet seating within reach of any reloader willing to dial in their craft. Unlike standard seating dies that rely on press stroke or trial-and-error adjustment, this non-crimping die couples a precision micrometer with Forster's straight-line seating design to lock down cartridge length to your exact specifications. If you're loading match ammo, hunting rounds, or anything in between, repeatable seating depth is foundational to consistency—and this die makes it achievable without frustration.

The micrometer adjustment mechanism is the heart of the system. After seating a bullet to approximate depth, you measure the cartridge, then simply turn the micrometer stem up or down until the cartridge reaches your target length. Gradations are marked in .001" increments, with fine-tuning possible in .0005" steps, so dialing in your load is methodical rather than guesswork. The bright white markings on the micrometer face stay readable under typical reloading bench lighting, cutting down eye strain on long sessions.

Forster engineered this die to combine the best features of their Bench Rest Seater platform with micrometer control, so you get reliable, repeatable seating in both directions. Whether you're loading for precision rifle competition, long-range hunting, or target work, this die eliminates much of the back-and-forth that once came with achieving consistent cartridge length. It's a thoughtful tool for reloaders who understand that the small details—bullet seating depth among them—separate good ammo from great ammo.
