The Forster Products Ultra Micrometer Seater Die for 300 Win Mag is a precision reloading die built for handloaders who demand repeatable, match-grade ammunition. If you're serious about rifle reloading—whether you're chasing tight groups at the range, preparing hunting loads, or working up precision rounds—this micrometer seater die gives you the fine control to dial in bullet seating depth to exacting tolerances and reproduce those settings shot after shot.
What sets the Forster Ultra Micrometer Seater apart is its micrometer adjustment mechanism, which lets you fine-tune bullet seating depth in increments as small as .0005 inch to .001 inch. That level of precision matters when you're optimizing bullet-to-lands clearance or chasing consistency across a batch. Once you've found your ideal seating depth, simply record the micrometer setting and dial back to it whenever you load the same bullet—no guesswork, no trial and error. Switching between different projectile weights and profiles becomes straightforward and repeatable.
Like all Forster dies, this seater is machined from quality steel to tight tolerances, hand-polished before and after heat treatment for a refined finish, and equipped with Forster's Cross Bolt Die Locking Ring. That locking ring design tightens both ends of the split collar rather than threading a screw directly into the die itself, protecting the die threads and ensuring solid, repeatable hold.

This Forster Ultra Micrometer Seater Die is sized for 300 Win Mag ammunition.
The micrometer adjustment allows seating depth changes in increments of .0005 to .001 inch, giving you the precision needed for tuning rounds to your rifle's individual chamber and lands.
Yes. The micrometer allows you to easily switch between different bullet profiles and weights. Simply dial the micrometer to your recorded seating depth for each bullet type, making load development and ammunition swaps straightforward.
Instead of tightening a screw directly into the die's threads, the Cross Bolt Ring tightens both ends of the split collar, distributing pressure more evenly and protecting the die threads from wear and damage.
