The Ultra™ Micrometer Seater Die is a non-crimping style seater die that holds the bullet and case in perfect alignment while the bullet is press-fit seated. A handy micrometer adjusts the bullet seating depth to 0.001" or even finer increments.
A close-fitting, sliding Die Chamber holds the bullet and case for their entire length, as well as holds the bullet, case and Bullet Seating Stem in a common axis during the bullet seating operation to ensure match-grade alignment. The sliding Die Chamber has a concentric bullet channel that is just slightly larger (per side) than the bullet diameter. This tight fit ensures straight line (co-axial) seating. The Bullet Seating Stem contacts the bullet ogive as far away from the bullet's tip as possible.
Ultra™ Micrometer Features

• Includes all the popular straight line seating features of our original Bench Rest®  Seater Die plus an ultra accurate micrometer for adjusting bullet seating depth.
• Micrometer allows fine adjustments in either direction, easily adjustable to .0005". Index marks at increments of .001" are clearly marked.
• After you have seated your bullet close to the desired depth and measured it, simply adjust the micrometer stem down to the desired depth and the cartridge will be exactly the length you need. Fine-tuning of your rounds to bring them out close to the lands of your rifling is simple.
• Eliminates much of the trial and error that was once associated with seating accurate rounds.
• Bright, white markings make micrometer easy to read.
