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.
