The ultra micrometer seater die is a non-crimping style seater die, with the exception of the 30-30 model, designed to maintain precise alignment between the bullet and case during the press-fit seating process. It features a convenient micrometer that allows for precise adjustment of bullet seating depth according to user specifications. Once the bullet is seated close to the desired depth and measured, the micrometer stem can be adjusted up or down to achieve the exact cartridge length required.

• Incorporates all the well-known features of the original bench rest seater die for straight-line seating, along with an ultra-precise micrometer for adjusting bullet seating depth
• The micrometer facilitates precise bidirectional adjustments, offering seamless calibration to an accuracy of 0.0005 inches
• Graduations at increments of 0.001 are clearly marked
• Reduces the trial and error previously associated with achieving precise round seating
• The micrometer features bright, white markings that enhance readability
