Perfect alignment. Predictable results. The ultra micrometer seater die uses a non-crimping design (except .30-30 Cal) and aligns case and bullet flawlessly. Its micrometer stem lets you tweak bullet depth until it's dialed in to your exact need.

• 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
