The Ultra Micrometer Seater Dies includes the features of the original Bench Rest Seater Die. The Bench Rest Seater Dies was the first of its kind on the market. This is due to the bullet, cartridge case, and seating system are a fitting chamber for the seating operation. With the addition of the ultra-accurate micrometer, the die is able make accurate seating depth adjustments. The micrometer (index marks in 0.001” increments) allows fine adjustments to as small as 0 .0005". The ability to fine-tune with the twist of the micrometer side steps the frustration of trial and error. This die is packaged in a cardboard box.
