Featuring a Carbide Size Button in the full length sizing die and the Bullet Seating Micrometer on the seating die. Following the introduction of Bullet Seating Micrometers for Redding's standard series of seating dies, Redding's customers have been asking for complete die sets with this added precision. Redding have now added two popular upgrades to a select group of "Series A" dies to create the new "Premium" Series Die Sets. The upgrades include combining a Carbide Size Button in the full length sizing die and the Bullet Seating Micrometer on the seating die. The "Premium" Deluxe, three (3) die set; contains the "Premium" two (2) die set (described above) with the addition of a standard Series A neck sizing die.
