This is the NON SAAMI Spec die that is 0.014" longer than SAAMI Spec.
The Redding Competition Seating Die seating stem is precision ground to exactly match bullet diameter. Alignment and accuracy are enhanced by the cartridge case and bullet being completely supported and aligned in a close fitting, precision ground sleeve before the bullet seating begins. The micrometer is calibrated in .001" increments for precise seating depth and is infinitely adjustable. The micrometer also has a setting feature that allows you to set the micrometer to favorite seating depth. A VLD replacement seating stem is available at extra cost, and it purchased separately.
