Following the introduction of Bullet Seating Micrometers for Redding's conventional dies, Redding created the "Premium Die Set" featuring a Carbide Size Button in the Full Length sizing die and a Bullet Seating Micrometer on the seating die. The Premium Deluxe Die Sets contains a Full Length Sizing Die with Carbide Size Button, a Neck Sizing Die, and a conventional Bullet Seating Die with a Bullet Seating Micrometer. The Full Length Die and conventional Seating Die can be used to reload ammunition for multiple rifles chambered for the same cartridge with proper adjustment. If reloading for a bolt-action rifle, the cartridge cases may be neck sized only which may increase the accuracy potential of the ammunition being reloaded but may not chamber freely in other rifles. Redding Dies are carefully machined on precision lathes capable of holding the tightest tolerances in the industry and heat treated in atmospherically controlled furnaces for a lifetime of use.
