Lyman's new Deluxe 3-Die Sets give reloaders all the options they need to enhance the accuracy of their reloads and extend the life of their brass. By adding both a premium Carbide Expander Assembly and a Neck Sizing Die, Lyman has created two die sets in one. Neck sizing eliminates over-working the brass, dramatically extending case life. Set includes: Deluxe Carbide Expander Assembly, Neck Sizing Die, Standard Full Length Sizing Die, and a Standard Bullet Seating Die.
