A Lyman innovation for extending case life.

By adding both a premium Carbide Expander Assembly and a Neck Sizing Die, Lyman has created two die sets in one. Neck sizing eliminates overworking the brass, extending case life. Set includes:

Deluxe Carbide Expander Assembly, with a free floating carbide sizing button, which smooths neck expansion by moving the button up the decapping rod to better use the press' leverage. It eliminates the need for inside neck lube.

Neck Sizing Die, which allows the case to retain the precise chamber dimensions of the individual rifle while avoiding excessive working of the brass. Size only where/when needed with the Deluxe Rifle 3 Die Sets & Neck Expanding Die to tailor your reloads for the best accuracy and reliability.

Standard Full Length Sizing Die, for taking brass down to factory dimensions.
