Lee Precision Deluxe 4-Die Set 40 S&W / 10mm Carbide

The Lee Precision Deluxe 4-Die Set (MPN 90965) is a complete carbide reloading solution for handloaders working with 40 S&W and 10mm Auto. Built around Lee's pistol Deluxe 4-Die configuration, the set combines three carbide dies with a micrometer-adjustable bullet seating die to cover every stage of the reloading cycle without the need for case lubrication during sizing.

The set includes a carbide full-length sizing die with integral decapping unit, a carbide powder-through expanding die for belling the case mouth and powder drop, a micrometer bullet seating die for precise seating-depth adjustment, and a dedicated carbide factory crimp die that applies a consistent, squared crimp for reliable feeding. A universal shell holder ships with the set and fits the most common reloading presses.

For best results, trim cases to between .840 and .850 inches prior to resizing. When switching from 40 S&W to 10mm Auto on the same die set, Lee recommends backing the powder-through expanding die and bullet seating die out two full turns and using large pistol primers. The Deluxe 4-Die Set delivers full pistol reloading functionality in a single, ready-to-use package.
