The Redding 338 Win Mag Premium Series Deluxe Die Set (Model 68163) is a precision 3-die metallic cartridge reloading set engineered for .338 Winchester Magnum ammunition. Machined from heat-treated alloy steel in the USA, this set includes a full-length sizing die with an integrated decapping assembly, a neck sizing die for fire-formed brass, and a standard seating die equipped with a Bullet Seating Micrometer head. The full-length sizing die incorporates a free-floating carbide size/expander button to minimise neck drag and brass stretching without inside-neck lubrication.

Key Features

  • Bullet Seating Micrometer: Features direct 0.001" graduated markings on the seating die stem to enable exact seating depth and jump-to-lands adjustments.
  • Free-Floating Carbide Expander Button: Reduces internal case neck friction during full-length sizing, improving neck concentricity and extending brass case life.

  • Heat-Treated Alloy Steel Construction: Delivers long-term dimensional stability and wear resistance under continuous reloading cycles.
