The Redding Master Hunter Deluxe 3-Die Set for .338 Winchester Magnum (SKU: 29163) provides precision handloaders with the tools required to produce consistent, match-grade hunting ammunition. Machined to standard 7/8"-14 threads, this mechanical three-die set is compatible with major reloading presses across Australia and includes a Full-Length Sizing Die with a free-floating carbide size button, a standard Neck Sizing Die, and a Competition Seating Die with an integrated micrometer adjustment head.

Key Features

• Competition Seating Die: Features a patented internal bullet guide and sliding alignment sleeve that fully supports the cartridge case prior to seating, maintaining straight bullet-to-case concentricity.
• Micrometer Seating Depth Control: Equipped with an engraved micrometer top calibrated in 0.001" increments, allowing exact and repeatable adjustments for overall cartridge length and seating depth.
• Carbide Sizing Button: The full-length sizing die incorporates a free-floating carbide expander button that reduces friction and neck stretch on the upstroke without requiring inside-neck lubrication.
• Dual Sizing Capabilities: Includes a dedicated Neck Sizing Die to preserve fire-formed brass dimensions for bolt-action rifles, alongside a Full-Length Sizing Die for smooth feeding in demanding hunting environments.
• Standard Press Interface: Machined with industry-standard 7/8"-14 thread pitch to fit single-stage and turret reloading presses.

Who is the Redding 338 Win Mag Master Hunter Deluxe Die Set for?

• Big-game hunters handloading 338 Winchester Magnum — who require full-length sizing and seamless chambering in field conditions using standard 7/8"-14 thread pitch reloading presses, combined with the brass longevity of an included neck-sizing die for range practice.
• Long-range shooters developing match-grade 338 Winchester Magnum loads — who depend on the 338 Win Mag reloading die set to eliminate bullet runout and make precise seating depth corrections calibrated directly in 0.001" increments.

Less suitable for: Cartridges outside the standard SAAMI .338 Winchester Magnum case dimensions, such as .338 Lapua Magnum or .338 RUM, which require calibre-specific magnum die sets, or benchrest applications requiring dedicated neck bushing dies for exact thousandths-of-an-inch neck tension management.
