The Redding Master Hunter (MH-C) 2-Die Set for .300 Weatherby Magnum (SKU: 28252) provides precision handloaders with the tools needed to produce match-grade hunting ammunition. This two-die set pairs a full-length resizing die with a competition seating die to return fired brass to factory SAAMI dimensions while ensuring optimal cartridge alignment. Built to interface with standard reloading presses via industry-standard 7/8"-14 threading, the set ensures reliable chambering and minimal bullet runout for heavy-magnum field applications.

Key Features

• Full-Length Resizing Die: Restores fired brass to factory specifications, featuring a free-floating, polished carbide expander button that reduces neck friction and drag without requiring internal case neck lubrication.
• Competition Seating Die: Utilises an internal, tight-tolerance bullet-alignment sleeve that centres both the case neck and the 0.308-inch bullet before seating begins.
• Micrometer Adjustability: Integrated top micrometer allows for precise bullet seating depth adjustments calibrated in 0.001" increments for fine-tuning bullet jump.
• Standard Threading: Machined with standard 7/8"-14 threading to fit standard single-stage and progressive reloading presses.

Who is the Redding Master Hunter Die Set for .300 Weatherby Magnum for?

• Big-game hunters loading for .300 Weatherby Magnum — Requires full-length resizing alongside a free-floating carbide expander button on standard 7/8"-14 threading presses to guarantee flawless chamber feeding under high-stress hunting conditions.
• Extreme long-range hunters tuning bullet seating depth — Relies on the competition seating die's integrated micrometer adjustable in 0.001" increments to dial in precise bullet jump and achieve optimal external ballistics with heavy projectiles.
• Precision shooters requiring benchrest-grade bullet concentricity — Utilises the full-length seating sleeve tailored for 0.308-inch diameter bullets to maintain strict axial alignment and minimise runout on high-velocity magnum cartridges.

Less suitable for: Handloaders running alternate .30-calibre cartridges such as the .300 Winchester Magnum or .300 Winchester Short Magnum; distinct shoulder angles, radius belts, and case geometries make these cases incompatible, requiring a dedicated .300 Win Mag or .300 WSM 2-die set instead.
