The Redding Master Hunter Deluxe (MH-C) 3-Die Set for 7mm Remington Magnum (Part #29136) is a precision reloading system engineered for workshop bench use. It delivers match-grade bullet seating accuracy alongside reliable case sizing for hunting ammunition. Built with industry-standard 7/8"-14 threading, the set mounts to standard single-stage and turret reloading presses. It provides a complete three-die configuration containing a full-length sizing die equipped with a free-floating carbide expander button, a dedicated standard neck sizing die, and a competition seating die featuring a micrometer adjustment head graduated in 0.001" increments.

Key Features

• Full-Length Sizing with Carbide Button: Restores fired 7mm Remington Magnum brass to factory cartridge dimensions while the free-floating carbide expander ball reduces internal neck friction without requiring inside-neck lubrication.
• Competition Micrometer Seating Die: Uses an internal sliding alignment sleeve to guide both the cartridge case and .284-inch projectile in alignment before seating, with a micrometer head calibrated in 0.001" graduations for exact seating depth control.
• Dedicated Neck Sizing Die: Enables sizing of fire-formed brass necks only, preserving custom fire-formed case capacity for load testing.
• Standard Press Compatibility: Threaded in standard 7/8"-14 TPI to integrate with standard mechanical reloading presses.

Who is the Redding 7mm Rem Mag Master Hunter Deluxe Die Set for?

• 7mm Remington Magnum hunters — requires full-length resized brass for chambering reliability in field conditions alongside a competition seating die with 0.001" micrometer increments to assemble precision hunting ammunition on standard 7/8"-14 presses using a Redding #6 shellholder.
• Handloaders developing precision loads — provides dual-die versatility by including both a neck sizing die for fire-formed brass and a full-length sizing die with 7/8"-14 threading, allowing handloaders to switch sizing methods while adjusting bullet seating depths in precise 0.001" micrometer graduations.

Less suitable for: Reloading non-magnum or alternate 7mm cartridges such as 7mm PRC, 7mm-08 Rem, 7mm WSM, or .280 Ackley Improved; handloaders working with those calibres require dedicated caliber-specific die sets matching their exact chamber dimensions.
