The Redding 7mm Rem Mag Type S - Match Neck Die Set (MPN 38136) is a precision three-die reloading system engineered to resize cartridge brass and seat bullets for 7mm Remington Magnum (.284 in bullet diameter) ammunition. Built with standard 7/8"-14 reloading press threading, this manual bench-mounted set provides handloaders with precise control over neck tension, shoulder bump, and overall cartridge length without overworking the brass.

Key Features

• Three-Die Configuration: Includes a Type S Bushing Neck Sizing Die (Part #71136), a dedicated Body Die (Part #75136), and a Competition Bullet Seating Die (Part #55136).
• Interchangeable Bushing Sizing: Allows handloaders to adjust neck tension in precise 0.001″ increments using interchangeable neck bushings (sold separately), preventing excessive brass fatigue.
• Decapping Pin Retainer: Enables neck sizing without utilizing the expander button for reloaders using turned necks or sorted brass with uniform wall thickness.
• Dedicated Body Die: Bumps the cartridge shoulder and resizes the case body without contacting or working the case neck.
• Micrometer Competition Seating: Features an internal alignment sleeve that supports the case prior to bullet seating, paired with a micrometer seating stem calibrated in 0.001″ increments for repeatable seating depth and minimal bullet runout.
• Universal Press Fit: Mounts directly into standard single-stage and progressive reloading presses using industry-standard 7/8"-14 threads.

Who is the Redding 7mm Rem Mag Type S - Match Neck Die Set for?

• Precision long-range target shooters using bolt-action rifles — requires minimal bullet runout and exact cartridge dimensions for 7mm Remington Magnum ammunition, which this 7mm Rem Mag reloading die set delivers via an internal alignment sleeve and a seating stem adjustable in 0.001″ increments.
• Handloaders seeking maximum brass life — relies on working fire-formed brass minimally by adjusting neck sizing in 0.001″ bushing increments and using a separate body die on standard 7/8"-14 press threads to bump shoulders only when chambering resistance occurs.

Less suitable for: Handloaders loading for multiple rifles, semi-automatic rifles, or rough-and-ready hunting environments where 100% chambering and feeding reliability takes precedence over maximum brass life; a full-length sizing die set or Type S full-length sizing set fits these applications better.
