The Redding Type S Match Bushing Neck 3-Die Set (Model 38280) is engineered for precision handloading of the 7mm Remington Short Action Ultra Magnum (7mm Rem SAUM) cartridge. Built with standard 7/8"-14 threads, this three-die set is designed for manual reloading presses to optimise neck tension, control concentricity, and minimise brass fatigue on fire-formed cases firing .284 in (7.21 mm) diameter projectiles.

Key Features

• Three-Piece Match Configuration: Includes a Type S Bushing Neck Sizing Die, a dedicated Body Die, and a Competition Bullet Seating Die.
• Interchangeable Bushing System: The neck die accepts Redding self-centring bushings (available separately in 0.001" increments), allowing precise neck tension adjustment without overworking the brass.
• Configurable Decapping Assembly: Features an adjustable decapping rod with an interchangeable size button and decapping pin retainer to allow sizing with or without an internal expander ball.
• Dedicated Body Sizing: The included Body Die bumps the case shoulder and resizes the case body dimensions without touching the neck.
• Micrometer Seating Die: Features an internal sliding alignment sleeve that fully supports the cartridge case prior to seating, combined with a micrometer head calibrated in 0.001" increments for precise seating depth adjustment.

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

• Long-Range Precision Rifle Shooters — Requires precise bullet seating control and minimal case neck runout for 7mm Remington SAUM handloads, utilising a micrometer seating head calibrated in 0.001" increments on standard 7/8"-14 threaded reloading presses.
• Benchrest and F-Class Competitors — Controls brass work-hardening and neck tension on fire-formed cases by using interchangeable sizing bushings graduated in 0.001" steps alongside a sliding-sleeve seating die to maximise concentricity for .284 in (7.21 mm) diameter projectiles.

Less suitable for: Firearm platforms chambered in alternative short magnums such as 7mm WSM or 6.5 SAUM, or semi-automatic rifles that require guaranteed full-length chambering every cycle; these applications are better served by full-length sizing dies or full-length bushing die sets.
