The Redding Type S Match Bushing Neck Die Set for 6mm Remington BR (MPN: 38317) is a precision 3-die workshop set engineered to control neck tension, cartridge concentricity, and seating depth for fire-formed cartridge cases. Designed around industry-standard 7/8"-14 TPI threads, this set accommodates bolt-action reloading presses to support competition-grade .243" diameter projectile loading. By isolating neck sizing, body bumping, and projectile seating into dedicated steps, the set minimises brass fatigue and bullet runout.

Key Features:

• Type S Bushing Neck Sizing Die: Utilises interchangeable, self-centring bushings to size case necks in precise increments without overworking brass. Includes an adjustable decapping assembly, an expander button, and a decapping pin retainer for sizing without an internal expander.
• Dedicated Body Die: Restores critical case body dimensions and bumps the shoulder without contacting the case neck, preserving fire-formed dimensions until chambering resistance occurs.
• Competition Seating Die: Integrates a free-floating, spring-loaded case alignment sleeve that centres the bullet and case before seating, controlled by a non-clicking micrometer calibrated in 0.001" increments.
• Thread Compatibility: Machined with 7/8"-14 TPI mounting threads to fit standard reloading presses.

Who is the Redding Type S Match Bushing Neck Die Set for 6mm Remington BR for?

• Benchrest competition shooters reloading for bolt-action rifles — requires precise bullet alignment and fire-formed brass preservation, which this 6mm Remington BR neck die set delivers through its self-centring neck bushing system and micrometer seating head adjustable to 0.001" increments.
• F-Class and precision rifle series competitors — relies on uniform projectile release and low runout across repeated firings, supported by this 6mm Remington BR neck die set using a full-capture alignment sleeve and body die on standard 7/8"-14 TPI presses.
• Long-range varmint hunters seeking extreme cartridge concentricity — demands minimal bullet runout on target-dimensioned chambers, achieved using this 6mm Remington BR neck die set's dedicated seating micrometer with direct 0.001" graduations.

Less suitable for: Standard-length 6mm Remington cases or semi-automatic actions that require full-length case sizing every firing cycle; these applications require a standard full-length sizing die or small-base die set.
