The Redding 78317 Type S Bushing Neck Die Set is a 3-die precision reloading kit engineered for 6mm B.R. Remington and 6mm Norma BR cartridges. Designed for bolt-action precision shooting, this set provides precise control over case neck tension while minimising brass working to extend case life. The 3-piece set includes a Type S Bushing Neck Sizing Die (Die #71317), a dedicated Body Die (Die #75317) to bump shoulders and restore case body dimensions without touching the neck, and a Series 92000 Standard Bullet Seating Die with a built-in crimp ring. Each die uses industry-standard 7/8"-14 threading for direct compatibility with standard Australian and international reloading presses.

Key Features

• Interchangeable Sizing Bushings: Utilises self-centering neck bushings (available separately in 0.001 in increments) to precisely adjust neck tension without overworking brass.
• Dual Decapping Configuration: Includes both a standard expander button for non-turned case necks and a decapping pin retainer for turned necks requiring outside-only sizing without expander drag.
• Dedicated Case Body Die: Resizes the case body diameter and sets back the shoulder position independently, preserving neck concentricity when full-length brass restoration is needed.
• Adjustable Decapping Rod: Allows reloaders to set the die for partial or full-length neck sizing based on chamber requirements.
• Standard Seating Die: Features a Series 92000 seating assembly configured for seating 0.243 in / 6mm diameter bullets with an integrated crimping ring.

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

• Precision benchrest shooters — Requires precise neck tension adjustment using bushings calibrated in 0.001 in increments to minimise runout and brass fatigue on fire-formed 6mm BR cartridge cases.
• F-Class competitors — Relies on a dedicated 6mm BR neck bushing die set with an interchangeable decapping retainer and standard 7/8"-14 thread interface to size turned-neck brass without internal expander drag.
• Long-range target reloaders — Uses the separate body die and neck sizing assembly to maintain shoulder headspace and seat 0.243 in / 6mm bullets to uniform depths.

Less suitable for: Reloading for semi-automatic actions or loose-chambered hunting rifles requiring continuous full-length resizing, where a standard full-length sizing die set or small base die set is required for reliable feeding; or for precision reloaders requiring micrometer seating adjustments down to 0.001 in, who require a competition match bushing die set with a micrometer seating die.
