The Redding Type S – Bushing Neck Die Set (Manufacturer Model Number: 78415) is a precision three-die system engineered for reloading 6.5mm/284 Winchester and 6.5-284 Norma cartridges using 0.264" diameter projectiles. Designed for single-chamber bolt-action target rifles, this mechanical tool resizes cartridge case necks and seats bullets while maintaining fire-formed case body dimensions to maximise concentricity and brass working life. The dies feature standard 7/8"-14 industry threading, providing direct compatibility with standard Australian reloading presses.

Key Features:

• Precise Neck Tension Control: The Type S Bushing Neck Die utilises interchangeable steel or titanium-nitride bushings (available separately in 0.001" increments) to size case necks without excessive cold-working.
• Self-Centering Bushing Alignment: The sizing bushing is free-floating within the die body, allowing it to self-align with the cartridge neck to reduce bullet runout.
• Modular Decapping Assembly: Includes both an expander button and a dedicated decapping pin retainer for reloaders sizing uniform, neck-turned brass without an internal expander.
• Dedicated Body Die: Features an included body die designed to bump the cartridge shoulder and restore chamber clearance without contacting or altering the neck.
• Series 92000 Seating Die: Ships with a standard bullet seating die for repeatable, in-line bullet placement.

Specifications:

• Cartridge Compatibility: 6.5-284 Winchester / 6.5-284 Norma (0.264" diameter projectiles)
• Die Thread Interface: Standard 7/8"-14 threading
• Set Configuration: 3-Die Set (Type S Bushing Neck Sizing Die, Body Die, Standard Bullet Seating Die)
• Shellholder Compatibility: Redding #1 shellholder (sold separately)
• Operating Mode: Fully manual/mechanical reloading tool

Who is the Redding 6.5/284 Winchester Type S - Neck Die Set for?

• F-Class and benchrest precision competitors — relies on standard 7/8"-14 industry threading to run on standard precision presses while manipulating neck tension in 0.001" increments using interchangeable bushings to minimise runout on fire-formed 6.5-284 Winchester brass.
• Long-range handloaders tuning bolt-action rifles — matches fire-formed cases to a single bolt-action chamber using standard 7/8"-14 threading and a Redding #1 shellholder, isolating shoulder bump via the dedicated body die without overworking the 0.264" bullet interface.

Less suitable for: Semi-automatic rifles where neck-sized ammunition can cause chambering and extraction failures; these actions require a Type S full-length bushing die set that resizes the entire cartridge body down to minimum factory specifications.
