The Redding 284 Winchester Type S - Full Length Die (MPN 77141) is a precision handloading tool designed to size the complete case body, reset shoulder headspace, and control neck tension on .284 Winchester brass. Built with industry-standard 7/8"-14 threads, it fits standard single-stage and progressive mechanical reloading presses. By using self-centering, interchangeable neck sizing bushings (sold separately), this Type S die prevents excessive working of the case neck brass, maintaining neck concentricity and prolonging case life while ensuring reliable chambering.

Key Features

• Full-Length Sizing with Bushing Neck Control: Resizes case body dimensions and bumps shoulders to SAAMI specifications while utilising a floating neck bushing to size necks without overworking brass.
• Dual Configuration Decapping Rod: Supplied with a standard expander button as well as a decapping pin retainer for shooters who turn case necks and size without an expander ball.
• Convertible Body Die Utility: Removing the internal neck sizing bushing allows the tool to function strictly as a body die for shoulder bumping and body sizing without working the neck.
• Adjustable Decapping Assembly: Permits partial neck sizing along the length of the case neck depending on handloader preference.
• Standard Press Integration: Features standard 7/8"-14 external threading to integrate with standard mechanical reloading presses.

Who is the Redding 284 Winchester Type S - Full Length Die for?

• F-Class Open Competitive Shooters — Delivers exact shoulder bump and tight concentricity for .284 Winchester match brass using standard 7/8"-14 thread presses to ensure smooth chambering across high-volume strings of fire.
• Long-Range Target Handloaders — Provides precise control over neck tension increments down to 0.001" on .284 Winchester cartridge cases using interchangeable bushings to minimise projectile runout.
• Precision Handloaders Seeking Low Runout Tolerances — Features a self-centering, floating bushing design that resizes .284 Winchester case necks on 7/8"-14 presses without inducing neck-to-body misalignment.

Less suitable for: Handloaders loading derivative cartridges like 6.5-284 Norma or 6mm-284 without neck-specific tooling, or shooters looking for an all-in-one out-of-the-box die without purchasing dedicated sizing bushings separately; standard fixed-dimension full-length sizing dies or calibre-dedicated neck dies fit those applications better. Case lubrication is required prior to operation to avoid stuck cases.
