The Redding 284 Winchester Type S - Match Full Die Set (MPN 36141) is a precision 2-die reloading system engineered specifically for standard .284 Winchester cartridge cases. Constructed from precision-machined, case-hardened steel, the set pairs a Type S - Bushing Full-Length Sizing Die with a Competition Bullet Seating Die. Built with standard 7/8"-14 TPI threading, these dies mount into standard single-stage, turret, and progressive reloading presses to deliver exact neck tension control and minimal bullet runout for competition-grade handloading.

Key Features

• Interchangeable Bushing Sizing: The Type S full-length sizing die accepts self-centering neck sizing bushings (sold separately) adjustable in 0.001" increments, allowing exact neck tension management without overworking brass necks.
• Configurable Expander Assembly: Includes both an expander ball and a decapping pin retainer, enabling reloaders to remove the expander button entirely when sizing uniform neck-turned cases to reduce brass stretch.
• Competition Seating Die: Features an internal sliding alignment sleeve that fully captures and aligns both the cartridge case and the 0.284" diameter bullet prior to seating.
• Micrometer Depth Adjustment: The seating die features a calibrated micrometer head marked in 0.001" increments for precise, repeatable bullet seating depth and jump tuning.

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

• Long-range target shooters using the 284 Winchester cartridge — requires full-length case resizing alongside a sliding-sleeve seating mechanism to minimise concentricity runout on .284 Winchester brass across standard 7/8"-14 TPI competition reloading presses.
• Handloaders demanding micrometer seating depth adjustments and interchangeable neck sizing bushings — provides precise bullet jump tuning via a calibrated seating head marked in 0.001" increments combined with full-length sizing control using interchangeable bushings stepped in 0.001" increments.

Less suitable for: Handloaders shooting .284-based wildcat cartridges such as 6.5-284 Norma, 6mm-284, or .284 Shehane, which require dedicated wildcat-specific die sets, or general hunters seeking simpler setups without neck-bushing management, who are better served by standard non-bushing full-length 2-die sets.
