The Redding 38387 Type S Match Bushing Neck Sizing Die Set is a precision three-die handloading kit engineered specifically for the .224 Valkyrie cartridge. Designed to minimise bullet runout and extend case life, the set includes a Type S Bushing Neck Sizing Die (Part #71387), a Body Die (Part #75387), and a Competition Bullet Seating Die (Part #55387). Handloaders can control neck tension precisely using interchangeable sizing bushings without working the entire case neck, while the Competition Seating Die aligns the projectile and cartridge case before seating via a micrometer adjustable in .001" increments.

Key Features:

• Precise Neck Sizing: The Type S Bushing Neck Sizing Die utilises interchangeable bushings (sold separately in .001" increments) to size case necks without overworking the brass.
• Independent Body Sizing: The included Body Die bumps the case shoulder and resizes the case body without contacting the neck, restoring fire-formed brass to proper chambering dimensions.
• Competition Alignment: The Competition Bullet Seating Die features an internal sliding sleeve that aligns the cartridge and projectile prior to seating, controlled by a top-mounted .001" micrometer.
• Universal Press Mounting: Standard 7/8"-14 threading ensures compatibility across standard single-stage and turret reloading presses.

Specifications:

• Calibre Compatibility: .224 Valkyrie (.224" / 5.7mm bullet diameter)

Who is the Redding Type S Match Bushing Neck Die Set for .224 Valkyrie for?

• Precision Rifle Competitors Loading .224 Valkyrie — requires minimal runout and uniform overall length for match ammunition, which this Type S match bushing neck sizing die set achieves using a sliding alignment sleeve and a .001" micrometer adjustment on the seating die.
• Long-Range Varmint Hunters Loading .224 Valkyrie — needs repeatable neck tension and extended brass life across high-volume firing cycles, using the 7/8"-14 thread Type S bushing neck die to work case brass minimally.

Less suitable for: Handloaders running alternative .224-calibre cartridges such as .223 Remington or .22 Nosler, as this tooling is strictly tailored to the SAAMI .224 Valkyrie chamber profile; shooters loading for these chamberings require a calibre-specific full-length or neck die set. Additionally, when cases become difficult to chamber after repeated firings, handloaders must utilise the included Body Die or switch to a dedicated full-length sizing die set.
