The Redding 308 Win Type S - Match Neck Die Set (MPN 38155) is a three-die mechanical reloading system engineered for sizing .308 Winchester (7.62x51mm) brass and seating projectiles with minimal runout. Built on industry-standard 7/8"-14 threaded die bodies, this set uses interchangeable sizing bushings to regulate neck tension without over-working the brass case neck. The set combines a Type S Bushing Neck Sizing Die, an independent Body Die for bumping case shoulders, and a Competition Bullet Seating Die featuring an internal sliding alignment sleeve and a micrometer graduated in 0.001″ increments for precise seating depth management.

Key Features

• Interchangeable Bushing System: The Type S Bushing Neck Sizing Die uses self-centering bushings (available separately in 0.001″ increments) to set exact neck tension and allow sizing of the full neck or a partial neck length.
• Decapping Pin Retainer: Includes a decapping rod with standard size button as well as a decapping pin retainer to allow neck sizing without an internal expander ball when using uniform brass.
• Dedicated Body Sizing: Includes an independent Body Die designed to resize the case body and bump the shoulder back to specification without altering case neck dimensions.
• Competition Seating Alignment: The Competition Bullet Seating Die captures both the bullet and the cartridge case in a tight-tolerance sliding sleeve before seating starts to maintain concentricity.
• Micrometer Adjustments: Built with a top-mounted micrometer head graduated in 0.001″ increments to deliver repeatable projectile seating depth adjustments.
• Universal Press Mounting: Uses standard 7/8"-14 threads to interface with standard single-stage and turret reloading presses.

Who is the Redding 308 Win Type S - Match Neck Die Set for?

• Long-range precision bolt-action shooters — relies on standard 7/8"-14 threaded die bodies and the Competition Seating Die with 0.001″ micrometer adjustments to achieve match-grade concentricity and near-zero runout when reloading fire-formed .308 Winchester cases.
• F-Class and Benchrest target competitors — utilises interchangeable neck bushings adjustable in 0.001″ increments within this 308 Winchester reloading die set to precisely calibrate bullet release tension and extend brass life over repeated firings.
• Precision deer and pest hunters handloading bespoke ammunition — uses the dedicated Body Die and neck sizing die configured for .308 Winchester (7.62x51mm) to bump case shoulders and restore chambering clearance without over-working brass necks.

Less suitable for: High-volume semi-automatic platforms or handloaders running mixed cases across multiple different rifles; these conditions require a standard full-length sizing die or small base sizing die to guarantee reliable feeding and chambering rather than neck-sizing dies.
