The Redding Type S Match Bushing Neck Die Set for .243 Winchester (MPN: 38114) is a precision 3-die handloading system engineered to provide exacting control over case neck tension, headspace, and concentricity. Designed for standard 7/8"-14 threaded reloading presses, this mechanical steel die set processes brass fired from bolt-action chambers to minimise work-hardening while maximising case life and bullet alignment. The set includes a Type S Bushing Neck Sizing Die, a dedicated Body Die, and a Competition Bullet Seating Die housed in a durable plastic storage case, with a packaged shipping weight of approximately 0.7–0.8 kg.

Key Features

• Type S Bushing Neck Sizing Die: Accepts interchangeable sizing bushings available in 0.001" diameter increments (sold separately) to precisely set external neck tension without excessive working of the brass. Features an adjustable decapping rod for partial neck sizing and includes both a standard expander button and a decapping pin retainer.
• Dedicated Redding Body Die: Full-length resizes the case body and bumps the shoulder (typically 0.001"–0.002" for match chambers or 0.002"–0.003" for field use) to maintain correct headspace without contacting or altering the case neck.
• Competition Bullet Seating Die: Utilises an internal sliding alignment sleeve that captures the case before bullet seating begins, paired with a micrometer-adjustable seating stem calibrated in 0.001" increments for straight bullet alignment and minimal runout.
• Press Compatibility: Built with standard 7/8"-14 threads to interface directly with common single-stage and turret reloading presses. Compatible with standard Redding Shellholder #1 (Part #11001) or Competition Shellholder #11601.

Who is the Redding 38114 Type S Match Neck Die Set for .243 Winchester for?

• Precision Target Shooters — Requires precise neck tension management for .243 Winchester bolt-action rifles, utilizing interchangeable bushings in 0.001" increments to size fired case necks without overworking the brass.
• Benchrest Handloaders — Demands minimal bullet runout and exact depth consistency, achievable through this reloading neck die set's micrometer seating stem calibrated in 0.001" increments and an internal sliding sleeve.
• Varmint Hunters — Accurising fire-formed .243 Winchester cases across repeated firings by using the dedicated body die to bump shoulders back 0.002"–0.003" without altering neck dimensions.

Less suitable for: Semi-automatic, lever-action, or pump-action rifles requiring guaranteed feeding and chambering, where a full-length sizing die set is required instead of a neck-sizing die set.
