The Redding Type S Bushing Neck Sizing 3-Die Set for .243 Winchester (MPN: 78114) is a precision handloading tool designed for exact case sizing, neck tension management, and bullet seating. Built for standard SAAMI-spec .243 Winchester brass using 0.243" diameter projectiles, this set incorporates an interchangeable bushing system that sizes case necks without overworking the brass. The 3-piece kit includes a Type S Bushing Neck Sizing Die, an independent Body Die for bumping the case shoulder, and a Series 92000 Standard Bullet Seating Die with a built-in crimp. All dies feature standard 7/8"-14 threads to mount securely in common single-stage and turret reloading presses.

Key Features

• Interchangeable Bushing System: Utilises freely floating Redding neck sizing bushings (sold separately, available in 0.001" increments) to allow exact neck tension adjustments while maintaining concentricity.
• Dual Decapping Configuration: Includes a standard steel expander button for unturned commercial brass alongside a decapping pin retainer for sizing uniform neck-turned brass without an expander ball.
• Independent Body Die: Restores critical case dimensions and bumps shoulders back without disturbing the neck, extending brass life for fire-formed cases.
• Standard Seating Die: Features a Series 92000 bullet seating assembly with an integrated crimping shoulder for reliable bullet retention.
• Universal Press Interface: Standard 7/8"-14 threading ensures mechanical compatibility with standard workshop reloading presses.
