The Redding Type S - Bushing Neck Sizing Die Set (.260 Remington) is a precision 2-die reloading set engineered to size case necks and seat bullets for fireformed .260 Remington brass. Designed for bolt-action rifle handloaders, this set includes a Type S Bushing Neck Sizing Die and a standard Bullet Seating Die. It features an industry-standard 7/8"-14 TPI thread interface compatible with standard single-stage and turret reloading presses, delivering precise neck tension control without working the case body or shoulder.

Key Features

• Interchangeable Bushing System: Utilises freely interchangeable sizing bushings available in precise 0.001" increments to fine-tune neck diameter and bullet retention without overworking brass.
• Self-Centering Bushing Design: The sizing bushing floats freely within the die body, self-centering on the case neck to minimise runout and maintain concentricity.
• Adjustable Decapping Assembly: Allows handloaders to size the full neck length or set partial neck sizing, with options to decap using the standard expander button or the included decapping pin retainer.
• Mechanical Bench Operation: Completely manual reloading operation requiring no electrical power, with a total set shipping weight of approximately 0.5–0.6 kg (1.1–1.3 lbs).

Who is the Redding 260 Rem Type S - Neck Die Set for?

• Precision Rifle Series competitors — who require exact neck tension control adjustable down to 0.001" increments using this 260 Remington neck die set to minimise concentricity runout across high-volume match strings.
• Long-range target shooters — who mount their dies into standard 7/8"-14 TPI single-stage or turret presses to size fireformed brass without disturbing fireformed body dimensions, maximising accuracy and brass longevity.
• Long-range pest and game hunters using 260 Remington — who tune case neck grip in 0.001" steps on a dedicated bolt-action rifle to maintain consistent velocity and tight grouping downrange.

Less suitable for: Handloaders sizing brass for semi-automatic or lever-action rifles, reloaders sharing ammunition across multiple distinct rifle chambers, or brass exceeding 3 to 5 reload cycles where shoulder expansion causes sticky bolt lift; these conditions require a full-length sizing die or dedicated body die to bump the shoulder back and resize the case body for reliable chambering.
