The Redding Type S Bushing Neck Sizing Die for .20 Tactical (Part # 71660) is a dedicated reloading tool engineered to resize cartridge case necks while maintaining precise control over neck tension and runout. Designed for manual reloading presses with standard 7/8"-14 threading, this Category III die features an internal decapping assembly that secures the decap pin without requiring an expander button. Machined from heat-treated alloy steel in the USA, this die allows handloaders to decap spent primers and size .20 Tactical brass without stretching or overworking the case neck.

Key Features

• Bushing-Based Sizing: Uses interchangeable Type S sizing bushings (sold separately) to allow fine adjustment of neck tension without overworking cartridge brass.
• Expander-Free Decapping: Utilises an integrated decapping pin retainer to punch out spent primers, eliminating the traditional expander button to minimise neck runout on uniform brass.
• Partial Neck Sizing Capability: The fully adjustable decap rod assembly allows reloaders to size the entire neck or a chosen portion (such as 1/2 to 3/4 neck length).
• Precision Threading: Standard 7/8"-14 interface ensures compatibility with standard single-stage and turret reloading presses.
• All-Steel Construction: Manufactured from heat-treated American alloy steel for extended service life and consistent dimensional stability under ambient reloading conditions.

Who is the Redding Type S Bushing Neck Sizing Die for .20 Tactical for?

• Precision .20 Tactical varmint handloaders — requires standard 7/8"-14 reloading press threading to load for the .20 Tactical (.204" bullet diameter) cartridge family, providing controlled neck tension and reduced brass fatigue over high-volume shooting sessions.
• Benchrest shooters using turned or sorted .204 brass — enables decapping without an expander ball using a decap rod set to a 3/16" (approx. 4.8 mm) pin protrusion below the die body, eliminating inside-neck friction and preserving minimal cartridge runout.

Less suitable for: Handloaders running unsorted brass with highly variable neck wall thicknesses, or those reloading other .20-calibre cartridges outside the .20 Tactical family; a standard full-length sizing die with an internal expander ball is better suited for non-uniform brass.
