The Redding Type S Small Base Bushing Full Length Sizing Die (MPN: 77355) is a precision reloading tool engineered specifically for resizing .308 Winchester cases. By sizing the lower body and base diameter tighter than standard SAAMI-specification dies, it restores fired cases to dimensions that ensure smooth feeding, chambering, and extraction in demanding actions. Built around standard 7/8"-14 reloading press threading, this die integrates Redding's interchangeable neck bushing system to give reloaders precise control over case neck tension without overworking the brass.

Key Features

• Small Base Sizing: Reduces the lower body and case web dimensions slightly below standard full-length specifications, ensuring flawless cycling in semi-automatic, pump, or tight match chambers.
• Interchangeable Bushing System: Utilises freely floating, self-centering neck bushings (available in 0.001" increments) to maintain concentricity and allow fine adjustment of neck tension.
• Dual Internal Configurations: Comes with both an expander button for standard brass and a decapping pin retainer for turned-neck brass to minimise runout.
• Multifunctional Setup: Converts into a small base body die by removing the internal bushing, decapping assembly, and expander button.

Specifications

• Calibre Compatibility: .308 Winchester (0.308 in diameter projectiles)
• Thread Interface: Standard 7/8"-14 reloading press threads
• Required Shellholder: Redding Standard Shellholder #1 (Part #11001) or Competition Shellholder Set #1 (Part #11601) (sold separately)

Who is the Redding 308 Win Small Base Type S Full Length Die for?

• Semi-Automatic .308 Winchester Rifle Owners — Sizes fired brass down at the case web and lower body to ensure reliable feeding and extraction across rapid cycling actions using standard 7/8"-14 press setups.
• Match and Precision Target Shooters — Delivers exact neck-tension control in 0.001" increments while sizing .308 Winchester cases to reliably chamber within tight custom or undersized match chambers.

Less suitable for: Standard bolt-action rifles featuring standard SAAMI-spec factory chambers, where a standard full-length bushing die or neck sizing die is preferred to extend brass life and prevent unnecessary working of the case web.
