Will the Redding 300 PRC Type S Full Length Die fit my standard reloading press in Australia?

Yes, this die features the industry-standard 7/8"-14 thread pitch, making it fully compatible with almost all standard single-stage and turret reloading presses available in Australia, such as models from Redding, Hornady, RCBS, and Lyman.

Are neck bushings and shellholders included with the Redding 77776 die set?

No, neck sizing bushings and a shellholder are sold separately. For .300 PRC brass, reloaders typically require bushings ranging from .331" to .339" in .001" increments (such as the Redding 73333 0.333-inch bushing if it matches your brass thickness) and a standard Redding #6 shellholder.

Can I use this 300 PRC die to resize other .30 calibre magnum cartridges like .300 Win Mag?

No, this die is engineered exclusively for the .300 PRC cartridge and is not compatible with other .30 calibre magnums such as .300 Win Mag, .300 WSM, or .300 Nosler due to differing body tapers and shoulder angles.

Does this reloading die require any electrical compliance certifications for use in Australia?

No, this is a purely non-powered mechanical reloading tool constructed from heat-treated alloy steel. Therefore, electrical certifications like SAA/RCM and 240V power compatibility are not applicable.

300 PRC Bushing Die - Redding 77776

The Redding Type S - Full Length Bushing Die (MPN: 77776) is a precision reloading tool engineered exclusively for resizing .300 PRC (.300 Precision Rifle Cartridge) brass cases. Built from precision-machined, heat-treated alloy steel, it performs complete case body resizing and shoulder setback to factory dimensions while allowing custom neck tension control via interchangeable sizing bushings. Operating on an industry-standard 7/8"-14 press thread standard, the die incorporates a self-centering floating bushing system to minimise bullet runout and maximise concentricity for long-range bolt-action rifle ammunition.

Key Features

Interchangeable Bushing Sizing: Accurately controls case neck sizing and bullet tension without overworking brass necks; accepts standard Redding bushings adjustable in .001" increments (typically .331" to .339" for .300 PRC).
Self-Centering Floating Bushing: Floats within the die body to naturally center on the case neck, maintaining critical cartridge concentricity.
Configurable Expander Assembly: Supplied with both an expander ball and a decapping pin retainer, allowing reloaders to size without an expander button when using neck-turned cases.
Adjustable Bushing Height: The decapping rod assembly adjusts vertically to permit full-length or partial-length neck sizing.
Dual-Purpose Operation: Can be converted to a body-only sizing die by removing the internal bushing and decapping assembly.

Who is the Redding Type S Full Length Die for?

Precision long-range target shooters — Requires precise neck tension control in .001" increments (typically using .331" to .339" bushings) combined with full-length body sizing to maintain consistent bullet release and tight velocity spreads in .300 PRC rifles.
Extreme Long Range (ELR) rifle competitors — Benefits from this full-length bushing sizing die to maintain SAAMI-spec chambering reliability and low concentric runout on .300 PRC match brass across standard 7/8"-14 threaded reloading presses.
Precision bolt-action hunters — Relies on this full-length bushing sizing die to ensure dependable cartridge feeding and chamber clearance for .300 PRC hunting rounds without sacrificing the brass-life benefits of tailored neck sizing.

Less suitable for: Other .30 calibre cartridges with differing body tapers or shoulder angles (such as .300 Win Mag, .300 WSM, or .30 Nosler), which require cartridge-specific full-length bushing dies; or fire-formed brass intended only for a single rifle chamber where shoulder bumping is unnecessary, which is better served by a dedicated neck-only sizing die.
