Will the Redding 77478 die work with my 6.5 Creedmoor or 6.5 PRC brass?

No, this die is dedicated exclusively to 6.5mm Grendel brass and features a standard 7/8"-14 threaded body. It is incompatible with other 6.5mm cartridges like 6.5 Creedmoor or 6.5 PRC due to differing case dimensions and shoulder angles.

What extra components do I need to purchase to start reloading with this die in Australia?

Because this is a Type S bushing die, you will need to separately purchase a Redding #12 shellholder and standard Redding interchangeable neck sizing bushings. Redding recommends a bushing range between .283" and .291" for 6.5 Grendel depending on your specific brass neck wall thickness.

Does this Redding 6.5 Grendel die require any electrical compliance or SAA/RCM certifications for use in an Australian workshop?

No electrical compliance, 240V ratings, or SAA/RCM certifications are required. The Redding 77478 is a fully mechanical, non-powered reloading tool designed to mount on standard 7/8"-14 presses commonly used across Australian reloading benches.

6.5 Grendel Sizing Die - Redding 77478

The Redding 6.5 Grendel Type S - Full Length Die (MPN 77478) performs full-length case body resizing, shoulder bumping, and neck tension adjustment in a single operation. Machined with a standard 7/8"-14 thread body, this non-powered reloading die is engineered specifically for 6.5mm Grendel cartridge brass (0.264" bullet diameter). By utilising interchangeable, self-centring neck sizing bushings, it eliminates excessive brass working and extends case life while maintaining concentricity for bolt-action and semi-automatic platforms.

Key Features

Dual-Function Resizing: Performs full-length case body sizing and precise neck tension adjustments in one pass.
Interchangeable Bushing System: Accepts self-centring steel or titanium nitride Redding Type S neck sizing bushings to set exact neck clearance without overworking the brass.
Adjustable Decapping Assembly: Features an adjustable decapping rod that allows full-length or partial-length neck sizing while maintaining proper alignment.
Adaptable Configurations: Includes a standard expander button for unturned brass, supports optional carbide expander buttons, and can function as a body die when the bushing and internal decapper assembly are removed.

Who is the Redding 6.5 Grendel Type S - Full Length Die for?

Precision match reloaders for bolt-action and AR-15 platforms — needing exact concentricity and reliable semi-automatic feeding for 6.5mm Grendel cartridges (0.264" bullet diameter) using standard 7/8"-14 threaded reloading presses.
Reloaders seeking extended case life — controlling neck tension within a precise .283" to .291" bushing range to prevent brass overworking compared to non-bushing 6.5 Grendel sizing dies.

Less suitable for: Other 6.5mm cartridges such as 6.5 Creedmoor or 6.5 PRC, single-rifle fire-formed brass where a dedicated neck-only sizing die extends brass life further, or bulk high-volume reloading where standard non-bushing full-length sizing dies are preferred.
