What caliber and cartridge is the Redding 71280 Type S die specifically designed for?

The Redding 71280 Type S die is precision-machined specifically for the 7mm Remington Short Action Ultra Magnum (7mm Remington SAUM or 7mm RSAUM) cartridge, which utilizes a 0.284-inch bullet diameter. It features a standard 7/8"-14 reloading die thread that fits most single-stage and turret presses used by Australian handloaders.

Do I need to purchase any additional accessories to start neck-sizing with this die?

Yes, because the die relies on an interchangeable system, you will need to separately acquire a Standard #6 shellholder (such as Redding PN 11006 or Competition #11606) and appropriate Redding Type S steel or titanium nitride sizing bushings in .001" increments. These components are essential for setting your desired neck tension and securing the brass in your reloading press.

Can I use this neck sizing die for cartridges fired out of multiple different rifles or semi-automatics?

No, neck sizing is strictly designed for previously fire-formed brass intended to be re-chambered in the exact same bolt-action rifle. If your brass begins to bind or fail to chamber smoothly, or if you are loading ammunition for semi-automatic rifles or multiple firearms, you will need to transition to a full-length sizing die or dedicated body die.

Does this reloading die require any electrical compliance or special Australian certifications?

As a purely mechanical tool operated manually on a reloading press, the Redding 71280 die does not require electrical power, 240V mains compatibility, or SAA/RCM certifications. It is crafted from high-grade alloy tool steel suited for standard indoor bench reloading environments.

7mm SAUM Neck Die - Redding 71280

The Redding Type S Bushing Neck Die (MPN 71280) is a dedicated precision reloading tool designed specifically for the 7mm Remington Short Action Ultra Magnum (7mm RSAUM). It resizes only the neck portion of fire-formed cartridge cases while leaving the body and shoulder dimensions unchanged. This process preserves the exact chamber fit of cases fired in a specific rifle, extending brass life, optimising neck concentricity, and minimising bullet runout. The die mounts to standard single-stage or turret reloading presses via an industry-standard 7/8"-14 thread interface.

Key Features

Precision Neck Sizing: Resizes only the case neck area without working or altering the body or shoulder, maintaining fire-formed case dimensions.
Self-Centring Bushing System: Utilises freely floating, interchangeable Type S sizing bushings (sold separately in 0.001" increments) to maintain concentricity and reduce bullet runout; also accepts compatible bushings from Hornady, RCBS, and Wilson.
Dual Assembly Configurations: Supplied with an adjustable decapping rod, a standard expander button for commercial brass, and a decapping pin retainer for reloaders using neck-turned brass who prefer sizing solely via external bushing contact.
Partial Neck Sizing Capability: Allows reloaders to adjust the decapping assembly vertically to resize a fraction of the overall neck length.
Standard Press Integration: Features standard 7/8"-14 threading for direct compatibility with common reloading presses.

Who is the Redding Type S Bushing Neck Die for 7mm Remington SAUM for?

Australian precision shooters and F-Class competitors — requires precise neck tension control when seating .284 caliber projectiles into fire-formed 7mm RSAUM brass using interchangeable bushings in 0.001" increments on standard 7/8"-14 threaded reloading presses.
Long-range hunters handloading for custom bolt rifles — sizing fire-formed 7mm Remington SAUM cases to preserve custom chamber fit without overworking the brass, mounting to standard 7/8"-14 thread presses to load .284 caliber hunting projectiles.

Less suitable for: Reloaders whose fire-formed brass has expanded to tight chamber limits causing stiff bolt closure, or those loading for semi-automatic actions and multiple rifles, where a full-length sizing die or dedicated body die is required to restore factory body and shoulder clearance.
