What shellholder do I need to use with the Redding 77280 7mm SAUM Type S Full Length Die?

This die requires either a standard #6 Shellholder (Redding PN 11006) or a Competition Shellholder #6 (Redding PN 11606) to function correctly on your reloading press. Please note that shellholders and interchangeable neck bushings are sold separately.

Does this die come with neck bushings included, and what size range does it accept?

The die does not include neck bushings; they must be purchased separately in 0.001 inch increments. It is engineered to accept Redding Type S bushings ranging from 0.310 inch minimum to 0.318 inch maximum, allowing you to precisely fine-tune your neck tension.

Can I use the Redding 77280 die for standard 7mm Remington Magnum brass?

No, this specific model is exclusively designed for 7mm Remington Short Action Ultra Magnum (7mm SAUM) cartridge cases. It is not compatible with standard-length magnums like the 7mm Remington Magnum, which require a dedicated die model.

Does this reloading die require any electrical compliance or SAA/RCM approval for use in Australia?

No electrical compliance or SAA/RCM approvals are needed because this is a purely mechanical tool with no powered components. It features an industry-standard 7/8 inch-14 thread that fits seamlessly into single-stage or turret presses commonly used by Australian reloaders.

7mm RSAUM Sizing Die - Redding 77280

The Redding Type S Bushing Full Length Sizing Die (MPN: 77280) is a dedicated reloading die engineered specifically for the 7mm Remington Short Action Ultra Magnum (7mm RSAUM / 7mm SAUM) cartridge. Built with industry-standard 7/8"-14 threads, it simultaneously sizes the entire cartridge body and bumps the shoulder back to factory specification while utilising interchangeable neck bushings to accurately set neck tension without overworking brass. It operates with a free-floating, self-centring bushing mechanism to minimise runout and maximise concentricity for precision handloading.

Key Features

Full-Length and Custom Sizing: Restores fired cartridge case bodies to factory dimensions and sets shoulder headspace while allowing precise neck tension adjustment.
Self-Centring Bushing System: Allows the internal bushing to self-align along the case neck axis during the sizing stroke to reduce bullet runout.
Adjustable Decapping Assembly: Includes both a standard steel expander ball and a decapping pin retainer, giving reloaders the choice to size with or without an internal expander button.
Interchangeable Bushing Compatibility: Accepts Redding Type S neck bushings ranging from 0.310" to 0.318" in 0.001" increments (bushings sold separately).
