Will the Redding 77428 Type S Die work with my standard .280 Remington cases?

No, this die is built strictly for SAAMI-spec .280 Remington Ackley Improved brass featuring a 40-degree shoulder angle. Attempting to use it with standard .280 Remington or standard 7mm-08 cases will result in shoulder distortion. You must use brass that has already been fire-formed to the Ackley Improved chamber.

Are sizing bushings included with the Redding 280 Remington Ackley Improved Type S Die?

No, sizing bushings are sold separately and are not included in the box. This die accepts standard Redding sizing bushings ranging from 0.305" to 0.313" in 0.001" increments, allowing you to select the precise bushing size that matches your specific brass neck wall thickness.

What press compatibility and shellholder do I need to set up this die in my Australian reloading bench?

The die features an industry-standard 7/8"-14 TPI thread, making it fully compatible with standard single-stage and turret reloading presses from brands like Redding, RCBS, Lyman, Hornady, and Lee Precision. For proper case retention, you will need a Redding #1 or Competition Shellholder #1, which is sold separately.

Can I use this die without the internal expander button for ultimate concentricity?

Yes, the die includes both a standard expander button and an undersized decapping pin retainer. This allows reloaders who prefer neck sizing without pulling an expander back through the case neck to configure the decapping assembly accordingly, or remove the internal rod entirely to use the unit as a standalone body die.

280 AI Die - Redding 77428

The Redding 280 Remington Ackley Improved Type S - Full Length Die is a precision reloading tool engineered to resize the entire case body, bump shoulders back, and deliver exact neck tension control in a single operation. Utilizing interchangeable sizing bushings, this die self-centres on the cartridge neck to minimize runout and maximize case concentricity. Built with industry-standard 7/8"-14 TPI threading, it integrates into standard single-stage and turret reloading presses to maintain consistent headspace and extend the working life of .280 AI brass.

Key Features

Full-Length Resizing with Bushing Control: Resizes the full case body and resets the shoulder while applying precise neck tension via interchangeable bushings.
Self-Centring Bushing Design: Allows the internal bushing to freely float and self-align on the case neck, reducing runout and improving concentricity.
Adjustable Decapping Assembly: Enables the operator to size either the entire neck length or set partial neck sizing.
Dual Expander Configuration: Includes both a standard expander size button and an undersized decapping pin retainer for sizing necks without pulling an expander through the brass.
Body Die Functionality: Can be converted to a body-only sizing die to bump shoulders and size the case body by removing the internal decapping rod assembly and bushing.

Who is the Redding 280 Remington Ackley Improved Type S - Full Length Die for?

Precision .280 Ackley Improved Handloaders — Requires exact neck tension adjustment across bushing increments from 0.305" to 0.313" to match specific neck wall thicknesses without overworking brass in a Type S Full Length Die.

Less suitable for: Standard .280 Remington cases with a 17.5° shoulder or .30-06 and 7mm-08 parent cases; standard non-Ackley chambers require a conventional non-bushing or dedicated standard .280 Remington full-length sizing die to avoid shoulder distortion.
