What reloading presses are compatible with the Redding 458 Socom Full Length Die Set?

This die set features industry-standard 7/8"-14 threading, making it fully compatible with all standard single-stage, turret, and progressive reloading presses commonly used in Australia, such as those from Redding, RCBS, Hornady, Lee, Lyman, and Dillon.

What additional accessories do I need to start reloading .458 SOCOM with this set?

In addition to the 2-die set—which includes the full-length sizing die and the bullet seating die with a built-in crimp—you will need a standard Redding #1 shellholder (Part #11001) or competition shellholder (#11601) to hold the brass in your press.

Does this die set include electrical components or require SAA/RCM certification for use in Australia?

No. The Redding 80444 is an entirely mechanical tool constructed from heat-treated alloy steel and requires no mains electricity, battery power, or electrical certifications such as SAA or RCM to be sold or operated in Australia.

How should I maintain these steel dies to protect them from corrosion in humid Australian environments?

Because the set is machined from heat-treated alloy steel, you should apply a standard protective gun oil or rust preventative wax to the exterior and interior surfaces after use. Proper lubrication also prevents stuck cases when full-length resizing .458 SOCOM bottleneck brass in variable outback climates.

.458 SOCOM Die Set - Redding 80444

The Redding 458 Socom Full Length Die Set is a precision two-die reloading system engineered to return fired brass to factory dimensions and seat projectiles for reliable cycling. Machined from heat-treated alloy steel on precision CNC lathes, this set restores expanded bottleneck cases to proper chamber tolerances while decapping, expanding, and seating bullets in standard reloading presses.

Key Features

Full-Length Sizing and Decapping: The full-length sizing die (Part #91444) resizes the entire case body and neck while using an integrated decapping rod assembly and expander button to remove spent primers and expand case mouths in a single stroke.
Bullet Seating with Integrated Crimp: The seating die (Part #92444) provides uniform bullet seating depth and features a built-in crimp ring to secure projectiles against feeding forces and recoil.
Universal Press Interface: Machined with industry-standard 7/8"-14 threading to fit common single-stage, turret, and progressive reloading presses.
Reliable Chambering: Fully resizes fired cases to ensure reliable feeding and chamber clearance across semi-automatic and bolt-action firearm platforms.

Who is the Redding 458 Socom Full Length Die Set for?

Big Bore Hunters and Handloaders — requires full-length resizing of fired bottleneck brass and uniform seating of heavy 0.458" (11.63 mm) diameter projectiles to produce consistent, high-power hunting ammunition using this 458 Socom full length die set.
AR-15 Platform .458 SOCOM Shooters — needs full-length sizing to restore expanded case bodies back to standard chamber dimensions and an integrated crimp ring to retain 0.458" diameter bullets against rough magazine feeding forces.
