What press compatibility and shellholder do I need to use with the Redding 81159 neck sizing die?

The Redding 81159 features a standard 7/8"-14 thread pitch that fits virtually all standard single-stage and progressive reloading presses. For proper operation, you will need to pair it with a Redding Standard Shellholder #1 (Part #11001) or a Redding Competition Shellholder #1 (Part #11601) designed for the 8x57mm JS Mauser cartridge.

Can I use brass neck-sized with this die across multiple 8x57mm rifles in my collection?

No, cases neck-sized with the Redding 81159 should not be shared across different rifles. Neck sizing leaves the fire-formed brass tailored exclusively to the exact chamber dimensions of the specific rifle it was fired in, meaning it may not chamber smoothly or safely in a different firearm.

How often will I need to transition from this neck sizing die to a full-length sizing die?

After 3 to 5 reload cycles, or when chamber-closure during bolt operation begins to feel stiff, fire-formed brass will naturally expand to the limits of your rifle's chamber. At this stage, you must transition to a full-length sizing die or shoulder bump die to push the shoulder back before continuing the neck-sizing process.

Are there any electrical or regulatory compliance certifications required for this tool in Australia?

No electrical regulations apply because the Redding 81159 is entirely a mechanical reloading tool requiring no electrical power source. Therefore, 240V compatibility, AU power plugs, and RCM or SAA compliance certifications are not applicable for this product.

8mm Mauser Die - Redding 81159

The Redding 81159 Neck Sizing Die is precision-machined mechanical tooling engineered specifically for reloading the 8x57mm JS Mauser (8mm Mauser / 8x57 IS) bottleneck cartridge. Built with standard 7/8"-14 mounting threads, this conventional non-bushing die resizes only the cartridge case neck while leaving the fire-formed body and shoulder dimensions undisturbed. By preventing unnecessary brass working along the case walls, it extends case longevity, eliminates body runout, and retains custom-fit chamber dimensions for bolt-action rifles.

Key Features

Neck-Only Resizing: Resizes only the neck portion of fire-formed 8x57 JS cases, maintaining custom-formed chamber geometry and minimising bullet runout.
Extended Brass Life: Eliminates continuous full-length sizing and excessive brass work-hardening at the case walls and shoulder web.
Integrated Decapping Assembly: Deprimes spent primers simultaneously during the downstroke via an internal Decapping Rod Assembly (Part #24322) and replaceable Decapping Pin (Part #01060).
Precision Internal Expander: Features a factory-fitted 0.323" Expander Size Button (Part #16322) designed to establish consistent neck tension for standard 8mm JS projectiles.
Universal Press Mounting: Uses industry-standard 7/8"-14 threading to fit single-stage and progressive reloading presses.

Who is the Redding 81159 Neck Sizing Die for?

Bolt-Action Military Surplus and Sporter Handloaders — requires standard 7/8"-14 thread press compatibility to resize fire-formed brass exclusively for the exact same chamber, maintaining custom fit across Karabiner 98k and sporterized 8x57 JS platforms without overworking case walls.
Precision Medium-to-Large Game Hunters — utilizes a precision 0.323" expander button to ensure consistent neck tension and reduced bullet runout for tightened group spreads when handloading dedicated 8x57mm JS hunting ammunition.

Less suitable for: Reloaders loading ammunition for semi-automatic, pump-action, or lever-action firearms, handloaders sharing ammunition across multiple different rifle chambers, or brass that has reached 3 to 5 reload cycles with stiff bolt closure; these applications require a full-length sizing die to restore factory-dimensioned body and shoulder clearances.
