What reloading presses are compatible with the Redding 9.3x62 Mauser Neck Sizing Die in Australia?

This die features an industry-standard 7/8"-14 thread, making it directly compatible with all major single-stage, turret, and progressive reloading presses sold in Australia, including models from Redding, RCBS, Hornady, Lyman, and Lee. As a purely mechanical tool requiring no electricity, it does not involve 240V mains power, plugs, or electrical safety approvals like SAA or RCM certification.

Which shellholders do I need to use with the Redding 81345 neck sizing die?

You will need a standard Redding Shellholder #1 (Part #11001) or a Competition Shellholder #1 (Part #11601) to securely hold your 9.3x62mm Mauser cases during the sizing operation. These ensure proper alignment with the 7/8"-14 threaded press setup for consistent, concentric case necks.

How many times can I fire-form my 9.3x62mm brass before I need to stop using this neck sizing die?

The Redding neck sizing die is designed to size only the neck of fire-formed brass from your specific bolt-action or single-shot rifle to extend case life and improve accuracy. However, after typically 3 to 5 firings, cases will become tight or difficult to chamber, at which point you must switch to a Full Length Sizing Die (Redding #91345) or a Body Die to bump the shoulder and resize the body.

9.3x62 Mauser Neck Die - Redding 81345

The Redding 9.3x62 Mauser Neck Sizing Die (Part #81345) is a precision metallic cartridge reloading tool designed to resize only the neck of fire-formed 9.3x62mm Mauser cartridge cases. Manufactured from heat-treated, precision-machined alloy steel with hand-polished internal surfaces, this die leaves the body and shoulder dimensions undisturbed to maintain a fire-formed fit in a specific rifle chamber. It mounts to standard reloading presses via an industry-standard 7/8"-14 thread and integrates a decapping rod assembly with an expander button to remove spent primers and set the correct internal neck diameter in a single operation.

Key Features

Targeted Neck Resizing: Constricts only the case neck of bottleneck 9.3x62mm Mauser cases, preserving fire-formed body and shoulder dimensions to reduce brass work-hardening and extend case life.
Integrated Decapping and Expanding: Features a decapping rod assembly (Part #24364), decapping pin (Part #01060), and size button (Part #16364) to decap spent primers and establish inside neck clearance simultaneously.
Precision Machined Construction: Built from heat-treated alloy steel that is hand-polished to ensure smooth operation and consistent neck concentricity.
Standard Press Mounting: Uses standard 7/8"-14 die threads for compatibility with major single-stage and turret reloading presses.

Who is the Redding 9.3x62 Mauser Neck Sizing Die for?

Handloaders reloading for bolt-action or single-shot 9.3x62 Mauser rifles — fits reloading presses via standard 7/8"-14 threads to process fire-formed 9.3x62mm Mauser (.366 in / 9.3 mm bullet diameter) cases for repeat firing in the exact same firearm chamber.
Precision shooters seeking maximum case life and concentricity — sizes solely the neck of 9.3x62mm cases (.366 in / 9.3 mm diameter) to eliminate unnecessary body sizing and minimize brass fatigue over repeated reloading cycles.

Less suitable for: Fire-formed cases that have been fired across multiple rifles, brass intended for semi-automatic, lever-action, or pump-action firearms, or cases that have become difficult to chamber after 3 to 5 firings; these conditions require a full length sizing die or a dedicated body die to bump the shoulder and resize the cartridge body.
