What dies are included in the Redding 84218 Deluxe Set and how do they differ in application?

This 3-die set includes a Full-Length Sizing Die, a Neck Sizing Die, and a Bullet Seating Die with a built-in roll crimp. The full-length sizer returns brass to SAAMI factory dimensions for reliable feeding in lever-action and pump-action rifles, while the neck sizer only resizes the case neck to extend brass life and improve accuracy in bolt-action or single-shot rifles.

Will this die set work with other .25-calibre cartridges like .250 Savage or .257 Roberts?

No, the Redding 84218 is strictly engineered for standard .25-20 Winchester bottleneck brass utilising .257-inch diameter projectiles. It is completely incompatible with other .25-calibre cartridges such as the .250 Savage, .257 Roberts, or .25-06.

What shellholder do I need to use this die set with my reloading press?

The die set features an industry-standard 7/8"-14 thread pitch that fits any standard reloading press, but a shellholder is sold separately. For this .25-20 Winchester set, you will need a standard Redding Shellholder #3 (Part #11005) or the Redding Competition Shellholder #11605.

Are there any Australian electrical or regulatory compliance requirements for this tool?

As the Redding 84218 is a fully mechanical reloading accessory requiring no electrical power, Australian 240V mains power, SAA/RCM certifications, and AU plug compatibility are not applicable. While the die set itself is non-controlled reloading equipment under Australian firearms legislation, remember that possessing powder and primers requires an appropriate state firearms licence.

25-20 Die Set - Redding 84218

The Redding 84218 25-20 Winchester Deluxe Reloading 3-Die Set is a specialised mechanical tool engineered for reloading custom centerfire ammunition for firearms chambered in .25-20 Winchester. Manufactured from heat-treated, CNC-machined alloy steel with an internal polish, this three-die set includes a Full-Length Sizing Die (Part #91218) with a decapping rod assembly, a Neck Sizing Die (Part #81218), and a Bullet Seating Die (Part #92218) equipped with an integrated crimping shoulder and seating plug (Part #01066). Built with an industry-standard 7/8"-14 thread pitch, it mounts directly into standard reloading presses and requires Redding Shellholder #3 (Part #11005) or Competition Shellholder #11605 (sold separately).

Dual Sizing Configuration: Includes both full-length and neck sizing dies, allowing handloaders to return brass to SAAMI factory dimensions for reliable feeding or size only the case neck to preserve fire-formed brass geometry and prolong case life.
Integrated Roll Crimping: The bullet seating die accurately positions .257" diameter projectiles while applying a firm roll crimp required for tubular magazine retention.
Precision-Machined Construction: Turned on CNC lathes from alloy steel, heat-treated, and hand-polished to minimise internal runout and prevent brass galling.
Universal Press Fitment: Standard 7/8"-14 thread pitch ensures compatibility across stationary benchtop reloading presses without requiring power or electrical interfaces.

Who is the Redding 25-20 Winchester Deluxe Reloading 3-Die Set for?

Handloaders shooting vintage lever-action or pump-action rifles — Full-length sizes fire-formed brass back to factory SAAMI dimensions using standard 7/8"-14 threaded reloading presses to ensure smooth cycling and reliable feeding across tubular magazines seating .257" diameter projectiles.
Reloaders requiring neck sizing for bolt-action or single-shot rifles — Utilises the dedicated neck sizing die to resize only the case neck for ammunition chambered specifically in .25-20 Winchester, preserving brass life and custom chamber fit without working the cartridge body.

Less suitable for: Handloaders seeking to load other .25-calibre rifle cartridges such as .250 Savage, .257 Roberts, or .25-06, which exceed the bottleneck dimensions of this tooling and require dedicated full-length sizing dies matched to their respective cartridge specifications.
