Will this die set work with my standard reloading press in Australia?

Yes, the Redding 66287 Premium Series die set features industry-standard 7/8"-14 threads, making it fully compatible with all common single-stage and progressive presses used in Australia, such as Redding, RCBS, Hornady, and Lee. Please note that you will need to separately source a standard #10 shellholder, such as the Redding #RE11010, as it is not included in the box.

Does the full-length sizing die require inside-neck lubrication for .204 Ruger brass?

No, this die comes equipped with a factory-installed free-floating carbide size button. The carbide surface drastically reduces friction as it is pulled back through the tiny .204 case neck, eliminating the need for inside-neck lubrication and helping to prevent brass neck stretch during high-volume varmint prep cycles.

How precise are the bullet seating depth adjustments on the seating die?

The standard seating die included in this set features an engraved micrometer top that replaces traditional adjustment screws, allowing you to make precise, repeatable bullet seating depth adjustments in increments of 0.001 inches. This ensures exceptional overall cartridge length (COAL) consistency for tight concentricity when loading small-calibre varmint rounds.

Can I use this 204 Ruger die set to reload other .20-calibre cartridges like .20 Tactical?

No, this die set is built strictly for standard .204 Ruger brass cases. Attempting to use it on other .20-calibre variants like .20 Tactical or .20 Vartarg will result in shoulder or chamber mismatches due to differing case dimensions.

204 Ruger Die Set - Redding 66287

The Redding 204 Ruger Premium Series Full Length Die Set (MPN: 66287) is a precision 2-die mechanical reloading system engineered for resizing and seating standard .204 Ruger rifle cartridges. Built to standard 7/8"-14 reloading press threading, this set includes a full-length sizing die equipped with a factory-fitted free-floating carbide size button and a standard bullet seating die featuring an integrated Bullet Seating Micrometer top. It restores fired brass to factory chamber dimensions, minimizes neck stretch during the expansion stroke without requiring inside-neck lubrication, and allows precise control over cartridge overall length (COAL).

Key Features

Factory-Installed Carbide Expander Button: Free-floating carbide design significantly reduces friction inside the .204 neck mouth on the expander upstroke, preventing case neck stretching and removing the need for inside-neck lube.
Bullet Seating Micrometer: Features an engraved micrometer adjustment mechanism that enables repeatable, direct bullet seating depth adjustments calibrated in 0.001" increments.
Full-Length Resizing: Resizes the cartridge body, sets back the shoulder, and expands the neck in a single stroke to ensure reliable feeding and chambering across bolt-action and semi-automatic rifles.
Universal Press Mounting: Industry-standard 7/8"-14 thread pattern integrates directly with standard single-stage and progressive reloading presses.

Who is the Redding 204 Ruger Premium Series Full Length Die Set for?

High-Volume Pest and Varmint Hunters — Standardises bulk case preparation using standard 7/8"-14 threaded reloading presses, eliminating internal neck lubrication steps via the integrated carbide expander to speed up reloading cycles for field shooting.
Handloaders Seeking Precise Concentricity — Provides direct, fine-tuned depth control using an integrated micrometer that adjusts bullet seating in exact 0.001" increments to establish uniform cartridge overall lengths across high-volume batches.

Less suitable for: Handloaders loading non-standard .20-calibre cartridges (such as .20 Tactical or .20 Vartarg) due to strict .204 Ruger internal dimension constraints, or precision reloaders requiring customisable neck-tension control who are better served by a bushing-style sizing die set.
