What components are included in the Redding 300 AAC Blackout Deluxe Die Set, and do I need any additional parts to start reloading?

This 3-die set includes a Full-Length Resizing Die with a decapping rod and expander button, a dedicated Neck Sizing Die, and a Standard Bullet Seating Die featuring a built-in crimp ring and seating plug. You will also need to separately source a standard Redding Shellholder #10 or Competition Shellholder #10, as well as appropriate case lube, primers, powder, and projectiles to begin handloading.

Can I use the neck sizing die in this set for brass fired from my AR-15 semi-automatic rifle?

No, the neck sizing die included in the 84327 set is specifically intended only for fire-formed brass that will be re-chambered in the exact same bolt-action rifle. If you are loading ammunition for semi-automatic firearms or multiple different rifles, you must use the full-length sizing die to restore cases to factory SAAMI minimum dimensions for reliable feeding.

Does this reloading die set require any electrical compliance certification for use in Australia?

No, this is a strictly mechanical, non-powered metallic reloading tool that does not require an electrical input such as 240V mains power. Consequently, Australian electrical safety certifications like SAA and RCM are not applicable to this product.

Will this die set allow me to adjust neck tension using interchangeable bushings?

No, the Redding 84327 is a conventional non-bushing die set featuring fixed neck dimensions. If your precision reloading requires fine-tuning neck tension to within thousandths of an inch using interchangeable bushings like the Redding 73333, you would instead need to look at Redding's Type S Bushing Die lines.

300 AAC Blackout Die Set - Redding 84327

The Redding 300 AAC Blackout Deluxe Die Set (Part #84327) is a 3-die metallic cartridge reloading set precision-machined from heat-treated alloy steel on Hardinge Super-Precision lathes. Designed to load .300 AAC Blackout (7.62×35mm) ammunition with .308 in (7.82 mm) diameter projectiles, this set incorporates both full-length and neck-sizing operations alongside a bullet seating die. Threaded to the standard 7/8"-14 pitch, these dies mount directly into standard single-stage and turret reloading presses to deliver precise case concentricity, consistent shoulder positioning, and controlled bullet seating.

Key Features

Complete 3-Die Configuration: Includes a Full-Length Resizing Die with decapping rod and expander button (Part #91327), a Neck Sizing Die (Part #81327), and a Standard Bullet Seating Die with a built-in crimp ring.
Brass Longevity via Neck Sizing: The dedicated neck die resizes only the case neck and decaps spent primers without working the case body or altering the shoulder, reducing brass work-hardening for fire-formed cases.
Full-Length Sizing Reliability: The full-length sizing die restores fired cases to SAAMI minimum factory dimensions to guarantee smooth chambering across semi-automatic and multi-gun platforms.
Precision Construction: Manufactured from heat-treated alloy steel, hand polished, and ultrasonically cleaned for friction reduction and long service life.
Standard Press Mounting: Uses industry-standard 7/8"-14 threading fitted with standard Redding lock rings.

Who is the Redding 300 AAC Blackout Deluxe Die Set for?

Bolt-Action Precision Handloaders — requires the included neck sizing die to decap and size only the neck of .308 in fire-formed brass without resizing the case body, eliminating unnecessary brass fatigue and extending case life for dedicated .300 AAC Blackout (7.62×35mm) bolt rifles using standard 7/8"-14 presses.
Semi-Automatic and Multi-Platform Shooters — utilizes the included full-length resizing die to restore .300 AAC Blackout (7.62×35mm) cases back to factory dimensions, ensuring flawless feeding and chambering across semi-automatic platforms with a standardized 7/8"-14 die setup.

Less suitable for: Reloaders seeking to form or size alternative .30-calibre cartridges without dedicated tooling, handloaders loading brass fired across different rifles without full-length resizing, or precision target shooters requiring customisable neck tension adjustments in .001" increments (who require a dedicated Type S bushing die set).
