What shellholder do I need to use with the Redding 80153 300 Winchester Magnum Die Set?

This die set requires a standard Redding #6 shellholder (Part #11006) or Competition Shellholder #6 (Part #11606), which must be purchased separately. The dies themselves feature an industry-standard 7/8"-14 thread, making them fully compatible with all standard single-stage, turret, and progressive reloading presses used in Australia.

Do I need to lubricate cartridge cases before using these steel dies?

Yes, case lubrication is mandatory prior to full-length sizing because these are precision-machined alloy steel dies rather than carbide. Failing to lubricate your .300 Winchester Magnum brass will result in a stuck case inside the sizing die.

Are there any electrical compliance marks or 240V power requirements for this set?

No, this is a purely mechanical, manually operated press-mounted tooling set with no electrical components. Therefore, 240V compatibility, Australian mains plugs, and SAA or RCM regulatory marks do not apply.

Will this full-length steel die set allow me to micro-tune neck tension or seating depth?

This 2-die set uses a standard threaded top-stem adjustment for bullet seating and does not feature a 0.001" micrometer dial or interchangeable neck sizing bushings. If you require precise match-grade neck tension tuning or micro-adjustments for VLD bullets, you would be better suited upgrading to the Redding Master Hunter Series or adding a Redding Bullet Seating Micrometer.

300 Win Mag Die Set - Redding 80153

The Redding 80153 300 Winchester Magnum Full Length Steel Reloading Die Set is a conventional 2-die tooling set engineered to resize, decap, and seat bullets for bottleneck rifle cartridges. Precision-machined from heat-treated alloy steel on Hardinge lathes and hand-polished, this die set restores fired brass to standard SAAMI factory minimum dimensions. Built to mount on standard reloading presses, it provides the primary operations required to produce consistent .300 Winchester Magnum ammunition for hunting and target shooting.

Key Features

Full-Length Sizing and Decapping: Resizes the case body, resizes the case neck, bumps the shoulder back, and decaps spent primers in a single press stroke to ensure reliable chambering across factory rifle actions.
Expander Assembly: Includes an internal expander ball and decapping rod assembly to uniform the inside neck diameter for seating .308 in (7.62 mm) diameter projectiles.
Seating Die with Built-In Crimp: Features a threaded top stem for adjusting bullet seating depth, alongside an integrated roll-crimp ring that can be disengaged for non-crimped match ammunition.
Alloy Steel Construction: Heat-treated steel construction machined to tight tolerances for thousands of reloading cycles when paired with mandatory case lubrication.
Standard Press Integration: Direct compatibility with industry-standard 7/8"-14 threaded single-stage, turret, and progressive reloading presses.

Who is the Redding 300 Winchester Magnum Full Length Die Set for?

Long-Range Hunters and Target Handloaders — Relies on precision-machined steel sizing to standardise .300 Winchester Magnum brass for firing .308 in (7.62 mm) diameter projectiles across bolt-action, semi-automatic, and lever-action platforms.
High-Volume and Multi-Rifle Reloaders — Uses a standard 7/8"-14 thread mounting interface and a #6 shellholder setup to full-length resize case bodies and bump shoulders, guaranteeing consistent chamber feed across multiple firearms.

Less suitable for: Precision benchrest shooters requiring neck-only tension adjustment without full body sizing (who are better served by bushing neck sizing dies), or handloaders needing 0.001" micrometer-dial seating depth adjustments and dedicated VLD stems (who require micrometer-adjustable competition seating dies).
