What components are included in the Redding 60153 300 Win Mag Type S Elite Bushing Die Set?

This comprehensive 3-die set includes a Type S Bushing Full Length Sizing Die, a Type S Bushing Neck Sizing Die, and a Competition Bullet Seating Die featuring a micrometer top. It utilizes industry-standard 7/8"-14 threads, making it fully compatible with single-stage and turret presses commonly used by Australian reloaders.

Which shellholders and neck bushings do I need to use with this 300 Win Mag die set?

You will need a standard Redding Shellholder #6 (Part #11006) or Competition Shellholder Set #6 (#11606) to operate this set. For the sizing dies, bushings are sold separately and must fall within the .330" minimum to .338" maximum compatibility range for the 300 Winchester Magnum cartridge, such as the Redding 73333 heat-treated steel neck sizing bushing.

How do the micrometer and bushing features improve my 300 Win Mag handloads?

The micrometer seating die allows for precise cartridge overall length adjustments in 0.001" increments using a sliding alignment sleeve to center the case before bullet entry. Meanwhile, the interchangeable bushings let you fine-tune neck tension independently to minimise brass fatigue and reduce extreme spread and standard deviation for long-range target shooting.

300 Win Mag Die Set - Redding 60153

The Redding .300 Win Mag Type S - Elite Bushing Die Set (MPN 60153) is a precision 3-die reloading system engineered for the .300 Winchester Magnum cartridge (.308 in / 7.82 mm projectile diameter). Designed for standard 7/8"-14 threaded reloading presses, this mechanical set gives handloaders exact control over case dimensions, neck tension, and bullet seating depth. It includes a Type S Bushing Full Length Sizing Die, a Type S Bushing Neck Sizing Die, and a Competition Bullet Seating Die featuring a micrometer top graduated in 0.001" increments with an internal sliding alignment sleeve to minimise runout.

Key Features

Adjustable Neck Tension: Uses freely self-centering interchangeable bushings (sold separately) adjustable in 0.001" increments to precisely size case necks without overworking brass.
Dual Sizing Flexibility: Includes both full-length resizing for field reliability and neck-only sizing for fire-formed brass in bolt-action rifles. Removing the bushing allows the full-length die to function as a body sizing die.
Competition Micrometer Seater: Features 0.001" micrometer graduations and a spring-loaded alignment sleeve that centres the case and projectile prior to seating for consistent cartridge overall length (COAL).
Mechanical Compatibility: Operates on standard single-stage and turret presses using industry-standard 7/8"-14 threads and Redding #6 shellholders.

Who is the Redding 300 Win Mag Type S - Elite Bushing Die Set for?

Long-range target shooters — Need precise control over muzzle velocity standard deviation and extreme spread by micro-adjusting bullet jump via the seating die's 0.001" increments and matching neck tension using bushings between .330" and .338" in this 300 Win Mag reloading die set.
Hunters handloading 300 Win Mag ammunition for extended-range accuracy — Require full-length resizing across standard 7/8"-14 presses to ensure smooth chambering while maintaining precise bullet alignment down to 0.001" seating increments for consistent long-range trajectories.
Precision reloaders requiring both full-length and neck-only sizing options — Benefit from the dual-die setup in this 300 Win Mag reloading die set, allowing full-length body sizing or isolated neck sizing within the .330" to .338" bushing envelope to maximize brass lifespan across fire-formed cases.

Less suitable for: High-volume, bulk ammunition reloaders who do not require specific neck tension tuning within the .330" to .338" range, who are better served by a standard non-bushing 2-die sizing and seating set.
