The Redding Master Hunter Deluxe 3-Die Set for .300 PRC (MPN: 29776) is a precision reloading kit engineered for handloaders seeking match-grade ammunition consistency combined with field reliability. Built with industry-standard 7/8"-14 TPI threads, this set includes a Full-Length Sizing Die featuring a free-floating carbide expander button to minimise neck stretch without inside-neck lubrication, a standard Neck Sizing Die for working fire-formed cases, and a Competition Bullet Seating Die. The seating die utilizes an internal alignment sleeve to support the projectile and case neck simultaneously, paired with a top-mounted micrometer graduated in 0.001" increments for precise, repeatable control over bullet seating depth and cartridge overall length.

Key Features:

• Full-Length Sizing Die with Carbide Button: Restores fired brass to SAAMI chamber dimensions while the free-floating carbide expander ball reduces friction and brass fatigue on the case neck.
• Dedicated Neck Sizing Die: Enables sizing of fire-formed brass fire-formed to a specific rifle's chamber, extending case life for range work and load development.
• Competition Bullet Seating Die: Aligns both bullet and cartridge neck in a precision-ground sliding sleeve prior to seating to ensure straight-line alignment and near-zero runout.
• 0.001" Micrometer Adjustment: Allows handloaders to set precise jump-to-lands distances and cartridge overall length without trial-and-error adjustments.
• Standard Press Mounting: Uses standard 7/8"-14 TPI threading to interface with conventional single-stage and turret reloading presses.

Who is the Redding 300 PRC Master Hunter Deluxe Die Set for?

• Precision long-range hunters shooting .300 PRC bolt-action rifles — who require SAAMI-spec feeding reliability and rapid cartridge overall length adjustments via the micrometer graduated in 0.001" increments on this rifle die set.
• Extreme Long Range (ELR) handloaders seeking match-grade accuracy and low runout — who use standard reloading presses threaded for 7/8"-14 TPI to size .300 Precision Rifle Cartridge (.300 PRC) brass with both full-length and dedicated neck-sizing configurations.

Less suitable for: Handloaders operating compact C-frame or progressive presses with less than 4.25" to 4.5" of ram stroke clearance, where a dedicated large-window single-stage press is required to clear long .300 PRC assemblies, or shooters loading other .30-calibre magnums like .300 Win Mag or .300 RUM, who require a calibre-specific die set matching those shoulder dimensions.
