Redding Master Hunter Carbide Die Set, .300 Win Mag

The Redding Master Hunter Carbide Die Set, .300 Win Mag (Redding part no. 28153) gives .300 Win Mag handloaders a full-length sizing die and a Redding Competition seating die matched to one of the most popular hunting and precision cartridges on the market. Redding builds this set for reloaders who want dependable, chamber-ready brass without stepping up to a full bench-rest bushing setup. The carbide expander button in the sizing die means no case lubrication is needed on the neck, speeding up bench time. It is built to Redding’s standard tolerances and drops straight into any single-stage or turret press already set up for standard-diameter dies.

Key Specifications

• Precision-machined for .300 Win Mag, sized to that cartridge’s exact case dimensions.
• The carbide expander button eliminates the need to lube case necks before sizing, cutting a step out of every reloading session.
• The full-length sizing die resizes the entire case body and bumps the shoulder back, so brass chambers reliably in any rifle, not just the one it was fired in.
• The included Redding Competition seating die uses a micrometer head adjustable in 0.001-inch increments for repeatable bullet seating depth.
• Fits any press with the industry-standard 7/8-14 die thread, no adapter needed.
• The die box includes a spare decapping pin and hex wrench, plus a slot for the shellholder.
