The Redding 84776 Deluxe 3-Die Set is a precision reloading tool engineered specifically for SAAMI-spec .300 PRC (Precision Rifle Cartridge) bottleneck cases. Machined from heat-treated alloy steel on Hardinge Super-Precision lathes and hand-polished, this three-die set allows handloaders to perform full-length resizing, neck-only sizing, and bullet seating for .308 in (7.82 mm) diameter projectiles. Equipped with standard 7/8"-14 threads, these dies integrate directly with common single-stage and turret reloading presses.

Key Features

• Full-Length Resizing Die: Sizes the complete case body, restores factory headspace by bumping the shoulder, and de-caps spent primers while setting inner neck tension using an expander size button.
• Neck Sizing Die: Resizes only the neck and de-caps the brass without altering fire-formed case body dimensions or shoulder angles, extending brass life.
• Bullet Seating Die: Features an internal bullet alignment guide, built-in roll-crimp capability, and a standard seating plug for uniform projectile seating depth.
• Precision Construction: Heat-treated alloy steel construction hand-polished to maintain chamber tolerances across repeated reloading cycles.

Who is the Redding Deluxe 3-Die Set for .300 PRC for?

• Long-range precision shooters loading .300 PRC — Requires precise seating and sizing control for .308 in diameter projectiles using standard 7/8"-14 thread reloading presses.
• Handloaders seeking both full-length and neck-only sizing options for bolt-action rifles — Delivers both a full-length sizing die and a dedicated neck sizing die within a 0.68 kg to 0.75 kg 300 PRC reloading die set to preserve fire-formed brass dimensions or restore factory headspace as needed.

Less suitable for: Handloaders working with other .30-calibre magnum cartridges such as .300 Win Mag, .300 WSM, or .300 Norma Mag, which require dedicated calibre-specific sizing dies matching their distinct shoulder angles and case dimensions; or shooters resizing brass fired across multiple chambers, who require full-length sizing rather than neck-only sizing.
