The Redding 375 Ruger Full Length Die Set (MPN: 80269 / 80269R) is a two-die rifle reloading set designed to return fired bottleneck brass to factory SAAMI dimensions and seat bullets for the .375 Ruger cartridge. Machined from heat-treated alloy steel on Hardinge Super-Precision lathes and finished with hand-polished internal surfaces, this mechanical reloading set operates via industry-standard 7/8"-14 TPI press threads. The set provides full-length case resizing, spent primer decapping, internal neck expanding, and bullet seating with a built-in roll crimp to prevent projectile displacement under heavy recoil.

Key Features

• Full-Length Resizing: Restores fired .375 Ruger brass to factory SAAMI cartridge dimensions to ensure dependable chambering and smooth extraction in bolt-action hunting rifles.
• Integrated Decapping and Expanding: Features a decapping rod assembly and expander button that removes spent primers while sizing case neck internal diameters in a single press stroke.
• Built-In Roll Crimp: The included bullet seating die features an internal crimping shoulder designed to secure heavy 0.375" (9.5 mm) diameter dangerous-game bullets against recoil-induced movement in magazine boxes.
• Precision Construction: Manufactured from heat-treated alloy tool steel with hand-polished internal cavities to reduce friction and brass galling during the sizing cycle.
• Included Storage Block: Ships in a plastic storage box that doubles as a cartridge loading block, along with a spare decapping pin and hex wrench.

Who is the Redding 375 Ruger Full Length Die Set for?

• Australian dangerous game hunters — requires full-length resizing to factory SAAMI specifications on standard 7/8"-14 TPI presses to guarantee flawless cycling for 0.375" (9.5 mm) diameter bullet loads in remote Top End water buffalo and scrub bull environments.
• Heavy-recoil rifle handloaders — provides an integrated internal roll crimp ring in the seating die to lock heavy dangerous-game projectiles securely in .375 Ruger cases against high recoil displacement in magazine wells.

Less suitable for: Handloaders loading belted .375 H&H Magnum cartridges, which possess distinct case dimensions and require dedicated .375 H&H Magnum die sets, or single-rifle precision shooters seeking to reuse fire-formed brass using neck-sizing die sets.
