The Redding 358 Norma Magnum Full Length Die Set (Model 80210) is a dedicated two-die reloading system engineered to resize fired brass and seat projectiles for rifles chambered in .358 Norma Magnum. Manufactured from precision-machined, heat-treated alloy steel, this set returns brass cases to factory SAAMI/CIP dimensional specifications to ensure reliable feeding and chambering in hunting rifles. The set includes a full-length sizing die equipped with a decapping rod assembly and standard size button, alongside a bullet seating die with an integrated roll-crimp ring to secure heavy-recoil hunting projectiles.

• Full-Length Resizing: Restores case body dimensions, bumps the shoulder back, decaps spent primers, and expands the case neck to the correct internal diameter for proper neck tension.
• Precise Bullet Seating: Houses an internal alignment system and standard seat plug that seats bullets straight, complete with a built-in crimping shoulder to prevent projectile movement under magnum recoil.
• Standard Press Interface: Machined with industry-standard 7/8"-14 threads to mount into standard single-stage and turret reloading presses.
• Component Upgradability: Accommodates optional Redding carbide expander buttons and micrometer seating plugs without modifying the die bodies.

Who is the Redding 358 Norma Magnum Full Length Die Set for?

• Australian Big-Game Hunters — requires reliable case chambering when handloading .358" diameter bullets for large species like feral water buffalo and sambar deer, utilizing this full length die set to maintain factory clearances under harsh field conditions.
• Heavy-Calibre Handloaders — requires standard 7/8"-14 thread press compatibility to restore fired magnum brass back to factory dimensional specifications while providing built-in roll crimping for high-recoil hunting cartridges.

Less suitable for: Benchrest or extreme long-range target shooters seeking ultra-precise neck tension control without working the entire case body, where specialized bushing dies (such as Type S-Bushing dies) or neck-sizing dies are better suited. Case lubrication is strictly required; using cases dry risks stuck cases in the steel sizing die.
