The Redding 325 WSM Full Length Die Set is a precision two-die bottleneck reloading set engineered to restore fired .325 Winchester Short Magnum brass to factory SAAMI dimensions. Machined from heat-treated alloy steel, the set includes a full-length resizing die with an integrated decapping rod assembly and expander button, alongside a bullet seating die featuring a built-in crimp ring. Designed with industry-standard 7/8"-14 threads, this mechanical die set delivers reliable case extraction, uniform sizing across the entire case body, and consistent bullet seating depth for heavy-recoil magnum hunting loads.

• Full-Length Resizing and Decapping: Restores fired .325 WSM bottleneck cases back to SAAMI specifications across the case body, neck, and shoulder while knocking out spent primers in a single press stroke.
• Precise Bullet Seating and Roll Crimping: Seats projectiles consistently to target Cartridge Overall Length (COAL) with the option to apply a roll crimp to secure bullets during high-recoil hunting conditions.
• Heat-Treated Alloy Steel Construction: Precision-machined steel components fitted with knurled lock rings maintain consistent alignment and sizing tolerances through high-volume reloading sessions.
• Standard Thread Mounting: Operates on standard 7/8"-14 threaded single-stage and turret reloading presses without requiring proprietary adapters.

Who is the Redding 325 WSM Full Length Die Set for?

• Handloaders loading 325 Winchester Short Magnum hunting ammunition — Delivers full-length resizing and controlled roll-crimping on standard 7/8"-14 threaded presses to ensure heavy-recoil 325 Winchester Short Magnum cartridges chamber smoothly and retain secure projectile seating in hunting rifles.
• Reloaders processing mixed-source or range-fired 325 WSM brass — Resizes every critical dimension of fired cases back to factory SAAMI limits using a 0.55 kg two-die set, ensuring mixed-origin 325 WSM brass reliably cycles through factory rifle chambers.

Less suitable for: Handloaders firing brass exclusively through a single fire-formed bolt-action rifle chamber who require minimal brass work-hardening for extended case life; a dedicated neck sizing die or bushing die is better suited for that application. This set is also incompatible with other short magnum calibres including .270 WSM, 7mm WSM, and .300 WSM due to differing shoulder geometries and neck diameters.
