The Redding 80346 Full Length Reloading Die Set is a two-die mechanical tooling system engineered to resize spent cartridge cases and seat projectiles for the 9.3x74mm Rimmed (9.3x74R) bottleneck cartridge. Constructed from CNC-machined, heat-treated high-grade alloy steel, this set prepares brass to factory dimensional tolerances to ensure smooth cycling and reliable extraction in break-action, double rifle, and drilling platforms. The tooling is entirely mechanical, requires no electrical power, and features standard 7/8"-14 TPI threads for compatibility with standard single-stage and turret reloading presses.

Key Features

• Full Length Sizing Die: Returns the cartridge body, shoulder, and neck to factory dimensions while depriming spent primers via an integrated decapping rod assembly and neck expander button.
• Bullet Seating Die: Features an internal bullet guide to align and seat projectiles to the required overall length, complete with a built-in roll crimp ring.
• Press Compatibility: Utilises industry-standard 7/8"-14 TPI threading to interface with single-stage and turret reloading presses across major reloading tool brands.
• Precision Steel Construction: Precision-machined from high-alloy steel and heat-treated in atmospheric furnaces for durability during high-pressure sizing operations (requires case lubrication).

Who is the Redding Full Length Die Set for 9.3x74R for?

• Big Game Hunters Using Break-Action and Double Rifles — Requires reliable cartridge chambering for large game like sambar deer and water buffalo, where this full length reloading die set restores 9.3x74mm Rimmed cases to exact dimensional tolerances to ensure consistent extraction in hinged-breech actions.
• European Calibre Handloaders — Relies on reloading presses with standard 7/8"-14 TPI threads to process non-standard European brass, utilizing a dedicated Redding #6 shell holder interface to properly secure the rimmed case during the full-length resizing stroke.

Less suitable for: Precision target shooters requiring micrometer-adjustable seating depth adjustments down to 0.001" increments, who are better served by micrometer competition seating dies, or benchrest shooters who only need neck-sizing to minimise brass work-hardening on fire-formed cases, who are better served by dedicated neck-sizing or bushing dies.
