The Redding 7mm TCU Deluxe Die Set (Mfg #84242) is a precision-machined 3-die system engineered specifically for handloaders working with the 7mm TCU (Thompson/Center Ugalde) metallic bottleneck cartridge. Constructed from heat-treated alloy steel that is precision-ground and hand-polished, this mechanical set provides both full-length resizing and fire-formed neck-sizing capabilities. It mounts to standard reloading presses via an industry-standard 7/8"-14 thread to process .284 in (7mm) diameter projectiles for single-shot, carbine, and custom bolt-action platforms.

Key Features

• Full-Length Sizing Die (#91242): Restores fired cartridge cases to standard exterior dimensions, expels spent primers, and expands the case neck via an integrated decapping rod assembly.
• Dedicated Neck Sizing Die (#81242): Decaps and sizes only the neck of the case, preserving fire-formed brass dimensions to maximize concentricity and extend overall brass life.
• Bullet Seating Die (#92242): Features an internal bullet alignment guide, built-in roll crimping capability, and a standard #01067 seating plug for consistent seating depths.
• Standard Press Mounting: Uses a 7/8"-14 thread interface to ensure compatibility across standard single-stage and turret reloading presses.
• Mechanical Construction: Built from durable heat-treated alloy steel with an approximate package shipping weight of 0.5–0.7 kg (1.2–1.5 lbs).

Who is the Redding 7mm TCU Deluxe Die Set for?

• Metallic silhouette competitors running 7mm TCU chambers — sizes bottleneck brass using the dedicated neck sizing die to maintain precise fire-formed chamber fit and optimal projectile alignment with standard .284 in (7mm) bullets on 7/8"-14 thread presses.
• Handloaders utilizing Thompson/Center Contender single-shot pistols and carbines — extends cartridge brass life across repeated firings by allowing reloaders to switch between full-length sizing and fire-formed neck sizing for 7mm TCU brass using a standard #10 shellholder.
• Shooters operating custom 7mm TCU bolt-action rifles — provides precise shoulder maintenance and full-length case restoration using the 7/8"-14 thread full-length resizing die when cycling brass through tight custom bolt actions.

Less suitable for: Handloaders attempting to directly size raw, unformed .223 Rem parent brass or alternative TCU calibres like 6mm TCU and 6.5mm TCU, which require dedicated case-forming dies or calibre-specific die sets.
