The Redding Type S Match Bushing Neck Die Set (300 PRC, MPN 38776) is a precision three-die reloading system engineered for the .300 Precision Rifle Cartridge. Built from heat-treated, case-hardened alloy steel and threaded to the standard 7/8"-14 reloading press interface, this set provides precise control over neck tension, shoulder position, and seating depth. It includes a Type S Bushing Neck Sizing Die that accommodates interchangeable self-centring bushings, a dedicated Body Die for resetting case geometry without working the neck, and a Competition Bullet Seating Die with a straight-line floating sleeve system to deliver minimal bullet runout.

Key Features

• Precision Neck Tension Control: The Type S Bushing Neck Die utilises interchangeable bushings that freely self-centre on the case neck to size brass in exact increments, preventing excessive working of the case neck.
• Independent Body Resizing: The included Body Die bumps the cartridge shoulder and resizes the case body to chamber specifications without contacting or disturbing the fire-formed neck.
• Competition Micrometer Seating: Features a calibrated micrometer top adjustable in 0.001" increments alongside an internal floating seating stem to ensure straight-line alignment and repeatable bullet seating depth.
• Decapping Versatility: The neck die includes an adjustable decapping rod assembly featuring both a standard expander button and a decapping pin retainer for reloaders working with neck-turned brass.
• Standard Press Integration: Compatible with any standard reloading press accepting 7/8"-14 thread dies and interfaces with Redding #6 shellholders.

Who is the Redding 300 PRC Type S Match Neck Die Set for?

• Long-range precision rifle competitors — requires exact neck tension and seating depth repeatability, which this 300 PRC reloading die set achieves through interchangeable bushings and a competition seater adjustable in 0.001" increments on standard 7/8"-14 presses.
• Custom hunters reloading fire-formed brass — manages single-chamber .300 Precision Rifle Cartridge brass life by sizing the neck while preserving chamber-formed dimensions until the dedicated body die is needed.

Less suitable for: Semi-automatic platforms requiring full-length sizing for reliable feeding across all operating conditions; a dedicated full-length bushing die set provides the required body reduction for reliable cycling.
