The Redding 78111 Type S Neck Die Set is a precision three-die reloading kit engineered for handloading .223 Remington and 5.56x45mm NATO brass. Constructed from heat-treated alloy steel, the set includes a Type S Bushing Neck Sizing Die, an independent Body Die, and a standard Series 92000 Bullet Seating Die. The system allows handloaders to manage neck tension using freely floating, interchangeable bushings without overworking case necks, while the dedicated body die allows shoulder bumping without altering neck dimensions. Built with standard 7/8"-14 threads, the dies mount into standard single-stage and turret reloading presses to load .224" diameter projectiles using Redding #10 shellholders.

Key Features:

• Interchangeable Bushing Sizing: Accepts self-centering neck bushings (typically .243" to .251") in .001" increments to size case necks to precise dimensions without excessive brass working.
• Adjustable Neck Sizing Depth: The decapping rod assembly adjusts vertically, allowing handloaders to size the full neck or only a partial length of the case neck.
• Independent Body Die: Restores critical case body dimensions and bumps shoulders back to maintain chamber clearance without contacting or altering the case neck.
• Dual Internal Configurations: Ships with both an expander ball for standard commercial brass and a decapping pin retainer for turned, uniform brass requiring no internal neck expansion.
• Knurled Steel Lock Rings: Heat-treated alloy steel construction with knurled lock rings ensures secure, repeatable die adjustments on the reloading bench.

Who is the Redding 78111 Type S Neck Die Set For .223 Remington Steel for?

• Precision benchrest shooters — loads dedicated bolt-action brass by utilizing interchangeable neck bushings within the .243" to .251" diameter range to control neck tension and minimize brass fatigue in fire-formed cases.
• Long-range marksmen — provides precise bullet alignment on standard 7/8"-14 threaded reloading presses by utilizing a dedicated body die and a Series 92000 seating die designed specifically for .224" diameter bullets.
• Varmint hunters — sizes fire-formed .223 Remington brass using a modular 0.79 kg steel die set that allows partial neck sizing and decapping without internal expander drag.
