The Redding 223 Rem Body Die (MPN 75111) full-length resizes the case body walls and bumps the shoulder back on fired .223 Remington and 5.56×45mm NATO brass to restore proper chamber clearance. Designed with internal neck clearance, the die performs shoulder setback and body sizing without contacting the case neck, preserving custom neck tension and neck concentricity. It operates without an internal decapping assembly, expander ball, or sizing bushings, making it a dedicated companion tool for handloaders using neck-sizing dies who need to eliminate stiff bolt closure after multiple firings.

Key Features

• Neck-Clearance Resizing: Resizes cartridge body diameters and sets back the shoulder while completely bypassing the case neck to prevent altering established neck tension.
• Standard Press Integration: Built with standard 7/8"-14 mounting threads to fit standard manual or progressive single-stage reloading presses.
• Headspace Control: Restores factory headspace dimensions on fired brass when adjusted against standard Redding #10 or stepped Competition shellholders.
• Simplified Mechanical Design: Features a solid steel body with zero internal moving parts, decapping pins, or expanders to eliminate case stretch during extraction.

Who is the Redding 223 Rem Body Die for?

• Precision rifle competitors — requires standard 7/8"-14 thread press compatibility to bump shoulders back on work-hardened .223 Remington brass without disturbing the neck concentricity achieved by separate bushing dies.
• Benchrest shooters — uses a dedicated .223 Remington reloading body die to restore smooth bolt closure on tight-tolerance match chambers when repeated neck-sizing causes cartridge body expansion.
• Varmint hunters — relies on standard 7/8"-14 thread die tooling to batch-process high-volume .223 Remington cases for consistent field feeding while isolating body sizing from neck sizing operations.

Less suitable for: Handloaders seeking an all-in-one sizing operation that deprimes brass in a single pass (better served by a standard full-length sizing die), shooters running tight-chambered semi-automatic actions where standard SAAMI dimensions fail to cycle (better served by a small-base sizing die), or altered shoulder variants such as .223 Ackley Improved (better served by a cartridge-specific wildcat body die).
