The Redding 75148 Body Die is a precision reloading tool engineered exclusively for .30-06 Springfield cartridge cases. Machined from heat-treated alloy steel, this die resizes the case body diameter and bumps the case shoulder back to restore correct chamber headspace without contacting or resizing the case neck. Designed without internal decapping pins or expander balls, it operates as a modular sizing solution that allows handloaders to manage neck tension independently, extending cartridge brass longevity by avoiding unnecessary working of the case neck.

Key Features

• Dedicated Body Sizing and Shoulder Bumping: Restores external case dimensions and bumps the shoulder (typically 0.001" to 0.002" for bolt-action rifles) without touching the neck.
• No Internal Decapping Hardware: Contains no decapping assembly, leaving depriming and neck-tension adjustments to separate, specialised tools.
• Modular Compatibility: Serves as an ideal companion to Redding Type S Bushing Neck Sizing Dies or Competition Neck Dies for precision case preparation.
• Hardened Steel Construction: Precision machined from heat-treated alloy steel to ensure tight tolerances and long service life.
• Standard Threading: Built to standard 7/8"-14 reloading press threading, ensuring compatibility across single-stage, turret, and progressive presses.

Specifications

• Calibre Compatibility: .30-06 Springfield (.308 in / 7.82 mm bullet diameter)
• Press Thread Pitch: Industry-standard 7/8"-14
• Required Shellholder: Redding Shellholder #1 (or equivalent standard #1 shellholder; sold separately)
• Material: Heat-treated, hardened alloy steel
• Weight: Approximately 200–250 g packaged

Who is the Redding Body Die for .30-06 Springfield for?

• Precision Bolt-Action Handloaders — Restores chamber clearance on fire-formed .30-06 Springfield brass by bumping shoulders 0.001" to 0.002" without disturbing the neck dimensions established by specialised neck-bushing dies.
• Modular Brass-Prep Reloaders — Uses a dedicated 7/8"-14 threaded body die to isolate case-body dimensional resizing from neck sizing and depriming, extending the working life of .30-06 Springfield brass cases.

Less suitable for: Handloaders cycling ammunition through semi-automatic service rifles like the M1 Garand (which require a small base body die or small base full-length die to size brass down to minimum SAAMI dimensions for reliable feeding), or reloaders seeking single-pass processing to deprime, neck-size, and full-length resize in a single press stroke (which requires a standard full-length sizing die or Type S full-length die).
