The Redding 300 Prc Body Die (Manufacturer SKU: 75776) is a precision cartridge-reloading tool engineered specifically for the .300 Precision Rifle Cartridge (.300 PRC). Designed for manual mechanical reloading presses, this die resizes the cartridge case body and bumps the shoulder position to maintain proper cartridge headspace and reliable chambering without contacting or resizing the case neck. Built from precision-machined, heat-treated steel, it features no internal moving parts or decapping assembly, allowing handloaders to separate case body sizing from neck tension management.

Key Features

  • Dedicated Case Body and Shoulder Resizing: Restores factory body dimensions and bumps the shoulder on fired brass without working or sizing the case neck.
  • No Internal Moving Parts: Functions without an expander ball or decapping rod assembly, eliminating internal friction and preventing unwanted neck runout during the sizing stroke.
  • Modular Handloading Integration: Designed to pair with bushing neck sizing dies or dedicated neck dies, giving reloaders independent control over neck tension and shoulder bump.
  • Heat-Treated Steel Construction: Precision-machined for long service life and supplied with a standard Redding lock ring for secure press setup.
  • Standard Press Mounting: Features standard 7/8"-14 threading for direct compatibility with standard reloading presses.

Who is the Redding 300 PRC Body Die for?

  • Precision handloaders tuning .300 PRC ammunition for long-range shooting — requires precision shoulder bumping and case dimension restoration on .300 PRC (.308" projectile diameter) cases using standard 7/8"-14 threaded reloading presses without altering finely tuned neck tension.
  • Handloaders seeking to extend brass case life through modular neck and body sizing — pairs with dedicated neck-sizing dies using Redding #6 shellholders to full-length resize cartridge bodies only when brass flow causes stiff bolt closure, minimising unnecessary work-hardening of .300 PRC brass.

Less suitable for: Reloaders who require spent primer expulsion during sizing, who should instead use a dedicated decapping die or standard full-length sizing die, and high-volume hunters seeking single-operation reloading who are better served by a traditional single-step full-length sizing die.
