The RCBS 300 PRC Full Length Die Set (Model R28601) is a premium two-die steel set engineered for handloaders reloading bottleneck rifle cartridges. Machined from hardened proprietary die steel, this manual reloading tool is built to withstand high-volume reloading pressures. It is designed to resize fired brass cases back to SAAMI minimum dimensions and seat bullets with reliable precision. Operating on a standard thread interface, this mechanical set is fully compatible with standard Australian reloading presses.

Key Features

  • Full-Length Sizing Die: Resizes the exterior of the brass case back to SAAMI minimum dimensions, de-primes spent primers with the expander-decapping unit, and expands the neck to accept a new bullet.
  • Vent Holes: Integrated vent holes release trapped air during the sizing process, protecting the brass case from damage caused by excessive lubricant.
  • Bullet Seating Die: Features an integrated roll crimper that allows the user to seat the bullet and apply a secure roll crimp simultaneously.
  • Premium Construction: Crafted from hardened steel, finished to high tolerances, and designed to prevent changes to the case body length during sizing.

Who is the Rcbs 300 Prc Full Length Die Set for?

  • Handloaders reloading 300 PRC for long-range shooting — who require a highly durable tool compatible with standard 7/8-inch (14 threads per inch) reloading presses to resize bottleneck brass back to exact SAAMI minimum cartridge dimensions.
  • Handloaders producing 300 PRC ammunition for hunting — who utilize the RCBS 300 PRC Full Length Die Set to ensure secure bullet tension and reliable chambering by utilizing the integrated roll crimper and standard 7/8-inch dies.

Less suitable for: Reloaders working with other calibres, as this set is strictly limited to .300 PRC cartridges and cannot resize or seat 6.5 PRC or 7mm PRC variants. It is also less suitable for extreme long-range competitive shooters who require exact, micrometer-adjustable seating depths to tune bullet seating; these users should instead look for a premium micrometer-style seating die.
