The Redding 223 Remington Small Base Die Set is a precision two-die reloading system designed to restore fired .223 Remington cartridge cases to minimum SAAMI dimensions. Manufactured in the USA from heat-treated alloy steel, this set includes a small base full-length resizing die and a standard seating die with an integrated crimping ring. It provides extra reduction along the case body and shoulder to guarantee smooth feeding, chambering, and extraction in firearms with tight clearances or rapid-cycling actions.

Key Features

  • Small Base Resizing: Compresses the lower case body diameter closer to minimum SAAMI specifications and sets the shoulder back further than standard full-length dies to prevent chambering resistance.
  • Two-Die Configuration: Includes one small base full-length sizing die with a decapping rod assembly and expander button, plus one seating die with a built-in roll crimp ring.
  • Precision Construction: CNC-machined from alloy steel and heat-treated in atmospherically controlled furnaces for long-term dimensional consistency.
  • Universal Press Mounting: Uses standard 7/8"-14 threading to fit single-stage and progressive reloading presses.

Who is the Redding 223 Remington Small Base Die Set for?

  • Competitive target shooters — Requiring reliable chambering of .224" diameter bullets in tight custom match chambers, this small base reloading die set sizes the case web and body down to minimum tolerances on standard 7/8"-14 thread presses.
  • Semi-automatic and rapid-action shooters — Needing flawless cycling in autoloading or pump-action .223 platforms, this small base reloading die set reduces case body dimensions and bumps the shoulder back to prevent chambering jams during rapid feeding.

Less suitable for: Standard-chambered bolt-action rifles, where standard full-length sizing dies or neck-sizing dies are preferred to avoid overworking the brass and reducing case life.
