The Redding .338 Federal Neck Sizing Die (MPN: 81264 / 81264R) is a dedicated reloading tool designed to resize only the case neck of fire-formed .338 Federal brass. By leaving the case body and shoulder at the exact dimensions established by the rifle's chamber, this die preserves fire-formed fit, prevents excessive brass working, and maintains bullet-to-bore alignment. Machined from hardened alloy steel, the die features an industry-standard 7/8"-14 thread for compatibility with standard reloading presses and is configured for projectiles measuring 0.338 inches in diameter.

Key Features

  • Neck-Only Resizing: Resizes only the neck portion of the cartridge case while depriming spent primers, leaving the body and shoulder fire-formed to the rifle chamber.
  • Enhanced Brass Longevity: Prevents overworking the case body and shoulder, reducing brass fatigue and stretching across repeated firing cycles.
  • Precision Alignment: Improves concentricity and accuracy by maintaining the custom chamber fit of fired brass in single-rifle setups.
  • Internal Assembly: Includes a hardened steel die body, standard steel lock ring (Part #01016), decapping rod assembly (Part #23837), decapping pin (Part #01060), and a 0.338-inch neck expander/size button (Part #16336).

Who is the Redding 338 Federal Neck Sizing Die for?

  • Precision handloaders reloading for bolt-action rifles — requires maintaining exact chamber fire-forming while establishing proper neck tension for 0.338-inch diameter bullets mounted via standard 7/8"-14 thread presses.
  • Hunters seeking extended brass life in single-firearm setups — avoids working the case body on fire-formed brass between firings, prolonging cartridge life and maintaining chamber alignment for 0.338-inch diameter projectiles without resizing the case shoulder.

Less suitable for: Reloading ammunition intended for semi-automatic, lever-action, or pump-action firearms, or sharing cartridges across multiple rifles; these actions require a full-length sizing die to ensure reliable feeding and chambering.
