The Redding 84239 Deluxe Full Length Reloading Die Set is a premium 3-die system engineered specifically for handloading the .225 Winchester bottleneck cartridge (using .224" / 5.7mm diameter projectiles). Manufactured in Cortland, New York, the set includes a full-length sizing die with a decapping rod and neck expander button, a neck sizing die to resize fire-formed cases without working the body, and a standard bullet seating die with a built-in crimp ring. Machined from heat-treated alloy steel on precision lathes, hand-polished, and ultrasonically cleaned, these dies maintain strict SAAMI tolerances for uniform headspace and dependable chambering.

Key Features

  • 3-Die Versatility: Provides both a full-length sizing die for universal chambering and a dedicated neck sizing die to preserve fire-formed brass dimensions.
  • Extended Brass Life: Neck sizing reduces work-hardening on scarce .225 Winchester cartridge cases while maintaining tighter concentricity for bolt-action platforms.

  • Included Accessories: Ships with a durable storage box that doubles as a cartridge loading block, a spare decapping pin, and a hex wrench for adjustments.

Who is the Redding 84239 Deluxe Full Length Reloading Die Set For 225 Winchester for?

  • Handloaders maintaining legacy or custom .225 Winchester bolt-action rifles — provides standard 7/8"-14 TPI threaded full-length and seating dies built specifically to reliably cycle .224" diameter projectiles through vintage firearms like Winchester Model 70s or custom single-shot actions.
  • Reloaders seeking to extend rare .225 Winchester brass life via neck sizing — includes a dedicated neck sizing die that resizes only the case neck of .225 Winchester brass, eliminating unnecessary work-hardening of the fire-formed body while using standard Redding Shellholder #4 tooling.

Less suitable for: Reloading other .22-calibre bottleneck cartridges such as .223 Remington or .22-250 Remington (which require calibre-specific dies), or high-volume non-lubricated progressive loading (which requires carbide-ring sizing dies).
