The Redding #12 Extended Shellholder (MPN: 11512) is a precision-machined, heat-treated steel reloading accessory engineered to elevate short cartridge cases above a standard press ram. Specifically designed for use with Redding File/Trim Dies, this extended shellholder provides the extra height required for cartridge cases with an overall length (O.A.L.) under 1.50 in (38.1 mm) to project fully through the top of the die for manual file trimming. It features a universal snap-in slotted interface compatible with standard single-stage and turret reloading presses.

Key Features

  • Extended Case Elevation: Machined with extra vertical height to raise short cartridge cases above the ram, facilitating proper case mouth exposure in file trim dies.
  • Precision Tolerances: Manufactured from heat-treated steel with strict dimensional concentricity to prevent case canting, uneven trimming, or rim deformation.
  • Universal Press Interface: Uses a standard snap-in slotted ram profile that mounts to standard single-stage and turret reloading presses.
  • Dedicated #12 Rim Geometry: Precisely fits cartridge families sharing the #12 rim dimension, ensuring secure case retention during case preparation strokes.

Who is the Redding #12 Shellholder Extended Ppc, 38/357 for?

  • Handloaders reloading .38 Special and .357 Magnum ammunition — elevates short handgun cases with an O.A.L. under 1.50 in (38.1 mm) above the press ram so the case mouth reaches through file trim dies for uniform length trimming.
  • Reloaders building and prepping 6.5 Grendel or PPC rifle cartridges using file trim dies — provides the vertical clearance necessary for short benchrest and intermediate rifle brass measuring under 38.1 mm (1.50 in) O.A.L. to clear standard press tooling during case forming and mouth trimming.

Less suitable for: Cartridge cases exceeding 1.50 in (38.1 mm) O.A.L., which require a standard-height #12 shellholder or competition shellholder set to avoid over-elevating the brass and losing proper die clearance.
