The Redding 83209r Trim Die is a precision reloading tool designed for manual case preparation of .45-70 Government brass. Machined from heat-treated, case-hardened alloy steel, the die features an ultra-hard flat top surface that allows reloaders to file-trim elongated cases flush using a standard flat file. Unlike standard full-length sizing dies that aggressively resize brass during the trimming step, this trim die is engineered with specific internal body clearances to securely hold .45-70 Government cases without over-working the metal. It mounts directly into standard reloading presses via industry-standard 7/8"-14 threading and also serves as an intermediate case-forming aid for custom brass projects.

Key Features

  • Precision File-Trim Design: Features a case-hardened, flat top surface allowing reloaders to quickly remove excess case neck length flush with a standard file.
  • Internal Clearance Profiling: Holds brass securely during trimming without subjecting the case body to unnecessary full-length resizing or work-hardening.
  • Standard Press Integration: Built with standard 7/8"-14 threads to mount into conventional single-stage or turret reloading presses.
  • Case Forming Capability: Functions as an effective intermediate forming die for custom brass conversion steps prior to final full-length sizing.
  • Durable Steel Construction: Machined from solid alloy steel on precision lathes and heat-treated for wear resistance against hardened metal files.

Who is the Redding Trim Die for .45-70 Government for?

  • Lever-action and single-shot rifle reloaders — requires standard 7/8"-14 threading and precise SAAMI-spec trimming for .45-70 Government brass fired in rifles such as the Marlin 1895, Henry, or Ruger No. 1.
  • Low-volume precision reloaders — allows manual file-trimming of .45-70 Government brass using a standard Redding Shellholder #18 without over-working or resizing the case body during low-to-moderate batch reloading sessions.

Less suitable for: High-volume brass processing where a motorised power case trimmer or lathe-style trimmer is required for rapid output, or for trimming cases significantly shorter than SAAMI specifications to seat Hornady FTX projectiles, which requires a dedicated short trim die or adjustable lathe trimmer.
