The Redding 83341 8mm Lebel Form & Custom Trim Die is a specialised reloading tool designed to form and file-trim custom 8x50mmR and 8x51mmR Lebel cartridge brass on a standard benchtop reloading press. Cut to standard chamber dimensions rather than full-sizing profiles, this die permits direct case-mouth file trimming without causing unnecessary brass work-hardening or redundant full-length resizing. Machined from heat-treated, case-hardened steel, it allows handloaders to run a flat metal file directly over the top surface to square and trim cases to exact length during case-forming procedures.

Key Features

• Chamber-Dimension Profiling: Machined to standard 8mm Lebel chamber dimensions to support case walls and allow precise file trimming without overworking or undersizing the brass.
• Case-Hardened Steel Construction: Features a hardened top face designed to withstand direct contact with metal hand files during manual trimming.
• Case Forming Functionality: Functions as an intermediate step when converting donor brass, such as necking down large-rim cases into 8mm Lebel brass.
• Standard Thread Mounting: Built with industry-standard 7/8"-14 UNC threads for direct compatibility with standard single-stage and turret reloading presses.

Specifications

Who is the Redding 8mm Lebel Form & Custom Trim Die for?

• Vintage military rifle shooters — Handloads 8x50mmR/8x51mmR Lebel ammunition for historical Lebel 1886 or Berthier rifles using an 8mm Lebel form and trim die threaded to the standard 7/8"-14 reloading press interface.
• Custom cartridge fabricators — Forms and squares hard-to-source 8mm Lebel brass from larger donor parent cases, securing the rimmed case via standard Redding Shellholder #26 compatible with standard 7/8"-14 UNC press rams.

Less suitable for: High-volume processing requiring hundreds of trimmed rounds per hour (where dedicated electric power case trimmers or lathe-style case trimmers are better suited), or as a standalone tool, as it requires a separate full-length sizing die and seating die to complete the ammunition loading process.
