The Redding 17 Cal. Case Trimmer Pilot (5/32 Shank) is a precision-ground, hardened steel lathe accessory designed to guide small-bore cartridge case mouths during manual or powered case trimming. Engineered specifically for .17-calibre rifle cases, this pilot features a diameter of approximately .168" to .169" to ensure smooth entry into sized necks without binding or scratching the brass. By maintaining concentric alignment between the case neck and the cutting tool, it delivers uniform, square case mouths and consistent overall length across precision handloads.

Key Features

  • Precision Neck Alignment: Keeps .17-calibre cartridge necks concentric and square relative to the cutting blade during case trimming operations.
  • Lead-In Entry Taper: Features a slight taper at the tip for smooth insertion into sized case mouths without marring brass.
  • Hardened Steel Construction: Built from precision-ground, heat-treated steel for wear resistance across bench reloading sessions.
  • Dedicated Shank Sizing: Machined with a 5/32" (approx. 3.97 mm) shank diameter to match small-bore trimmer cutter heads.

Product Specifications

  • Calibre Application: .17 Calibre (e.g., .17 Hornet, .17 Remington, .17 Fireball)
  • Pilot Diameter: Approximately .168" to .169" (~.004" under standard bullet diameter)
  • Shank Diameter: 5/32" (approx. 3.97 mm)
  • Material: Heat-treated, precision-ground hardened steel
  • Tool Compatibility: Redding Model 1400 and Model 2400 Match Precision Case Trimmers fitted with a 5/32" cutter bore (such as part #14040), as well as compatible trimmers using a standard 5/32" pilot shank

Who is the Redding 17 Cal. Case Trimmer Pilot (5/32 Shank) for?

  • Varmint Hunters — requires a dedicated .168" to .169" pilot diameter to maintain square case mouths and precise overall length when preparing small-bore centrefire ammunition for fox and pest control.
  • Target Shooters — relies on the 5/32" shank diameter and lead-in taper of this case trimmer pilot to ensure concentric neck alignment without brass distortion when handloading .17 Hornet, .17 Remington, or .17 Fireball cartridges.

Less suitable for: Cartridge cases larger than .17 calibre (such as .204 Ruger or .22 calibre), which require calibre-specific pilots sized for standard 3/16" cutter shanks, or high-volume processing beyond bench lathe capacity, which is better served by automated on-press electric trimming dies.
