What specific case calibres is the Redding 06132 pilot stop designed to fit?

The Redding 06132 pilot stop is engineered specifically for 8mm rifle cartridges, such as the 8x57mm IS (8mm Mauser) and 8mm Remington Magnum. It features an 8mm calibre compatibility to match nominal .319 to .323-inch case necks.

What size mandrel does this pilot stop require to mount correctly on my reloading tool?

This model is strictly designed to interface with standard 3/16-inch (0.1875-inch) diameter mandrels and shafts. It is incompatible with smaller 9/64-inch mandrels, which are reserved for smaller calibre families ranging from .17 to .20.

Does this mechanical reloading accessory require any electrical safety certification or 240V power in Australia?

No electrical compliance or SAA/RCM certification is required for the Redding 06132. It is a purely manual, unpowered precision benchtop tool machined from stainless steel, meaning it does not plug into Australian 240V mains power.

How does the undercut profile of the pilot stop improve the case preparation process?

The pilot stop features a proprietary, slightly undercut contour that prevents the tool from catching on minor burrs or imperfections at the case mouth or neck-shoulder junction. This ensures smoother 8mm case rotation and delivers highly accurate, consistent runout readings on your dial indicator.

8mm Pilot Stop - Redding 06132

Q: Which specific Redding tools can I use this pilot stop with on my reloading bench?

The Redding 06132 is dual-purpose and engineered for use with the Redding Case Neck Concentricity Gauge and the Redding Universal Flash Hole Deburring Tool (#06100). It will also fit other third-party reloading equipment that utilises a standard 3/16-inch mandrel interface.

The Redding 06132 8mm Caliber Pilot Stop For 3/16 Inch Mandrels is a precision-machined reloading accessory designed to locate and support 8mm cartridge cases during concentricity testing and flash hole preparation. Constructed from CNC-machined stainless steel, this pilot stop mounts directly onto standard 3/16-inch (0.1875-inch) diameter tool shafts. It features a proprietary undercut profile that accommodates case mouth variations without hanging up on burrs or the neck-shoulder junction. This allows smooth case rotation when reading runout on the Redding Case Neck Concentricity Gauge and provides a consistent, positive physical depth stop when paired with the Redding Universal Flash Hole Deburring Tool (#06100).

Key Features

Dual-Tool Compatibility: Interfaces with the Redding Case Neck Concentricity Gauge and Redding Universal Flash Hole Deburring Tool, as well as third-party reloading tools equipped with a 3/16-inch shaft.
Undercut Contour Profile: Engineered to seat inside new and resized 8mm case necks smoothly, preventing binding at the case mouth for consistent dial indicator runout readings.
Uniform Depth Control: Acts as an adjustable mechanical stop during flash hole deburring operations to prevent over-cutting into the cartridge web.
Stainless Steel Construction: CNC-machined from stainless steel for wear resistance and dimensional stability during continuous benchtop reloading.

Who is the Redding 8mm Pilot Stop for 3/16-Inch Mandrels for?

8mm Rifle Handloaders — Requires a 3/16-inch mandrel pilot stop configured specifically for 8mm (.323-inch nominal neck diameter) cases such as 8x57mm IS and 8mm Remington Magnum to establish a uniform depth stop during flash hole deburring.
Competitive Target Shooters — Relies on an undercut pilot contour sized for 8mm cartridge necks on a 3/16-inch shaft to achieve unimpeded case rotation and accurate neck runout measurements on a concentricity gauge.

Less suitable for: Reloaders working with calibres outside the 8mm (.323 inch) range or cartridges utilizing smaller 9/64-inch mandrels; these applications require calibre-specific pilot stops matched to non-8mm neck diameters or dedicated 9/64-inch pilot models.
