What tools is the Redding 06117 .17 Cal. Pilot Stop specifically designed to work with?

The Redding 06117 Pilot Stop is engineered primarily for use with Redding Case Neck Gauges and Redding Flash Hole Deburring Tools. It guides and centers .17 caliber cartridge brass to ensure accurate neck wall thickness measurements and consistent flash-hole uniforming depth.

Will this pilot stop fit standard 3/16-inch mandrels or other caliber sizes?

No. This model is built exclusively for small 9/64-inch (approximately 3.57 mm) diameter mandrels. It is designed solely for .17 Caliber (.172 inch) cartridge case necks such as .17 Hornet, .17 Remington, and .17 Fireball, and will not fit larger mandrels or calibres like .20 or .22.

Does this stainless steel reloading accessory require any electrical safety certifications for use in Australia?

As a 100% manual, unpowered precision CNC-machined stainless steel hand tool, the Redding 06117 requires no electricity, power plugs, or Australian SAA/RCM electrical safety certifications. It is freely importable and compliant for use on your reloading bench anywhere in Australia.

How does the physical design of the Redding 06117 prevent measurement errors during case prep?

This pilot stop features a proprietary undercut profile designed to avoid contact with imperfections, burs, or chamfering irregularities at the case mouth and neck/shoulder junction. This unique geometry maintains smooth alignment over the 9/64-inch mandrel for consistent indicator dial readings.

Who is the Redding 17 Cal. Pilot Stop - For 9/64 Mandrel for?

Benchrest handloaders prepping .17 Hornet brass — Requires precise neck wall uniformity sorting, using this reloading case neck gauge pilot to center .172″ case necks over small 9/64-inch (3.57 mm) mandrels without catching on case mouth irregularities.
Varmint rifle reloaders sorting .17 Remington and .17 Fireball cases — Relies on a dedicated .17 calibre case neck pilot stop to maintain concentric alignment on 9/64-inch (approx. 3.57 mm) shafts when checking runout or setting uniform flash-hole deburring depths.

It is also unsuitable for rotary case trimmers, which require dedicated trimmer cutter pilots.
