What mandrel size and calibre is the Redding 06122 pilot stop designed for?

The Redding 06122 pilot stop is specifically engineered for .22/.224 calibre rifle case necks and requires a standard 3/16-inch diameter mandrel shaft. It features precision CNC-machined stainless steel construction with an undercut pilot profile to prevent interference with extreme case mouth burrs.

Can I use this 3/16-inch pilot stop with smaller 9/64-inch Redding mandrels or sub-calibres like .17 and .20?

No, this model is strictly incompatible with smaller 9/64-inch mandrels, which require the separate Redding part #06121. It is also incompatible with sub-calibres such as .17 or .20, as well as larger calibres like 6mm, 6.5mm, and .30 cal, all of which require their own calibre-specific pilot stop models.

What tools can the Redding 06122 pilot stop be paired with on the reloading bench?

This pilot stop is primarily designed as a replacement or calibre-specific accessory for the Redding Case Neck Gauge and Redding Flash Hole Deburring Tools. Because it is sized for standard 3/16-inch shafts, it can also cross-pollinate with standard 3/16-inch mandrels from various other reloading tool manufacturers.

Does this manual reloading accessory require any electrical compliance or special certifications for use in Australia?

No electrical compliance, battery inputs, or Australian SAA/RCM certifications are required because the Redding 06122 is a purely mechanical, non-powered reloading component. It is fully legal and unrestricted for sale and use across all Australian states and territories for precision handloaders.

Redding Pilot Stop - Redding 06122

The Redding 22 Cal. Pilot Stop - For 3/16 Mandrels (MPN: 06122) is a precision reloading accessory designed to center and support rifle brass during case neck measurement and preparation. CNC-machined from corrosion-resistant stainless steel, this pilot stop fits onto standard 3/16-inch diameter tool shafts, including the Redding Case Neck Gauge and Redding Flash Hole Deburring Tools. Its specialized undercut geometry intentionally clears interior neck-to-shoulder junctions and mouth burrs, providing smooth case rotation and highly repeatable readings on dial indicators without binding.

Key Features

Precision Undercut Profile: Machined with a specific relief geometry to prevent contact with internal case mouth burrs and shoulder junctions, ensuring consistent case alignment.
Durable Stainless Steel Construction: Manufactured from solid CNC-machined stainless steel for long-term wear resistance and corrosion protection on the reloading bench.
Standard Mandrel Fit: Engineered with a 3/16-inch internal diameter interface to fit Redding case neck tools and standard 3/16-inch aftermarket shafts.
Targeted Calibre Fitment: Sized specifically to support the internal neck dimensions of .22 calibre (.224-inch diameter) cartridge cases.

Who is the Redding 22 Cal. Pilot Stop - For 3/16 Mandrels for?

Precision Handloaders — requiring a .22 calibre (.224-inch) pilot stop to securely center cartridges like the .223 Remington and .22-250 Remington on a 3/16-inch mandrel during case preparation.
Competitive Target Shooters — measuring case neck wall thickness uniformity on a dial gauge using a dedicated .22 calibre (.224-inch) pilot stop that prevents internal burr contact on 3/16-inch shafts.

Less suitable for: Handloaders prepping sub-calibre cases such as .17 or .20, larger calibres such as 6mm, 6.5mm, or .30 cal, or those operating 9/64-inch mandrels; these applications require distinct, calibre-matched pilot stops or alternative small-diameter mandrel assemblies.
