Description
The Redding 22 Caliber Stainless Pilot Stop is one of those small pieces of gear that quietly makes your case prep better. Machined from solid stainless steel on CNC equipment, it's built to fit the standard 3/16" mandrel and pairs up with the Redding Case Neck Gauge and Redding Flash Hole Deburring Tools. If you're chasing consistency on .22 caliber (.224") brass, this is the part that keeps your measurements and prep honest.
What the 22 Cal Pilot Stop Brings to the Bench
The shape here is the whole story. Each pilot stop is slightly undercut, and that little detail does a lot of work. Instead of hanging up on dings, burrs, or imperfections right at the case mouth or the neck/shoulder junction, it rides past them. The result is a smoother feel on the mandrel and cleaner, more accurate readings on your dial indicator when you're checking neck runout and concentricity.
Matching the Right Stop to Your .22 Cal Brass
Redding makes these pilot stops in two body sizes, and this one is the standard 3/16" mandrel version (part number 06122). There's also a small 9/64" mandrel version for .22 cal, so it pays to know which mandrel your gauge or deburring tool runs before ordering. The 3/16" stops like this one also play nicely with case prep tools from other makers, so it isn't locked into the Redding ecosystem.
Built to Last on the Loading Bench
Stainless steel means it shrugs off handling, cleaning, and years of time in a drawer without rusting or losing its shape. A pilot stop is a caliber-specific part, so if you load multiple calibers you'll want one for each, and this is the piece that covers your .22 cal work. It's a simple, precise tool that earns its keep every time you prep a batch of brass for accuracy.

Frequently Asked Questions
What is the 22 Caliber Pilot Stop used for?
It fits onto a standard 3/16" mandrel so you can locate and support .22 caliber case necks during prep. Paired with the Redding Case Neck Gauge, it gives you smooth, repeatable dial indicator readings for checking neck runout and concentricity. It also works with Redding's Flash Hole Deburring Tools.
Does this pilot stop fit the 3/16" or 9/64" mandrel?
This one (part number 06122) is the standard 3/16" mandrel version for .22 caliber. Redding also offers a small 9/64" mandrel pilot stop for .22 cal (06121), so check which mandrel your gauge or tool uses before ordering to make sure you get the right fit.
Why is the pilot stop shaped the way it is?
The slightly undercut profile is designed so the stop won't catch on imperfections at the case mouth or the neck/shoulder junction. That keeps movement smooth on the mandrel and delivers cleaner, more accurate readings on your dial indicator.
Will this Redding pilot stop work with other brands of case prep tools?
Yes. The standard 3/16" mandrel pilot stops are built to work well with case preparation tools from other manufacturers, not just Redding's own gear. It's made from CNC machined stainless steel, so it holds its precision over time.
