Redding’s model 06121 pilot stop is precision CNC machined from stainless steel for use with the company’s Case Neck Gauge and Flash Hole Deburring Tools. Engineered for .22 caliber with a 9/64″ mandrel, this small mandrel pilot stop is specifically suited for .17 & .20 caliber applications and small flash holes. The slightly undercut shape prevents pickup of imperfections at the case mouth or neck/shoulder junction, delivering smooth and accurate indicator readings when paired with the Case Neck Gauge.
The stainless steel construction resists corrosion through repeated reloading cycles. A slightly beveled edge facilitates insertion of the pilot inside the case neck. Whether performing neck turning, flash hole deburring, or precision case neck gauging work, this tool delivers reliable performance across the reloading process.
