RCBS Flash Hole deburring Tool Case Pilot Stop Only .40/10mm

The RCBS Flash Hole Deburring Tool Case Pilot Stop Only .40/10mm is a precision case preparation component designed for handloaders who demand consistency and accuracy in ammunition production. This caliber-specific pilot stop works in conjunction with the RCBS Flash Hole Deburring Tool to eliminate excess brass debris from case flash holes—a critical step in reducing case variation that directly impacts ignition consistency and overall round quality.

Engineered specifically for .40 S&W and 10mm Auto calibers, this pilot stop provides the precise dimensional control needed to properly center the deburring cutting head on each case's flash hole. By removing burrs and raised material around the flash hole, this tool reduces pressure inconsistencies and improves primer pocket uniformity—factors that serious handloaders understand are foundational to sub-minute-of-angle accuracy.

The compact design integrates seamlessly into any reloading bench setup, and its lightweight construction makes it easy to manage during repetitive case processing sessions without fatigue. This pilot stop is essential for law enforcement armorer operations, competition reloaders, and precision shooters who process their own ammunition in volume. It pairs directly with the RCBS Flash Hole Deburring Tool for optimal performance.
