The RCBS Flash Hole Case Pilot Stop (brand part no. 88139) is a caliber-specific adapter built to pair with the RCBS Flash Hole Deburring Tool for .45-caliber brass. RCBS sizes each pilot stop to a specific caliber so the deburring tool centers correctly and removes excess brass from the flash hole, reducing case-to-case variation for more consistent ignition. Reloaders use it as part of a case-prep routine aimed at tightening group sizes through more uniform brass. Among reloading equipment, this pilot stop favors precision handloaders dialing in .45-caliber brass consistency.
