The Redding Case Neck Gauge Pilot Stop (MPN: 06130) is a dedicated reloading tool accessory engineered to locate and support the inside neck of .30-calibre brass cases during precision case preparation. Designed for use with the Redding Case Neck Gauge and Redding Flash Hole Deburring Tools, this component mounts onto standard 3/16-inch (0.1875 in) diameter mandrels. Constructed from precision CNC-machined stainless steel, it provides a stable bearing surface to measure neck-wall thickness variations or establish uniform depth limits when deburring internal flash holes.

  • Calibre-Specific Alignment: Sized specifically for .30-calibre (7.62 mm) case necks, ensuring exact concentric alignment without loose play or binding during case rotation.
  • Undercut Relief Profile: Engineered with an undercut profile that prevents the bushing from catching or riding on internal imperfections at the case mouth or neck/shoulder junction, facilitating smooth rotation and accurate dial indicator readings.
  • Mandrel Compatibility: Machined with an internal bore to slide directly onto standard 3/16-inch (0.1875 in) diameter tool mandrels from Redding and other matching case preparation systems.
  • Stainless Steel Construction: Precision CNC-machined from stainless steel for wear resistance and dimensional stability across high-volume brass sorting sessions.
  • Brass Sorting Accuracy: Enables precision handloaders to accurately identify and separate cases exhibiting neck-wall runout exceeding 0.0015 inches.

Who is the Redding Case Neck Gauge Pilot Stop .30 Calibre for?

  • Precision handloaders sorting .30-calibre brass — requires this reloading case neck gauge pilot stop to maintain concentric alignment over a 3/16-inch (0.1875 in) mandrel while identifying neck-wall thickness variations exceeding 0.0015 inches across .30-calibre (7.62 mm) casings.
  • PRS competitors loading .308 Winchester and .300 Winchester Magnum — utilizes the undercut profile on this pilot stop to eliminate measurement drag at the case shoulder junction when inspecting 7.62 mm neck uniformity on standard 3/16-inch gauge shafts.
  • Hunters preparing extreme-long-range .300 PRC ammunition — relies on the 0.1875-inch mandrel fitment to set positive, repeatable stop depths during internal flash-hole deburring on .30-calibre magnum cases.

Less suitable for: Handloaders processing non-.30-calibre brass (such as .22, 6mm, 6.5mm, 7mm, or .338) or cartridges with small 0.060-inch flash holes requiring a smaller 9/64-inch mandrel; these applications require a dedicated calibre-matched pilot stop or a small-mandrel pilot stop bushing.
