The Redding 06100 Universal Flash Hole Deburring Tool with .30 Cal Pilot Stop is a dedicated handheld case-preparation tool engineered to remove the internal manufacturing burr from cartridge flash holes. By cutting away the rough edge left inside the cartridge case during primer pocket punching, the tool facilitates unobstructed flame travel from the primer to the powder charge for more consistent pressure curves. It operates via a 3/16-inch hardened steel cutter mandrel fitted into an ergonomic Redding accessory handle, featuring an integrated web-indexing depth stop that prevents over-cutting the case head.

Key Features

• Internal Burr Removal: Cuts away residual brass around the flash hole in a one-time operation per cartridge case lifespan, promoting uniform ignition.
• Integrated Depth Stop: Built-in shoulder stop indexes against the internal web of the case head to prevent excessive brass removal or thinning.
• Chip Relief Port: Cross-drilled port on the cutting head allows removed brass shavings to clear smoothly during use.
• Calibre-Specific Centring: Supplied with a dedicated .30 calibre pilot stop collar featuring a set screw to maintain precise axial alignment inside the case neck.
• Manual Operation: Fully mechanical handheld tool requiring no electricity, cords, or external power sources.

Who is the Redding Universal Flash Hole Deburring Tool with .30 Cal Pilot Stop for?

• Precision rifle handloaders — who require consistent internal case prep on .30 calibre cartridges using the supplied .30 calibre pilot stop collar and 3/16-inch steel shaft to ensure uniform ignition flame travel.
• Benchrest shooters — who tune standard .080-inch flash holes using this universal flash hole deburring tool to eliminate ignition inconsistencies and minimise shot-to-shot pressure curve variations.

Less suitable for: Handloaders prepping cases with small .060-inch flash holes (such as 6mm BR, 6.5 Lapua, or PPC brass) or sub-.22 calibre brass (.17 and .20 calibre), which require a specialised small-diameter flash hole deburring tool (such as Redding Part #06110), as well as handloaders prepping .22 to .338 calibres other than .30 calibre without purchasing additional calibre-specific pilot stop collars.
