KM Flash Hole Uniformer – 20 cal
The KM flash hole uniformer is a specific unit for the 20 caliber (eg: 204 R). The shaft is slightly undersize for 20cal.
It is made with depth control on the case web so the pilot cuts the flash holes to uniform size and also cuts a depth controlled slight taper on the inside to remove burrs.
This is for the standard 20cal flash hole size being 0.080″.
For some “Wildcat” cartridges like a 20cal PPC based on the Lapua 220 Russian case, which have smaller flash holes, this tool will not be the correct size
