Undersized Flash Holes

Undersized Flash Holes

It has come to our attention that some foreign made cartridge cases have a flash hole of .050" or less. This is smaller than the diameter of our standard depriming pin, and consequently, if one tries to deprime/resize these cartridge cases, the depriming pin will get stuck and/or get pulled out of the expander. Our recommendation is to drill the flash holes to a uniform diameter with a 1/16" or a #52 drill. Most domestically manufactured cartridges are made with the SAAMI standard flash hole diameter of .062" and are not a problem.
