Lee Undersized Flash Hole Decapping Mandrel .3055 Diameter (300 AAC Blackout)

The Lee Undersized Flash Hole Decapping Mandrel was designed for some foreign made cartridge cases that have a flash hole of .050" or less. This is smaller than the diameter of the 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. This undersized pin will solve these issues.
