We produce an undersized flash hole decapping pin for both the ACP/APP decapping kit and Universal Decapping die.
The decapping pin on the standard decapping rod of the die is .062" in diameter, which is the standard flash hole diameter of most ammunition cases made both in the United States and foreign countries.
The undersized flash hole .03" could be enlarged with one of the commercial flash hole uniformers or use a 1/16 (1.6mm) drill.
