Currently, there is no system to deprime berdan cases. These are cases that instead of a single flash hole at the bottom of the case, there are two. This results in the decapper of the sizing die attempting to punch out an area of the case where no hole exists. Since the small flash holes are side by side, the decapping pin finds it's way to one or the other and most often will break because it is no longer centered with the expander plug.
