This 380 ACP adapter plate allows reloaders to easily separate 380 ACP and small brass from 9mm Luger. To use this plate, sort all of your brass as normally through the Shell SorterTM 3pc set. The contents of the black pan will contain 9mm and 380 brass. Set the 380 plate inside either the blue or yellow Shell SorterTM pan. Sort the contents of the black pan through the plate, 380 will fall through both the plate as well as the blue or yellow pan, 9mm remains on top. Do not use the black pan with the 380 plate as the 380 brass will get trapped between the plate and the black pan, where you will frequently need to remove the plate to get the brass out.
