Harvey Deprimer is to be used only with discharged primers. If you have unfired primers that need to be removed, we recommend discharging the primers first with the proper firearm. If the primer cannot be discharged, we recommend disposing of the case in an appropriate manner. Safety glasses should also be worn for eye protection.
