From everything I've heard regarding the Lee Safety scale rwsmith's assessment is pretty right on. And honestly for all the talk regarding different powders and their relative safety and ability to fill the case, it's a lot like discussing which streets are safest to cross with our eyes closed. Please buy a scale. Even the little Lee scale can keep you safe and allow you to use the most efficient and cost effective powders for your task. With a new price between 25 and 30 bucks it is a bargain.
