Selmer,I do not load in volume. It just seems to me that I would spend more time filling, adjusting, and dumping back out than I do dipping and weighing. My time is of little value, and I have gotten fairly adept with my Lee dippers and my Ohaus 5-0-5 scale. It isn't for everyone, but it works well for me, and I would imagine for some others as well. Best, John
