It's just they way I grew up and was a lot more necessary back then. Habits keep you safe. Habits die hard. The best I've been able to do breaking habits like this is to charges cases directly out of the measure and only weigh every tenth one when I am doing a bunch like .223s. Any deer hunting loads or anything less than maybe 100 rounds are 100% weighed and trickled up to weight. That was just dogma in the church I grew up in. Knowing it's safe and that the measures are all very consistent will never override the training and habit.
