For me, I can set the drum on the auto throw to be within 2-3 grains of where I want to be using the numbers on the drum. Then I manually dump a charge from it, and take a powder scoop to trickle up to desired weight and set it. It takes like 40 seconds in total. Then the auto throw and auto trickler do everything from there. If I’m doing load dev, I just start at the lowest charge, then on the next I’ll manually trickle the auto trickler by hand to throw .2 more after it hits the target weight, reset the target weight, and repeat. It’s maybe 10 seconds per charge slower than when I used two chargemasters.
