Powder measures work great. Just be sure to weigh your charges about every 5 loads or so to make sure that that the powder measure is holding it's setting. Once I get about the first 15-20 loads or so and I know that the powder measure is holding it's setting, then I will sometimes only weight about every 9 or 10 charges. For target and test loads sometimes I will use a dipper and the scale though since those loads are not as important as hunting and precision shooting. I myself have found that loading with a dipper gives me pretty good overall accuracy, and its generally pretty quick to load with one. For large batches of shells, say from 50-100 loads it is worth it to take the time to set up the powder measure.
