If I have my perfect powder measure tied up on a long run like .223 for example, I'll use my dipper set and scale to throw powder for a shorter run.
This week I wanted to load a few .45 Colt, so out came the scale and the dipper set. Just so we are clear, don't use the dipper without the scale. The powder dipper info they send with the kits tends to be conservative, but powder weights can vary enough to make big problems. Get a scale and use it, if you want to dip powder. Otherwise loads can be too light to cycle, or too hot to extract, or worse. Either condition can be dangerous.
