I’m on my second BR-30, the first having gone to the kids. I have both the large and small drums. I’ve always gotten good results. In the past. I would, when using a new powder, take a piece of graph paper and label one axis with the micrometer settings and the other with charge weights in small increments, weigh a couple charges, one near the low end and one near the high, and plot a line through them. Then when I wanted to set it for a particular charge with that powder I could go to my chart for that powder and find the setting that would give me that weight or very, very close to it.
