Re: Why doesn't my Dillon 550B meter consistant weights?
Here's what I do. After setting up the powder measure for case length, I fill it with my intended powder, them tap the side of the reservoir sevral time with a plastic screwdriver handle before setting my charge weight. I used to have a lot of trouble with inconsistent charge weights until I realized that my powder charge was getting heavier as I loaded. Since the whole powder measure moves on the 550, I feel that the constant cycling was causing the powder to settle in the reservoir, essentially making the powder charge more dense with each cycle. The type of powder used has a big effect on this too, dense, fine-grained powders like TAC meter more consistently for me than say, IMR4895.
