Unique is the first powder I purchased when I started reloading quite a long time ago. At that time I bought the RCBS Uniflow with both large and small drums. I do not ever recall using the large metering drum. Many suggested that a uniform movement of the lever making positive contact with the stop at each end of the movement could lead to more uniform metering. There were also baffle plates that could be inserted in the plastic tube holding the powder. Instead of installing a baffle, I fabricated a funnel that was about 2" short of reaching the level of the casting. In use, this seems to provide a uniform powder column to feed into the metering chamber. My needs are not critical, but consistent measurement seems a good idea.
My next most used powder measure is the old Bonanza Bullseye measure. It had not had the greatest of care and the set screw that was supposed to enter a hole in the red funnel had not been used so the opening at the base was badly distorted. Tight budget forced me to modify a plastic piece to just fit on the top of the metal body and secure with epoxy so the powder movement was straight down into the metering cylinder. Starting at nearly full, and moved independently to fill a loading block of primed cases, always left me sufficient powder in the cylinder to result in decent consistent results.
Low pressure charges result in a lot of unburned powder flakes but that is a use issue, not a powder issue.
