Fecmech: OK, thanks for the help, but I'm looking for specific information for this particular powder measure, which doesn't use bushings, but an adjustable micrometer. I'm aware of the differences between promo & red dot. If you are loading properly with this powder measure, you have to calibrate by the individual container of powder, then mark the bottle/can/jug. Appreciate the warning, but need help with whether or not powder will stick/meter correctly.
Jay: Thanks. Do you have any experience loading with red dot or promo with this measure? I'm worried about using a flake powder with a low charge weight.
