Clearly, your powder measure is not working well enough with Blue Dot. When I use the Dillon I generally use a powder that meters well, like VV3n37, AA7, or very small flake powders like WW231.
I'd call the UniqueTek people and Dillon to see if there is a better way to use their product with med-to-large flake powders. If there isn't a solution, then you really need to grab a different powder.
