Powder measures for Bullseye?

First topic message reminder :

Hi,

What powder measure do you use for Bullseye powder?  

I tried my old 3-slide Lyman.  The charges varied enough to string vertically at 50 yards.  The charge was 4.0 grains with a 185 gr cast SWC.  

I have several other powder measures.  I could even modify one of my RCBS units for a small diameter powder chamber.  I do not own a RCBS Little Dandy, do they work any better for this? 

Yes, I could use a ball powder.  Thing is, I have a bunch of Bullseye and would prefer to use it if I can given the powder supply realities today.  

Thanks,
Scot

Probably a couple hundred thousand rounds on a Star and not one problem.
