I use an autodisk on my Dillon 550B for both .45 and 9mm. I use Unique, Clays, and WW231. The Lee measure works well for all of these powders but I can't address Bullseye since I've never used it. With the 231 the autodisk drops within a 0.1-0.2 grain variance which seems good enough. I like it better than the Dillon measure.
