I just received my adjustable rotor the other day- I hope Bill White can get back into full production. The rotor is a real work of art. I have all of the Little Dandy rotors, have been using then as my main pistol measure for probably 20 years. I bought the adjustable one to be able to use loads that the rotors can't do- the intermediate loads. The adj. one doesn't do anything different than any regular powder measure, it just does it on a smaller scale- sort of like using the smaller pistol measure on the RCBS full-size powder measure. As for a baffle- just stick a funnel on top with a small tip inside the Little Dandy- the funnel regulates the powder level.
