Hi...
I have used a Little Dandy for years for all of my reloading. I like it a lot...never goes out of adjustment and very consistent.
You may have to experiment with which rotor to use because the chart is seldom exact, depending on the powder and charge weight. If I can't find a rotor that will drop the exact charge I am looking for, I just use the one closest to that charge without going over and then trickle the balance in with an RCBS powder trickler. I can generally find a rotor that will drop within 1/10 of a grain, so for most handgun loads that is close enough since I do not load beyond recommended levels.
