Shootist,
As I mentioned earlier on this thread, I've owned a Lee Dipper set for many years. Mostly I use it when working up loads, and found that if I tilt the dippers a certain amount I can come very close to the desired charge. Then I top it off with a trickler.
With finer-grained powders the dippers can work pretty darn well. In fact I found one of the smaller ones throws 13.0 grains of Li'l Gun, exactly what I use in the .22 Hornet with 40-grain bullets. That's just by burying the dipper in the powder and pulling it out upright.
