Small dippers or charge cups do as well as most commercial powder measures, as long as you use a consistent method for measuring the powder.
I use a small rice bowl, coffee cup or baby food jar to hold the powder, then lower the dipper slowly into the powder, letting it flow into the dipper of oits own weight, then raising it up and striking the charge off level using a card or pen knife.
Most problems with lack of uniformity in using dippers is cause by running the dipper through the powder like a shovel and trying to see how much you can get into it, causing varying amounts of compression of the powder, which is NO GOOD!
If you want a dedicated measure to meter small amounts of fast-burning pistol powder for cartridges like the .32 ACP and .380 ACP, the RCBS Little Dandy works well:
The RCBS Little Dandy measure uses interchangeable, drums or rotors to throw a fixed powder charge. The proper drum is selected in accordance with a table, which lists the nominal charge weight thrown by each numbered rotor, using various powders. Selection of the proper drum or rotor should always be done by consulting current published sources of load data. You should then check the charge weight of YOUR drum against a reliable powder scale. I drop TEN charges onto the scale pan and mentally move the decimal.
The rotors or drums are usually spot-on to the stated charge weight, or not more than 0.1 grain under. I have never found one which threw more than its stated charge weight. I use the Little Dandy in multiple applications, so I therefore, I post this charge table in my loading area:
These are the rotors I use with my RCBS Little Dandy powder measure and the loads they are used for:
