I obtain relatively consistent charges (well w/in + or - 0.01 grains) with small amount of (5.7 grains) of 231. I found that keeping the power measure about 3/4 full aids in consistent charges. Also, I condition the measure with 12 throws before discharging into the case. I spot check every 10th discharge and they are almost always spot on. Also, I tap the measure front, back, and sides to settle powder before conditioning the measure as described above.Not really, it promotes more consistent charges and stops bridging of the powder, especially with small charges.
