Powder Cavity Tolerances

The powder manufacturers allow themselves a 16% tolerance in the density of their powder, from lot to lot. Lee has to calibrate their chart to show the high side of that tolerance, so you should never get more than what the chart indicates, but you will sometimes get less. Believe the scale. If your measure consistently throws less than what the chart indicates, try going up to the next larger cavity. If the powder measure throws more than what the chart indicates, please let Lee know!
