With a set of dippers & a dipper capacity chart that cross references the different powders & weights for the different cc dippers you can cross reference powders not listed with load data from the bullet manufacturer, I can't seem to upload the Lee dipper capacity chart but it can be reached online. The dippers can be quite consistent if they are used the exact same way each time, letting the powder flow down into the dipper by keeping it upright and pushing it down into the powder letting the powder flow in rather than scooping it, and striking it level the same method every time.
