Do not trust the dippers. They weigh differently with every powder. Select a load that you are going to use then try the dippers. Take 10 dips in a scale tray and then weigh it and get an average to see what they are throwing with THAT powder. Also. To get consistent loads from the dipper, Pour excess powder in a bowl then dip through the powder and then use a straight edge to cut off the top of the dipper so you get a level dipper each time. I use the straight edge on my powder funnel.
What I'm getting at, is, that for the load that you want, it may not be the AVERAGE dipper on the Lee chart. Sometimes I use a different dipper to get the load I WANT. Also, to get the in betweens, I sometimes use two of a smaller dipper. You sometimes have to use some common sense and experiment. I have an expedient kit with hand press, dies, dippers all necessary items in a clear plastic dog food bucket that goes in my truck when I go out for a while. You can make them work.
