I recently received the Lee Anniversary Kit as a birthday present, and today I actually got a chance to put together some ammo for my .223. I set up my scale, made the calculations to convert the powder measure from grains to CCs, and began putting powder into my scale tray from my measure. The first load of powder I made ended up light. So, I dumped it back into the powder bottle, and measured out another one. Same thing - too light. I did this about 10 times, and had the same result each time. So, I checked my math again, and everything was done right. I checked to make sure the scale was balanced, and it was. I checked to see if there was an obstruction in the powder tube, and there was nothing. So, I tried again, and had the same results. I ended up loading the shells using the powder dipper and scale. I only loaded 5 shells, so it wasn't a huge deal. However, when I want to load 50 shells, I will most likely not want to do this again. Is there some basic rookie mistake I am making here? Is it likely an error with the measure, or with the scale? Should I contact Lee? Any advice on the matter is appreciated.
