I load a number of cases that use very small amounts of powder (1.5 up to just less than 3 grains each). Doing them with powder drops is more time consuming than I like and the accuracy is questionable with amounts that small.
I have a couple of sets of Lee scoops (and have used them for years), but they were never exactly the right size. I made several scoops from fired .22LR cases. They worked well. And, once you get some practice, they are very repeatable, too. Finding the right length was time consuming, though.
Here is a chart I made for shortening .22LR cases for use with Bullseye powder (that is what I usually use with very small loads). The four dots are the actual cases I made for different amounts (and I checked them several times for accuracy). The dotted line to the right was put in by the computer. I extended the line to the left to make sure it came out on the zero/zero intersection. It did. Also shown is one of the completed scoops.
I cut the case just a little longer than what is predicted, then solder a handle on, then test it. Make small adjustments with a fine file.
