Thank you! Thank you very much!
A couple of footnotes:
A longer straw can serve usefully as a drop tube for some loads, increasing possible amounts of powder that can be trickled into a case. Occasionally one can find two straws that have a tight telescopic fit, one inside the other, which can serve as an extensible drop tube. A small piece of masking tape can stabilize the extension if needed.
When the case mouth is larger and a straw cannot be found to fit around the neck, a smaller diameter straw can be found to fit inside the case mouth. Several layers of tape may be wrapped around the straw as a sleeve set back a bit from the end of the straw, with the case mount supporting the tape sleeve as powder is poured into the funnel on top of the straw.
