They aren't hard to use.
As I recall, my BBB scoop holds 68? pellets for a one ounce load. 8x8 matrix, and a row of 4. Used a 3/16 bit as I recall.
Easy Peasy goose loads.
I just dump shot into a plastic storage bowl, and scoop, shake, and check all the holes are filled.
I could probably go hi tech and stick magnet strips on the back side, but plain holes work just fine.
When you start getting into small shot, using a half scoop makes getting every hole filled a little easier. For #6 as example. There's like 320. So, 160 holes is way less work.
It's funny how the more things change
, the more they are the same.
