No photos handy but get an old coffee cafetiere and rig up a means up suspending it in the bath.

Put some ordinary water in the bath and your cleaning solution in the cafetiere with your cases stood up on their bases.

This is efficient in terms of solution use and also lets you visually check when the primer pockets are clean.

I find that once they are clean the rest of the brass is usually done.

done

Hi - I normally clean 50 cases at a time. Will a 3KG machine be enough ?

I honestly don't know, but I wouldn't want one half the size of mine

After reading this thread, I ended up buying one of these:

Will take 100-150+ cases easily, and came with a couple of bags of 3mm steel shot, two spare drive belts and two O rings for the lid seal.
Add a flat teaspoon of citric acid, a dollop of washer liquid (I found non-bio washing machine stuff works better that Fairy.....), a litre of warm water, speed no 4, set 60mins, and off you go.
The 3mm shot works fine and is easy to recover with a magnet wrapped in a bit of cloth. It leaves a ring around the base of the primer pocket, though, so 2mm would be better.
