My method is to dump spent brass from the ziplick bag, or MTM ammo box into a 15"x15"x6" cardboard box. I do 250-500 cases (308ish size) at a time. I squirt about a tablespoon or so ivory liquid dish soap in there, then knead the cases with my hands for a minute. Then I shake the box around for a minute. I let the soap "dry" to a wax-like sheen for about 10 minutes.
Then I dump them into the case feeder of my 650.
The tool head is configured:
Station 1: Lee universal decapper
Station 2: Empty
Station 3: Forster FLS die - no decapping stem or expander ball
Station 4: Sinclair expander die with "neck turning mandrel" (.002" under bullet diameter)
Station 5: empty
They get dumped into the stainless and run ~1hr, get strained via an RCBS separator, towel dried as if polishing a bowling ball, then dumped in a 50 calammo can fitted with a wire mesh rack above a 100W lightbulb (had to stock up on these).
Next the cases get trimmed via Giraud. Then dumped back into the case feeder to be loaded.
