For the pins, one one side i put the collator cap and shake all the water and pins into a big bucket, then i add more water shake it and drop all the pins and the new water into the bucket, i do t his maybe like 5 ot 6 times shaking it very vigorously until the water comes out clean and almost no pins come out.
At this point i have like 95% of the pins out, i remove all the pins and water from the bucket and i drop all the shells in this bucket and fill it with water, I stir it with my hand, any pins still inside shells should drop and stay at the bottom of the bucket, i remove the shells with my hands and lay them on a plastic tray, where i use the magnet to pass on top of them and pick up any pins left.
Finally i pass the magnet again over top of the shell been very careful to not touch the shells, and i listen to see if i hear any pins moving inside shells. When i dont hear anything im pretty confident i removed 99.9% of the pins.
I hope this helps.
Happy reloading!
