I only have a vibratory tumbler and I don't want to buy more equipment (ultrasonic or rotary) What I've read it takes rotary for the stainless pins to be use?
I've concluded that the 2 posts above are about the right approach. Soak until color change (and no longer) then polish.
I bought the little drill chuck shell holder (2 pcs) Lee makes so the polishing will be quick.
I still wonder a bit about the brass because both sides of the case walls have been tarnished and then zinc depleted. Have to just try it out carefully and see what happens.
Seems like I've found yet another new hobby - brass recovery & rehabilitation.
