I buy & sell a lot of range brass. After separating the brass I'll run it through the Frankford for 45 minutes to get all the curde off the cases.
My personal brass gets deprimed then tumbled. The cases are 100% clean inside & out. The primer pockets are always 100% clean.
Does the brass need to be that clean?
No, but if you are going to tumble your brass why not make it cllok the best it can. Like new or better then new.
Every one adventually has their way of doing it. What works for some people doesn't work for others.
I have two of the larger Frankford wet tumblers and use the pins that came with them. I did buy an extra five pound box of pins which just sit on a shelf.
No matter how careful you are you are going to find pins in places that you never would of imagined they could of got there.
I made & use case drying racks to dry my brass.
Never tried useing a electric dehydrator, the way I look at it Ship runs down hill, payday is on Friday and never chew your finger nails.
Gravity is your best friend. Damp cases will always misfire. Hanging upside down everything drains out.
