I dry tumble sometimes but only after depriming and SS wet tumbling, and my goal is to reduce tarnish but also I found it really helps prevent powder funnel stick. I don't like the One Shot aerosol on general health principles, but it certainly works and leaves no real residue on the cases. But...if I can 'dry tumble lube' cases en masse and prevent tarnish at the same time, I'd be happy.
Even with prolonged separating in my Dillon separator, I get retained dust inside cases from this media I bought at Dillon. This Dillon corn is pretty finely grained. Since the primers are long gone and the pockets are squeaky clean, I've taken to blasting the cases a dozen at a time with an air compressor just out on my driveway. Works, but takes too much time, tho, and I wondered, since I'm using this to prevent tarnish and to lube the cases to prevent powder funnel stick, maybe there's a coarser grain size that would have less dust retention?
My goals as always are to have as many cases processed in as short at time as possible.
Since my dry tumbling is NOT to clean the cases, but more to act like a tiny NuFinish applicator to every square millimeter of case surface, I even wondered about using polymer media but have zero insight into that. Corn is cheap and plentiful, so I can stick with that.... but would like less dust. Coarser grain?
Walnut alters the sheen of the case, not in a bad way, just different. But it is harder and seems less absorbent and I don't know if it's as good an applicator of NuFish as corn would be....
Thanks for any insight and/or experience.
