Then there are those of us who always tumble/clean our brass before reloading.
Are you suggesting I don't clean my brass? If you are,then you don't know what you are talking about.
When you clean the grti off your brass in the tumbler,where does the grit go?
Do you change your media after every use?
My brass never strikes the ground. I shoot from inside a "shooting shed" that has the right side modified with a swing-out 4x8 panel that holds a blue tarp pouch to catch all auto casings.
The majority of my shooting is revolver (K38), and the empty cases are dumped directly into a plastic freezer container where they stay until dumped into my Frankfort Arms tumbler, walnut media.
So in neither case, does any of my brass pick up "grit" from the ground, therefore the tumbling is only to remove carbon and any bullet lube (using up the very last of bullets NOT lubed via powder coat), that happens to be on the cases. Given that my cases never hit the ground in the first place, your questions are moot in that there is no "grit" on them in the first place.
