Ran 100 308 cases through it to load up some new deer rounds because I only have 3 left. Water and lemishine to polish it. Had to wipe the grime off all the cases after I pulled them out. Did I miss something, or is this normal for a wet tumbler. I got the smaller FA rotary tumbler, and it is the first time I've used it. Brass looks good after I wiped em all down though. Letting them air dry now to get any remaining water out of the insides before I prime. Good way to kill most of a semi rainy Sunday afternoon.
