A friend bought me Hornady case sizing lube item #050009. I put a bunch of brass in an ice cream bucket, 3 or 4 drops of the lube, and swirl and toss the brass inside with the lid on. All the brass has a very light film, and I did 250 308 brass at once that way, then another 200 right afterwords. The good part is not one neck got dented from too much lube, bad part is the inside of the neck is still dry and would hang up. So I dip the odd neck in some lee paste type lube I have kicking around and wipe off whatever got on the outside, and run it through. It keeps the expander ball lubed for 15 or so cases. Took me about an hour to do all 450 brass on a single stage like this.
