Kiwi--Whenever I bust out a new "lot" of .44 brass from my giant box of Starline, I spritz a little case lube (regular wet spray, non-aerosol) on a paper towel, and then wipe five or six cases out of 50 with the lube'd towel. I let the cases dry, and use one for the first round. When the press starts slowing, I use another lube'd case. Generally I have a couple left over when I'm done with the box.
