WD-40. I spray a little on my case lube pad and roll the cases over it. I also spray the head of a Q-tip with WD-40 and swab the inside of the case neck very lightly. I've been doing it this way for about 7 or 8 years with great results.
My reloading is done in a room in the house. My wife would run me off because of the stink of that WD-40. Too bad, sounds inexpensive.
