The last time I ran out I robbed the mink oil out of my shoe shine box, works great for finger lubing.
Lately, in this climate, I've been having to size more already primed brass so I use lee water base lube, put a peanut size dab in a 2-quart plastic container with a lid, fill 2/3 with brass and shake until all have a light haze. when done sizing, I roll the brass on a rag dampened with water and a drop of dish soap, then on a towel --- good to go
