I use the Dillon brand lube and it takes just a tiny spray....I usually lay the number of cases out I plan on loading, spritz, roll with a sponge, load, check and gauge the rounds. Then, I lay 'em out, sprits with cleaner, roll, put in a case. I usually do about 20 at a time this way with powder checks at 1, 3, 10, and 20.
