Skip loading, as Gdawgs suggest. That's the classic exercise. I do it a lot. It also saves ammo, or extends your shooting day, depending on how you look at it. I like to load 2 - skip 1 - load 1 - skip 2.
I"ve also had people skip load 38s and 357s if they're a little afraid of the magnums. Unless you're using really light 38s, or really monster magnums, you always end up saying "Was that one the magnum or the 38?".
