I used to try self-hypnosis to astral project, but I've come to the conclusion it won't work.
Here's why: I can't spontaneously astral project, and astral projecting takes a lot of will power, or luck through lucid dreams. Even though I'm telling myself what to do, my astral body doesn't know how to accomplish it, or doesn't like taking orders. I *only think it might work* once you have had some successes with astral projecting consciously, and then only to increase the frequency. But, self-hypnosis and meditation have some similarities, so once you have a feel for what you are doing, you could replace the meditation with self-hypnosis (that is, if you meditate).
