Not to inject another variable into the mix, but 150 grains is not a standard weight for the .38 special. That may be the reason you aren't finding much load data for it. If I were to guess, I'd say those bullets were for a .38 SUPER, which is a round for a semiauto pistol. In that case, the diameter is off, too, so you may never get consistent accuracy in your 38.
You might be happier and less frustrated by getting the correct bullets to start with. That way, there won't be so much of a "fudge factor" at each step, and you will be able to figure out why each step is the way it is. Lots of good advice here, and you're off to a good start by asking questions. Good luck!
