I think the first way to go for reloading newbe's is to learn with the directions in one manual first. Do that and you'll learn to make safe loads and probably be some good ones too. Then once your really comfortable start looking for ways to tune your loads if you like. I found when I started that doing it the mundane way gave me good hunting accuracy, like all my rifles got down to 1" @ 100yds or better. I don't do near the tuning other do and today I have several 1/2" rifles. The tuning improve's usually just a bit at a time. But, learn to make good safe loads before you start much experimenting. Always nice to have some sort of reference for what your doing.
By the way, I said use one manual to start. Reason for that is they all say pretty much the same thing but in different ways. Learn one way to start!
