I taught myself using a few reloading manuals the instructions that came with my Lee reloading equipment and, of course, some commonsense. Having said that, once you get started you will probably do more and more reading on the subject...... only some of this extra reading teaches you anything of real additional value, from what you learned at the start.
The Vihtavuori manual (and their powders) have proved particularly rewarding for me.
Being shown things by an "expert" would probably have speeded up the learning process, but since I've witnessed more than a few experts that proved to be grade1 a-holes I'd say you shouldn't worry about taking a bit of extra time to teach yourself, if you still can't figure out something maybe asking questions on here (for instance) is the way forward.
btw... it's not very hard to learn at all... I hope you enjoy it.
