I like the mentor/apprentice concept, but if you are a novice, it is hard to choose a mentor who will steer you straight. I knew folks who, when they showed up at the range, had a fair chance of blowing up a gun. If they were having a good day, (defined by no blown guns) and a novice approached them, I have no doubt they would have taken him under their wing and had him blowing up guns in a matter of weeks!
There are a few folks on this site that advocate what I consider to be dangerous practices, and I expect they may, collectively, own a few "altered" firearms. YouTube scares the begeebers out of me. While it is a great place to find videos put together by major manufacturers, you may also get suckered in by a fairly knowedgable sounding idiot, who will coach you in how to do really unsafe things in the belief that since it hasn't backfired yet, it must be OK.
Handloading is dead safe. But, it does require being sober, attentive, and respectful of professional expertise. A couple of thousand dollars and a few thousand hours reading current (and archived) gun rags is also a good adjunct to the ABC's, a manual or two, and the manufacturers' videos. Enough of the rag writers are honest enough to eventually disclose quite a few of the least expected surprises the game may hold for the too adventurous. Thank god for modern steel!!
