The National Shooting Sport Foundation has lots of great video about shooting techniques and instruction. Keeping with excellent instruction is one about sighting in a rifle that most of us can do easily even as a noob shooter.
I've used this same technique sighting in my many bolt-action and semi-auto rifles. I do like the fact it shows bore sighting by literally looking down the bore of the rifle. It gets you on paper with no expensive tools or laser beams needed. Just a good set of eyes.
