you can probably save the money you'd spend on the video (and spend it on upgrades) and get most everything that you need in these forums. When the search function is up and going there is a lot of information here, until then ask what you are wondering about and you'll be answered.
...and don't be afraid to ask. The people who hang out on this website have a combined knowledge of more than you'll ever find in a book, but you need to ask.
Unless your question gets posted in the wee hours of the morning, it's seldom that you will have to wait long for the answers, and weekends tend to be a little slower, but unlike some other websites, it is totally unnecessary to make multiple postings of your question on different threads. Just ask it once on the appropriate thread. It WILL be seen.
(Of course, this is a cheap way of saying that, so far, no one has a good answer to your question)
I think a guy named Jeff Cooper has a book titled "The ultimate 10/22" or something similar, but I've never seen it.
I can't advise which is the best...I have only seen the AGI Ruger 10-22 armours manual....It is VERY BASIC as if you don't know anything about the gun.....for that information it is ok....they show some aftermarket parts and that is somewhat "dated"....the picture quality is similar to a home video and leaves a LOT to be desired for quality/clarity......The BOOK ...the Ulitmate Ruger 10-22 users guide by Mark White is very nice and has lots of good information........as the other post states you can get LOTS of good help and information here and the board can help you avoid mistakes that WE made trying to learn on our own or good tips to make working on the gun easier........the AGI video would be great for a rental fee but I bought it expecting a professional quality picture and content not a back yard prodution.......live and learn....good luck and good shooting!!!
