You get a double education in one of several ways. You buy guns and take a beating until you learn what to buy and why. You buy books and magazines and spend many very enjoyable hours reading about guns you wish you owned but most likely never will, while you narrow your interest down to what you like to have and go from there. Or you come to a board like this and learn as you go.
This board use to be much better for information exchange than it is now. Too much politics, too many acidic personalities, too many personal attacks distract from it's real purpose of information exchange about doubles. Too many trolls and people with personal agendas ruin most of the threads. There are some great sources of information and if you see a post by Researcher you should read it even if it does not directly concern a point of interest. His post are stocked with vast amounts of well reasoned and correct research which give you vast amounts of information and also can give you a general background knowledge base which is useful
The Rifle portion is still very good as the vitriol seems to not be as likely to invade every thread. Even the For Sale sections can degenerate into a mess on some post. But don't give up there is still more value here than first meets the eye. If you bring a good question someone most likely has the answer if you can just get through the background noise.
