My personal advice is to find a local CMP-affiliated club, and a range that holds some matches. Then, when you get the thing, shoot in those matches as often as possible. They are fun, good at developing or improving form and every match I've ever shot has been attended by friendly interesting people.
Think about it. You get a cool old rifle, the chance to shoot it a lot, and the opportunity to hang out with people like you. How can it get any better!
