After the recent demise of Kim and Connie's site, I was saddened to see the Nation of Riflemen forum go with them. Well have no fear, it has returned under new management.
Why do I mention it? Most of my readers aren't gunnies, but recent experience has shown that a few of you might like to start. Well if you are interested in guns, the NoR forums has excellent beginners sections. I normally shoot shotgun and a lot of pistol, but I am still learning the basics of riflecraft. NoR has taught me a lot of very important fundamentals like shooting positions.
Other forums like The High Road and more weapon specific forums like 1911forums will be of more use once you get farther up the learning curve.
