everyday pick a thread that you nothing about and go find the answer
that might sound stupid but it your way to learn
you don't need to post that is not the goal
how does this help you
say you see a rifle or pistol you would like and you know nothing about it so you look for a parts diagram and then parts and availability and cost and after that you may have changed your mine because there are no parts and next time you see one for sale you know to walk on by
and if you do this for 10-15 years you will have a general grasp of where you can find answers, where to find parts, where to find info
now a Blue Book is a great source of info but they have stopped printing new ones
learn about what you have, what you want and things you will never have it is like a million-piece puzzle and you are finding and placing one piece at a time
will you always find the answer NO then you will learn from a forum member that knows and posts to the thread
shooting, tinkering and learning are part of this hobby and read more than one forum
