I have no problem whatsoever with new shooters asking questions, and some of them have the wisdom to hear, consider, and act upon the advice those questions generate. An example would be (I think I remember it correctly) JDMorris (correct me if I am wrong) who, at a similar age had a lot of questions. When he began asking questions and had no clue about that which he was speaking, he was a tad cocky and argumentative. As he kept asking questions and started to realize the wisdom here, he grew immensely as a shooter (according to pictures he posted) and forum member (once he stopped recommending that everyone get a howa, and started posting thoughtful suggestions). I would advise that you take that route. I have read your other threads because I love customizing rifles, and it seems every time you start a thread it is in some new direction that shows no sense of direction other than an attempt to ignore any advice given. It's your money, do what you want, but why ask if you don't care about the answers given?
So, here's my answer to all of your threads, synthesized into one. You have seven hundreds, as you say, so use those. If you are like me and you can't leave things alone, then that's fine because making a rifle "yours" is fun, and for some of us, stock factory rifles are just boring. If that is the case, given your age and the likelihood that you don't have expensive and job specific tools lying around, then go savage because they are the easiest bolt rifles to re-barrel. A stevens 200 is a great action, and it is the savage 110/10 that has been the basis for a BUNCH of super-accurate rifles. Finally, given your age (again) and its accompanying fearlessness that boarders on insanity (I work with teenagers for a living, I know), Don't do a trigger job, or at least don't do it yourself.
No matter what you do, those who commented before me are right, nothing but shooting makes a shooter, and sometimes not even that. Perfect practice makes perfect.
There's my (long, sorry) answer. You can take it (doubtful) or leave it (probable).
