These two gave you some good advice.

I will just add that when you visit a gunsmiths shop look around and see if it is clean and orderly or a mess of crap laying everywhere. The one that keeps everything orderly where he knows where everything is will usually be the one that will pay better attention to your firearm and will likley give better service. Try to see how he takes care of his machinery like lathes and mills. If he takes care of his stuff odds are he will take care of yours.

AS far as accuracy questions....... there are a bunch of things you can do to different firearms that should make them perform much better than out of the box. You will get better answers if you ask more specific questions.
