Monty pretty much nailed it.
Good optics is the first item, and that will probably cost more than you paid for the rifle.
Then find the bullet it likes, start with those high end custom loads, they usually come closer to being more accurate.
A good trigger is critical, I like a 2 1/2 pound pull on my hunting rifles, but it has to be clean and smooth.
Then comes the stock, your next major expense. I'm not familiar with Savage stocks, since I've never owned one, but if its a good candidate for a proper bedding job, then I would look at that. If not, I would find a quality aftermarket and have it properly bedded. Please notice, I kept saying "properly bedded". Finding someone that can do that is a task in itself, and they are not going to be cheap. Most anybody can bed one, but to do it right, not many can do that.
It sure is nice when you see the transition on each phase of your build and the improvements each makes. Welcome to the site and Good Luck.
