Until you do get into reloading, look for some Federal Gold Medal Match 168gr or Hornady or Sellier Bellot or if you get real lucky Lake City Match, none of which will be cheap. Hence the advice to reload. But as others have pointed out and as you will find, different rifles prefer different loads.
Save all of your brass (doh!) and spend some serious time in the handloading/reloading forum reading and learning.
ABCs of Reloading is your introductory primer as hooligan pointed out.
Scroll down to find other books from different mfgs.
Oh yeah, welcome to TFL by the way.
