First figure out what position and equipment you are going to use to shoot that rifle most often, then zero the rifle for that position. Second figure out what kind of shooting you are going to be doing most often (hunting, tactical comp, bench rest comp, across the course, long range NRA, silhouette, etc.) and get yourself to a good instructor to teach you how to shoot that discipline safely and accurately. If you don't have the money for the instruction, put the rifle away and save up the money until you can pay for the training including 500 rounds of good ammunition.
