Before you shoot it, run a patch through the bore, make sure the action screws are tight and run a few thicknesses of paper down the barrel channel to see if the metal is too close to wood (if it's supposed to be free-floating).
Then, pick up several makes/weights of factory rounds to test the rifle with. Make sure you fire the rifle for groups from both front and rear rests at a bench.
Don't worry about the first couple of shots. Just shoot them at 25 yards to get a rough scope zero, then move to 100 and start getting a little more serious.
If I can't be with the rifle I love, I love the rifle I'm with!!
