If you got the Tikka T3 lite with the Burris scope for $599.00 then you got a screaming deal. I bought the same setup as you but in 270 win. And I love it !!! I load my own ammo. I would buy either the Barnes or Winchester ballistic silver tip. Dicks sells the Barns. Their the best IMO.
As for the Burris scope. It's great. It does it's job. I will re scope my rifle next year and will use Talley scope rings.
