You are Gunna want a caliber that will absolutely burn the ever living fuck out of a barrel because talking about how bad ass your gun is while it is away at the smith is a lot more fun than actually shooting. 6.5 wsm would be a good one.
Just kidding. Welcome to the hide. I had really good luck out of a Remington 700 5r in 308. Good gun decent stock and a lot of aftermarket support.
The Remington 700 SPS Tactical in .308 is a decent gun for the money. .308 is cheap and easy to come by. By the time you wear out that barrel, you'll have a really good feel for what you really want in a rifle and can upgrade what you already have.
