I'm in the hunt for a new rifle...
I'd go t3x in 308 all the way. Or 7mm-08 is a great underestimated round. My buddy just got one and it's fantastic. Shoots 1/2 all day long.
The other option you should seriously check out are the new Kimber hunting rifles. They are very well made, accurate and lightweight. And contrary to what the internet says, I have yet to see one that didn't shoot under 1in, with most being 1/2 or better.
