The new Barret 98Bravo looks interesting. Take a look at the Blaser LRS-2 Tactical (I think that's the current designation). I had one in .308 and it was amazingly accurate, I came close to getting the .338 in it's place but decided to build an M14/M1A instead. The Blaser was very easy to load for, it seemed to shoot any quality load well.

Although I wouldn't buy a new one, the Dakota Longbow had a pretty good reputation, last year there seemed to be a number of them for sale on gunsamerica. On the hunting rifle side of things, I saw a Dakota Traveler that had .338 Lapaua and .416 Rigby barrels on gunbroker a few months ago (since sold), that would have been a pretty nice setup.
