Getting to be a lot of match bullets for the .277 (.270-6.8). I haven't gone to the new 6.8s but I've started taking advantage of the better bullets for my .270 Winchester.
Don't have to go to high price bullets to make your 270 a long range round either, Berger, Hornady, and others have reasonably priced highly accurate bullets.
This makes an outstanding round even better. They even have 165-175 super high BC out for the 270 if one adds a faster twist if one wants to go that route.
As for the newer or shorter bullets, I'm not sure they add much advantage to the 264/6.5 rounds.
