Hornady came out with the .277/145 grain ELD-X for the 270. Supposed to stabilize in a 10 twist, and has an excellent BC for that caliber. I have been shooting the 140 Nosler out past 1000 in my sons 270, but recently bought some of the 145 ELD to try. Just haven't gotten around to loading them up. Friend of mine shoots the 115 Berger in his std twist 25-06.
