i would either go accubond or partitioner. I think that the highest grain you can shoot out of a 270 off the shelf is a 150, so i'd probably go with that. Federal has the Nosler Accubonds in a 140 grain and the Nosler Partitioners in a 150. I believe Guy was shooting a 270 on that Nevada elk hunt they aired this season and took that bull at like 400 yards if i remember correctly. Good gun, i was recently in the market for a new rifle and was torn between the 270 and the 30-06. I ended up with a 30-06 just because of the more variety of grains you can shoot out of it, but i've seen some impressive shots with a 270. Good luck!
