Nothing wrong with that. I like the oddballs myself, 6.5x55, 257 Roberts, 307 Winchester, 35 Whelen. With the velocities that you'll get from the 264 I'd say don't discount the standard cup and core bullets like the Hornady interlok, or SST. I haven't shot any of the Nosler 6.5's but have shot loads of Hornady and Sierra. What kind of hunting ranges are you looking at. I'd imagine a 140 would be just about perfect for anything but the big bears. The Interbonds and Accubonds or Partitions would provide better weight retention, from what I've heard from most say the interbond retains more weight but is more finicky on loading. The accubond is as accurate as a ballistic tip and give the same type of weight retention and penetration as the partition. Ultimately it's the gun that will make the decision.
