I've shot them with .280AI/150NBT; 300WM/180NBT; 6.5/284/125PT & 120NBT; and the 6mm/284/90gr NBT. I think the 6.5 Creedmoor is an excellent choice, myself. From what I've seen of it, out here, it has become "like a Modern .257 Roberts" in the way it is used. Varmints to elk with targets thrown in too.
