Most any 180 grain bullet is going to work well in this caliber. The Hornady Interlock has a solid reputation going back many years for good large game performance in the 30/06. And don't cost a lot either. 180Partition is tough to beat as well - if you want to spend twice as much. Premium bullets, while a virtual necessity in the big magnums, are not needed at 2600 fps. Even a regular old Remington Corelokt will work like gangbusters.
