It's no trick to get 2,650 with a 160 from the 7-08. That's essentially the same speed as a 180 from the 308. The last has taken so much game as to be indisputable in its effectiveness. It's what most 30-06 factory 180's get. I think the 7-08 has plenty of gas for a 160, and a Partition in that wieght at 2,650 turns the 7-08 into a giant killer.
