Like everyone else has said, every rifle is different, even rifles of the same make and model. What make / model 7mm-08 do you have?
At any rate, below is a link to Able Ammo which list 15 different 7mm-08 factory ammo offerings.

I've got a Remington Mountian LSS in 7mm-08. I handload so I haven't tried any on the factory ammo; however, in my gun the 140 Sierra Game Kings and the 140 Nosler Accubonds have proved to be the most accurate.
You didn't say what you would be hunting at +150 Yds. Accuracy is one thing, but matching the bullet to the game you are hunting is equally important (if not more so).
