I am a big fan of the 7-08. Been shooting it since the early 2000s.
I agree with Castle that if you are a 300 and in hunter, the 120 grain NBT is a fantastic bullet. The 162s are good, but you can run out of room in the case really quickly if you have mag or chamber restrictions that are going to limit you to around 2.800" OAL. If that is the case, the 150 grain ELD-X bullets are a very good compromise. They will perform out to the outer limits of the 7-08s ability.
Congrats on the new rifle. I look forward to seeing how it performs.
