Been using the 7mm-08 for a long long time now and for the lighter bullets I agree the 120gr Ballistic tips shoot really good and the Sierra 120gr Prohunters as well. The 120gr Ballistic Tip is the bullet that shoots best in my wife's rifle, 0.20" groups.
The Sierra 100gr Varmints are also very accurate, under quarter MOA groups as well.
Mine likes the139gr SST better and Interlocks too.
On both rifles140gr Sierra Gamekings and Prohunters shoot cloverleaf groups as well. 140gr Accubonds also shoot great under half MOA. I have not tried any 130gr bullets in a while.
On the heavier side the 150gr Sierra Matchkings with IMR-4350 are crazy accurate, I use these for Silhouette competition.
Several 160gr and 162gr bulleta also shoot really good on both rifles.
