I've got a couple of 7-08's and these work well in both:
140 Accubond- 42g Varget, OAL 2.803
45g IMR 4350, OAL 2.803

140 Partition-- 42g RL15, OAL 2.803
120 BT- 45g Varget, OAL 2.803

You're in quite the enviable position! I'm a 7mm junkie. When heading out to hunt mule deer, I never leave the house without my Nosler Patriot 7mm08/140 AB combo, or one of my 7RemMag's and 160 AB's. Good luck!
