I will admit up front that I've never actually used a 7mm-08 at all......but I have shot the 7x57mm (same catrdge with a different shape) a lot.
To me, the "secret" to any smaller, light caliber round is penetratin and heavy-for-caliber bullets. I really like the 175 grain bullets, but velosity is cut enough to really limit range. A good compromise is the 154 grain bullets wich allows an easy 300+ yard range with great penetration and hitting power.
The 139-145 a bullets also work great on deer size game, but I shy away from lightweght 120 grain slugs.
Couldn't agree more. My old 7x57's also worked best with 139 and 154gr bullet's. I wouldn't bet the farm on lighter bullet's.
