First off, welcome to the forums....you should be able to get opinions on almost anything you wish to discuss here.
As far as your question about the accuracy potential of the 7-08, there are lots of people on here that will give you their experiences with it, I'm sure.
Personally, I found that mine (700 CDL) likes 140 gr. Accubonds best with a healthy charge of IMR 4350. The accuracy is quite acceptable for my needs. As with nearly any gun, you gotta find out what combination it likes best. After going thru many various bullet/powder combos, that's the one I finally settled on for that gun.
I really think you will enjoy the 7-08, and may have a hard time getting it away from your wife.
