My wife has used a Remington 700 Mountain Rifle in 7mm-08 for years on mule deer, elk and pronghorns. It shoots accurately, doesn't kick much and works very well on game with 140 grain bullets (mostly Accubonds in recent years). I think it has a slight advantage over the .308 for open country hunting in that it shoots a little flatter with bullets of comparable SD. On the other hand, I think the .308 has a slight advantage on larger game. The differences are pretty small though. Either one works very well for most North American hunting. It mostly gets down to personal preference.
