I’d limit my shots to under 300 yards, although a 7mm/08 will certainly kill deer at much longer ranges. As for bigger game, I’d cheerfully take it after anything except big bears. With bullets such as the Winchester Fail Safe, it will do the job.

I own a 7mm/08. I'd like to know its maximum range for deer, and if it can handle bigger game.
