It is a great round that has spawned the 7mm/08, 260and 243. Which are probably as good if not better for deer as well. IMO, I would use the 243 for deer and lopes, 7mm/08 for Mulies and Elk and 308 for anything larger.. But that is just because I have a rifle in each caliber and I really hate to leave one in the safe too long before I use them.. I wouldn't want them to feel neglected..
