I too would suggest the Leupold 2-7x but I am willing to take it a step further. I think this rifle would take any of non-dangerous and "dangerous" game animals in NA with ease given good bullets. Would it be my first choice to grizz? No, but given quality bullets you would be fine. A .270 WCF is a howitzer compared to a .30-.30 and how many grizzly have been taken by those? Tons. Hell I read just the other day of one in B&C book.
