I am planning on headingto Africa in the spring of 2014 and am buying a Winchester Model 70 375 H&H Mag for the trip. I was wondering what would be the best size scope to put on it? I am thinking of a Leupold 2-7 or 3-9 but I am not sure. As I live and hunt in Alberta I would like the rifle to be versatile enough for Elk and Moose as well. Any suggestions?
