If you only had the choice between those two calibers which would you choose. I have both right now and would like to pick one for a project to custom. I love both of them and they both shoot really nice. This rifle would be used on everything from deer to moose. It will mainly be used on Moose. My party trys to do a moose hunt every year, and if not then it will be a black bear hunt with the odd year being Caribou. So given the fact that it will be mainly used on moose from 0-600 yards which would you choose and why?
