I will be moving to Alaska in March for possibly the next 2 years.While living there I would like to spend some time hunting.I will be taking A Winchester model 70 in 300wm with me.Before for I leave I would like to upgrade the present 3x9x40scope that came on this rifle.I do have a Leupold M8 4x ,and was wondering if this scope would be a good choice for hunting in central alaska or if purchasing another scope would be a better opption
