If it were me I'd step down to 2 1/2 or 2 3/4 with a 32 MM obj lens . They are more than enough power to shoot 300 yards, and much quicker on target. The exit pupil on these is 12.8 and 11.6 MM, The human eye can only use 5-6 MM so any extra size to the obj. lens is wasted. I use a 2-7X33MM on my .375 and have never turned it above 2X while hunting. A low powered, low mounted, scope can be faster than open sights with a little practice. Given that you live in Alaska you could be in a position to need the speed much more than the extra power.
