The purpose of the scope is to enable the shooter to see his target. But the magnification that might seem to be a gift from the gods at long range, can be a disaster at short. Large scopes, particularly those with 50mm+ objectives must be mounted high to allow the bell to clear the barrel, exposing the already delicate instrument to more potential damage. On some rifles this can place the comb low on your chin; so much for a repeatable cheek weld. The higher low end power can be an issue when attempting to find a close range animal in the narrow field of view, then there can be additional problems associated with an unexpected low point of impact when a round is fired at very close range. Of course none of us ever goes afield with a rifle they are unfamiliar with. IMHO, 3.5-10X40 with a 30 mm tube is as much as you want to put on a general purpose big game rifle.
