A fixed 2X is arguably sufficient, but the option of cranking up to 6X helps with precision shots at longer ranges. Objective lenses on these dangerous-game scopes rarely flare wide because at these low magnifications, they don’t have to. At 4X, for instance, a small, 20mm objective produces a 5mm exit pupil (EP). At 2X, this becomes a 10mm EP. The human pupil only expands to about 7mm. In daylight, it shrinks to as small as 2.5mm. A 5mm scope EP combined with fully multi-coated lenses is more than bright enough, even for a charging black buffalo in the woods. An illuminated reticle is a smart option, the red instantly directing your eye to the sticking spot.
