Lived and hunted on Adak for three years, also have made many hunting trips in the state. While living on Adak I had one rifle, a 30-06 with a Redfield 4 power and a duplex reticle, no problem with shots to 400, practiced alot learning hold over. Of course those were the days before hold over reticles and turrets became the norm. Illumination would not be necassary as a good glass goes along ways in low light.
A 6x Leupold of your choice would do a great job.
The scopes that make the trips to Alaska now days is the Swaro and Kahles 1.75-6x42 with duplex reticles.
