It will work, but the scope he has is strictly for open country. I agree with those who recomended a 3X9 or 3.5X10. If nine power won't do the job, the animal is just too far. Deer and such don't always stand around waiting for the bullet to get there. Should they move, you are in for a bad hit. Wind becomes a major factor at extreme ranges. There is too much emphasis on long range shooting now, even though the average guy can't hit an elephant under field conditions. In most of the videos showing game taken at 600 yards, the shots were taken by experts who could have cut the distance in half, but that would not have been so dramatic. I got my first deer while Ike was in his first term and killed more than my share of deer, elk, and moose. Never have I needed to shoot much over 300 yards with most animals being under 150 yards. Shooting targets at extreme range is great fun, just not animals. Also it is very difficult in dark rainy woods to quickly pick out an animal at much over 3 power. Sorry, I got back on my soap box again.
