I like a 3 X 10 scope and 90% of the time I will have it on 10 power.Has nothing to do with what I need to kill the animal,but often there are small differences in antlers that effect my decision to shoot or not that I simply cannot see at low magnification.I also think that if you are having problems finding your target in the scope at any magnification you need to practice more with that rifle.If you can shoot a bird out of the air with a shotgun,surely you can put a rifle on target.Also,any equipment inaccuracy is added to your own shooting flaws,so the less the better.But,the difference between 1/2 inch and 1 1/2 inch is usually irrelevant.Now,I'll probably miss an artery by 1/2 an inch on the biggest buck in North America.
