When I was young, I used to have trouble finding deer with my 32mm scope at the time. The problem was not with the scope but with my natural skills of putting my gun up and naturally being on the animal. After almost two decades of using that gun, I don't have that trouble any more. I have a few 50mm scopes, but decided I don't like them. It looks retarded on a gun. Has extra wieght, which recoil can can effect its zero. Cost a bunch more. I mean if I need to see animals, I will use my binocs. Not a rifle. Thats alot of movement for those who use thier guns as binocs. As far as 40mm scopes, thats about what I want. Its all tradeoffs. You can mount it pretty low. Have decent light gather. Decent FOV. So thats about right with me.
