I recommend you buy the best scope that you can afford
saying that for what you have described I would recommend the 4-12x50 vx2 leupold
leupold because it has a full lifetime warranty
and 4-12x50 because its all you will ever need for the type of hunting and longrange shooting you are talking about
I have used one at little river (back when I thought the ssaa were for the shooter) at 500 regularly on my 300wm shooting 3 inches and under on paper
not shooting that ridiculous big round steel lid they have there that people think is a considerable effort to hit
anyway the 4-12x50 leupold scope is plenty but as I said get the best you can
