Your scope question involves field of view, paralax, weight and a few other factors. A hunting scope choice is give and take considering several key factors. You got to pick one that best suits your individual hunting style. Most of my hunting is in grizzly country where I may need to get on a close moving bear quick, or a moving elk in timber. Therefore I use a lightweight 2.5-10 mil dot with 42 feet field of veiw. It takes quite a bit of practice to be able to use a scope like this long range because there are no paralax adjustments on it. I can easily take big game at a half mile with it plus have the best opportunity to save my life with a grizzly encounter.
If you are shooting small targets at long range then a high power scope with a paralax adjustment is neccesary. With the high power scope you are limiting yourself to long range shooting at fixed (stationary) targets. I have seen many trophy animals walk away because the shooter couldn't get the high power, small field of veiw scope on it and adjust the clicks. Animals I would have taken with my 2-10 mil dot. So some people go with the in between powers like the 3-12, 4-14, 4-16. The Nikon Monarch has very good field of veiw for a 4-16 scope. About the same as a 3-10 Leupold. The Monarch is in a good price range with excellent glass also. Hunting brings many more factors into the equation to consider than just shooting tight groups at long range targets. Unfortunately it takes a lot of practice (money) to find out what is best for you or what you can shoot accurately. A book could be written here so I will stop.
