RE: SCOPE MAGNIFICATION
You could try looking into the new side focus Nikon 5-20x44. I have one and I personally think it is a great scope. But as stated above, I do not believe 14 or 16 is quite enough for the distances you are taking about. I also have the 4-16x42 New Nikon, and I love it also but I don't believe it would give you the site picture you are wanting. But that I just my opinion..... just as there are deer hunters who don't see the necessity of anything over a 7 or 9 power scope. But I don't use anything less than a 9x for deer hunting and most of my scopes for deer are 12 , 14, 16 or 20 x.
Good luck
